Gwozdz is a Polish family name.  Other Slavic countries have family names similar to Gwozdz.  The word gwozdz means nail in Polish.  It seems there is an archaic Slavic word gvozd meaning forest, so that may be an original meaning for the name.  Accent marks are used for the Polish name Gwozdz.  It is pronounced Gvoozhj.  The oldest document I know of with the name Gwozdz is from 1386.  There are quite a few documents with Gwozdz from the 15th century.  I found microfilm records of Gwozdz vital records from the 17th century.  I trace my ancestors back to the end of the 18th century in Wadowice Gorne, a parish in the south.  I know of  14 parishes that have microfilm records of Gwozdz people before 1850.  No doubt my list is a small sample of the total parishes that could be found with old Gwozdz records.  I figure there are about 11 thousand people named Gwozdz in the world today.  The name probably originated independently many times.  Most of the 8,800 people in Poland named Gwozdz live near Katowice and Krakow, in southern Poland.  I conclude the name originated most often in the south.  Most of the originations were probably commoners picking the name Gwozdz around the year 1600.  I figure Polish microfilm records are good enough that  there is about 1 in 4 chance you can document your Gwozdz family tree back to the middle of the 18th century.  There were lots of Gwozdz families by the 17th century, so the chances are slim that two arbitrary Gwozdz genealogists will find a common ancestor from the 18th century.  There are many towns in Poland with a name similar to Gwozdz.  If you are male with the family name Gwozdz, please consider having a Y-DNA test done to see if we are descended from the same male line.

Gwozdz Accent Marks and Spelling

I avoid accent marks in most of this web page, in case your display has trouble with accent marks.  The name Gwozdz in Polish is traditionally spelled with three accent dashes:  over the o and over both z’s.  All three dashes are like the French acute mark.

Like this:  Gwóźdź

However, Polish people often write the name without accents, or they use one or two dashes, or they use one or two dot accent marks, with or without dashes.

For example:  Gwoźdź, Gwóżdż, Gwózdź, etc.

There are other spellings and name variations.  I’ll return to more details about Gwozdz Spelling below, after I mention the Rymut Name Dictionary.

Meaning of Gwozdz

Every Polish dictionary tells us that a gwóźdź is a nail.

My late cousin Eugene Iwanski had an eight volume unabridged Polish dictionary that was published about 1900.  Eugene looked up gwóźdź for me.  In addition to nail, it means a bung or spigot of a barrel or cask, the tang or tail of a knife that goes into the wooden handle, a metaphorical word for troubles or worries, and a card exchange between two card players.

There is also a little known archaic meaning of gwozdz:  forest.  I discuss “forest” below.

The name gwozdz might have yet other meanings.

Other Countries with Gwozdz Equivalent

The word for nail sounds like Gwozdz in many Slavic languages.  No doubt there are equivalent names that originated in other Slavic countries.

“V” is not used in Polish.  The Polish language uses “w” for the “v” sound.  Most Slavic languages use the “v”, or use “v” when translated from the Cyrillic alphabet.

I know there is a Russian family name equivalent to Gwozdz.  In Russian, the word for nail is pronounced Gvozdi, with a y sound at the end.  I have asked a number of Russians if they have heard of a Russian name like Gvozdi;  many of them answered yes; some of them said they personally met someone with that name.  During a business trip to Russia I called myself Gvozdi and everyone assumed the name was Russian.  A web search for “Gvozdi” provides many hits:  A Moscow night club named Gvozdi came up on web searches, but it seems to have closed around 2005.  A 2003 Russian horror movie named Gvozdi was released in the US as “Nails”.

Many Slavic “g” words are pronounced and spelled with a hard “h” sound in Ukrainian, Slovak, and other Slavic languages.  That hard “h” is difficult for most English speakers, except in Scotland, where they spell this as “ch”, for example in “Loch Ness”.  Spanish also has “g” and “j” words pronounced with a hard “h”, for example the name George is spelled Jorge and pronounced as “Horhe” with both “h”s hard.

My linguist cousin points out that the Ukrainian word for nail, possessive form, is written hvizd.  I found a Michael Hvizd on the web, and I once worked with a Mike Hvisdos.

Ed Gwozda contacted me by email in 2011.  Ed knew a Czech linguist who assured him that Hvozda is a Czech name meaning forest.  Ed speculates that his Polish family might be of Czech extraction, with the “Hv” changed to “Gw” in order to render the Czech sound into Polish spelling.  I asked my linguist cousin about this.  He found (Jan 2011) a Czech Wikipedia [] entry that he translated for me:

“Hvozd is a deep, extensive, often boundary forest. The word comes from Old Slavic gvozd, which is a variation of Indo-European chvorst (chrast). The term hvozd is close to the words "les" and "hora" in its original unitary? meaning. The term hvozd is not currently used in contemporary Czech, it has been preserved primarily in local names for forested growth and hills such as Branzosky hvozd or Kralovsky hvozd, both in the Sumava mountains. Hvozd or Hvozdec is also the name of several Czech villages.”

My impression is that most Gwozdz people worldwide are of Polish origin.  I have not researched name dictionaries in countries other than Poland and US, but in Poland and the US the name Gwozdz dominates the “Gv”, “Gw” and “Hv” type names.

The common German name Nagel also means nail.

The name Nail is more common in the US than Gwozdz.  I know of a few Gwozdz people who changed their name to Nail.  I wonder how many of the Nail people in the world are Gwozdz people who changed their name.


Y-DNA is the Y chromosome, carried by males and passed from father to son.  Just like a family name.  It will be neat to compare Y-DNA types for several Gwozdz men to place them into various different Gwozdz Y-DNA male lines.  It will also be neat to identify distant relatives in my Gwozdz male line (and yours).  I started a Gwozdz project where Gwozdz males can compare their Y-DNA test results:


As a first test, I recommend the 37 Marker STR test


If cost is an issue for you, let me know;  I can help;  [email me]:

If cost is no problem, I can recommend a better test.

I recommend because my project is there, but there are other DNA testing companies that can provide tests.  If you already have Y-DNA data from another company and you are a Gwozdz, please let me know and I’ll help you compare your data to the Gwozdz project members;  [email me].

There are quite a few web sites with a general introduction to the subject of genetic genealogy, for example [wiki], [Genographic],and [FTDNA].

My Y-DNA haplogroup is L540.  I have a separate web page about this:


DNA may not verify Genealogy records because of non paternal events [NPE], such as adoptions, illegitimacies, cuckoldry, etc.

My findings so far (2016):

A Gwozdz third cousin of mine is my closest Y-DNA match which at least verifies our immediate genealogy.

Kargul is a family that I have found to be my closest Y-DNA match, not counting my 3rd cousin.  I found 1820 records for this family living in a village in Poland only 20 miles away from the village of my Gwozdz ancestor.  Details:


Nowak is a family name for my next closest Y-DNA match found so far.  Our common male line ancestor may have lived 500 to 1,000 years ago.

Gwozdz:  I have Y-DNA results for only one other Gwozdz man, and he is not even close;  our common male line ancestor lived more than 20,000 years ago.

I allowed myself to get very speculative toward the end of this long web document.  I separated the speculation to the end, so that you do not doubt the quality of the research that went into the bulk of this document.  That means there is a lot of repetition, where I return to topics for more speculative discussions toward the end.

No Gwozdz Ancestors In This Document

This document is an overview about the name Gwozdz.  There are no family trees in this document.

I have done quite a bit of genealogy research about my Gwozdz ancestors.  I submit my data for my ancestors, and for other Gwozdz records that I collect, to the [LDS site].

If you are looking for your Gwozdz late 19th century ancestors, my data is unlikely to be of help to you.  I concentrate on the oldest records, mostly before 1820.  If you have traced your family back to 1820, then you know which microfilm has them and you do not need my help.  Tell me about your results, however, so I can add your parish to my list of Gwozdz parishes below. 

If your ancestors come from a parish within 50 km of Wadowice Gorne, then you should contact me.  I might have some information that helps.  Maybe we can work together in a search for a common ancestor.

Polish Names

There are a number of good [books] on Polish family names.  Most large libraries have at least one of these books.  [PGSA] sells these kinds of books over the web.  For an introductory book in English, I recommend the [book by Hoffman].  More advanced name books written in Polish are discussed below.  The [RootsWeb] site has more information and links concerning Polish names.

Books do not tell you when and where particular Polish names originated.  Some noble names are exceptions, with well documented history.  For most Polish names, there is no historical record of origin.  I am confident with this statement, because I have discussed this issue with  people who study Poland and Polish names.  Hoffman, in his book, also points out that most Polish names do not have a history record.  One purpose of this web page is to document what I have learned about the name Gwozdz, and to document my reasons for concluding that the name is mostly from the south of Poland.

Heraldry and Coats of Arms

“Heraldry” is the word used for the study of noble families, and for the study of coats of arms.  The Polish word is Herb, plural Herby, inflected form Herbarz.  There are a number of books and web sites on the subject.  Look for “Coat of Arms”, or “Herald”, or “Herb” in a book title or web site for information.

I am suspicious of these.  Most of the web sites are selling something.  My impression is that modern commercial products like these, even books, may be based on flimsy evidence, and they almost never provide references as evidence.

I suppose in the distant past those climbing the social ladder found ways to claim upper class origins, and they may have paid for a coat of arms even in years after coats of arms were no longer used as emblems in battles.  So I am skeptical even of references that are a few hundred years old.  That said, here is what I have found for Gwozdz:

Marek Skarbek Kozietulski has helped me by email on this subject.  He recommended a reference book by Zernicki, published in 1900, with names of Polish nobility, including lesser gentry (petty nobles).  I am writing a more detailed description in my on line book;  when it is updated search for “Zernicki” in:


Google scanned this Zernicki book.  I downloaded it in 2016 as a pdf file, 81 Megs:  []

If the download does not work, try a search for:  “Der polnische Adel und die demselben hinzugetretenen anderslaendischen Adelsfamilien” by Emilian von Zernicki-Szeliga, Hamburg, H. Grand, 1900”

Zernicki is credible because for each name in the list he gives references to older books with more information.  Zernicki lists:

            Gwoźdź. - Schlefien 1486 (Kpt. -  Mlch. - Weltzel) 

Kozietulski explains that the “fi” is a hard “s”, and “Schlefien” means Silesia.  Those 3 reference codes refer to:  Kutopatnicki 1789, Malachowski 1790, Weltzel 1881.  The titles are given by Zernicki for those 3 books;  they sound like older lists;  I suppose if we find these books they might refer to yet older documents with information about Gwozdz nobles in Silesia during the 15th century.

In other books, the oldest Gwozdz reference I have found is a 1386 legal summary that mentions a nobleman;  I discuss this in detail below.

My favorite is 1460 document that mentions a nobleman, Peter Gwozdz.

I found thousands of Gwozdz vital records on microfilm for the 17th through 19th century.  The ones I found so far are all clearly records for commoners, because personal status was usually written in records during those centuries.  Even the petty nobles (Szlachta) were recorded with a proper honorific.  I have no idea if any of these (or how many of these) Gwozdz commoners are actually descended from Gwozdz gentry.

I have seen purported Gwozdz coats of arms illustrations for sale on the web.  My aunt purchased one by mail order many years ago, and I have a color copy of that one.  I also saw a “Gwozdz Scroll” for sale on the web. 

I spotted one web reference to a Gwozdz landowning family “of Belgium between the 11th and 12th centuries”.  I doubt it, but I may research that one of these days.

Rymut Name Dictionary

Kazimierz Rymut put together an alphabetical listing of all the family names in Poland.  For each name he provides the number of how many people in Poland have that family name.  He used the census database from the 1900 census, so almost everyone in Poland is included.  The result was published in 1992, and is available on the web.  Rymut updated the listing in 2003, using the 2000 census, and published it as a CD.

I discuss Rymut in more detail, with web links, on page 154 of my on-line book:


When I update my book, the page may change;  do a search for “Rymut”.

The 1992 Rymut version, based on 1990 data, breaks down each name count by [province] (not the same as the most recent provinces in Poland).  The 2003 version, based on 2002 data, breaks down each name count by [county] and also male vs female.

I used the 2003 CD to compile tables from Rymut.  The results are presented below in this document.  Let me briefly summarize the results right here:  There are 8381 people in Poland who spell their name Gwóźdź.  All the other obvious spellings and accents of Gwozdz together add up to only a few hundred people.  There are several distinct names that are definitely variations of Gwozdz, such as Gwoździk and Gwoździewicz that have over a hundred people each, but none with a thousand.  Two names, Góźdź and Gwiźdź, with a couple thousand each, look like they might be considered Gwozdz variations.  Details and discussion below.

I used the 1992 Rymut version to compile a table of where in Poland Gwóźdź people lived.  Details below.  Summary:  most of them live in the south of Poland.  61% of the people named Gwozdz in Poland lived (in 1992) in a cluster of 7 provinces around Katowice.  I presume that means that the name originated there, perhaps more than once.

US Census Names Sample

The US Census Bureau has a [list of surnames] from the 1990 census.

Gwozdz ranks 25,550th in the US.

Previous versions of this document of mine had a link to be the 1990 US census - a web page engine that allowed us to type a name and determine how common that family name is in the US.  That page is gone.  I cannot find an engine or a list for the 2000 or 2010 censuses.  From my notes, it is clear that the 1990 list of surnames (link above) is the same database that was used previously by that engine.

When the web engine was available I studied the 1990 data base and determined that actually, the rankings from 24,960 through 25,873 are a reverse alphabetical listing of those names with exactly 22 people in the data base sample of 6,290,251 people.  In other words, Gwozdz is in a 914-way tie for a ranking around 25,000.

That means the percent Gwozdz in the US is 22 divided by 6,290,251 = 0.00035%.

That is 3.5 Gwozdz per million people.

22 people is not a very good statistical sample.  However, I can provide a sanity check on this percent.  In the 1970’s, while delayed at the Chicago airport, I found a room with a display of all the phone books of the large cities in the US.  I browsed for an hour or so and found at least one Gwozdz listing in many cities, and I found a few Gwozdz listings in most of the largest cities.  In the 1970’s, most families had a phone book listing, and only one listing, so a listing represented a family of a few people.  This informal study gave me about the same estimate for Gwozdz in the US, a few per million.

That web page data is from the 1990 census.  Assuming the same percent in 2016, with 325 million people in the US, I calculate that there are 1137 Gwozdz in the US.  In other words, roughly a thousand Gwozdz in the US.  I rounded this down to a thousand to make clear this is a very rough estimate;  it might be off by a few hundred;  it is more likely a little larger than a little smaller than a thousand.  I calculated this number another way below and also came up with roughly a thousand US Gwozdz for 2016.

I checked all the most common variations of Gwozdz using that web engine.  None of them are in that US Census data base.  They are too rare.  Less than one per 6 million.  Accent marks of course are not used in the data base.

Web Search for a Name

As a quick sanity check on a name spelling, I enter it into one of the web search engines.  Google, Yahoo, etc.  Most of the spelling variations of Gwozdz come up with plenty of living people.

Gwozdz Pronunciation

The name Gwóźdź is pronounced Gvoozhj.

The G is like the g in “game”.  Not like the G in “George”.

The w in Polish has a v sound, as in “violin”.

The Gv combination consonant is very difficult for English speakers.  Here is a way to sound it out:  Imagine a game of tag where everyone must play a violin while running.  I would call this game “tag violin”.  Say that over and over quickly:  “tag violin”.  Try not to add a vowel between the two words.  Do not say “tag-a-violin”.  When you can say it without a vowel, remove the “ta” and say “g violin”.  Then remove the “ionlin” for the “g v” sound.

OK, it is very difficult.  Most English speakers have to add a soft vowel between the g and v, making the sound gav or gev, with the vowel as brief as possible.  Polish speakers can combine the gv with no vowel sound at all.  We form the g but hold it back for a split second, then let it explode along with a v.

The oo is long, like in “tooth”.  In Polish, the ó and u are identical sounds.  The o without the accent, however is soft, as in “dog”.  Gwoźdź without the accented o is pronounced Gvozhj.

The ź is pronounced soft, like the z in azure, usually indicated as zh in pronunciation guides.  Without the accent, the Polish z is the same as the English z.  So Gwózdź = Gvoozj.  With a dot accent, ż is also pronounced like the z in azure.  Few English speakers can hear the difference between ź and ż.  Pronounce ż with the tongue a little more forward toward the teeth;  pronounce ź with the tongue a little more to the back.

The dź is equivalent to the English j as in judge.  Or G as in George.  Polish dz, cz, rz, and sz are treated as single consonants.  In other words, the z is sort of like an accent mark when added after those letters. That is why Polish has so many z’s.  (English does the same thing with h, using h to change a sound to another one, usually unrelated to h, like ph, which is pronounced f.)  In our name, that first z is a normal z;  the second z modifies the d.  That makes dź doubly accented.  Without the accent, dz is as in English.  With a dot, dż has the tongue a little forward compared to dź.

The źdź combination consonant is very difficult for English speakers.  To practice, try “azure judge” and remove the “ure” for “azh judge”.  For this one, even Polish speakers “voice” the zh with a very tiny soft neutral vowel between the consonants.


In Polish, it is very common to pronounce a final dź as a ć.  That ć is pronounced ch as in church.  The Polish cz is equivalent.  So the name Gwóźdź (or the word for nail, gwóźdź) is often said as Gvoozhch.  That is a correct pronunciation.  Some books call it a rule that a final dź is always a ch sound, but I hear Poles say my name both ways.  The j sound is more common, in my experience.  I suppose this is an example of a language in the process of changing.

In Polish, it is very common to pronounce a final ź as a ś.  That ś is pronounced like the sh in “shoe”, except juicier, with the tongue more toward the teeth.  The Polish sz is equivalent.  I have never seen a Polish pronunciation book mention that a second-to-last sound ź might also be pronounced ś.  However, I have heard my name pronounced that way by Polish speakers:  Gvooshch.

I have seen it spelled that way.  Gwóść.  Funny, but the equivalent spellings Gwószcz and Gwuszcz are very rare.  I’ll drop the accents now for this topic comparing Gwosc to Gwozdz, in case your display is having problems:

In the 19th century microfilm records, I find my ancestors recorded both as Gwozdz and as Gwosc.  When I first started studying the microfilms, I was concerned that Gwosc might have been considered an entirely different name than Gwozdz.  I spent a lot of time putting together a proof that these two spellings are the same name.  I understand that Polish spelling had not been standardized until the 20th century.  I have seen many cases of both Gwozdz and Gwosc used for individuals that are clearly in the same family, for example with the same parents and the same house number.  Sometimes that happens on the same page of a record book.  There is a tendency for some record book sections (with the same handwriting ) to use only Gwosc and some sections to use only Gwozdz.  On the other hand, many sections use both, with a tendency for some families to use mostly Gwosc vs others mostly Gwozdz, like maybe the priest wrote how he heard the family members say the name.  I wonder if the word for nail was pronounced both ways at that time.  I have convinced myself that Gwosc is the same name as Gwozdz in the 19th century for my ancestors’ parish of Wadowice Gorne.  I understand that my conclusion may not be valid in other Polish parishes, and may not be valid at other times in Poland.

For that parish of my grandfather, I have a data base of Gwozdz and Gwosc records.  My data base has 101 records with the name written as Gwosc.  My data starts at the year 1777, with plenty of Gwozdz records, but the spelling Gwosc does not appear until 1807.  I wonder if that means that I caught the Polish language at the beginning of a change in that parish, or if I caught a change in record keeping spelling, or if maybe I just caught a change of priest.

I did spot a 1730 instance of Gwosc in the parish of Luszowice, 20 km southwest.

I find it very interesting that the o of Gwozdz usually has the accent, but I rarely see the o accented on Gwosc.  Recall that the accent changes the o sound to a u sound.  I suppose that means the tendency to change the pronunciation usually comes as a package:  Gvoozhj becomes Gvoshch but not Gvooshch.  I notice the same tendency in modern Poland per Rymut;  there are 54 Gwość but only 6 Gwóść.  I notice that both forms of Gwosc are rarer today compared to the 19th century.

I’ll ask my Polish linguist cousin if he has ever heard of an observation that óźdź at the end of a word often is pronounced ość but rarely óść.

Actually, there are a lot more variations.  The accent marks vary a lot.  I have data on accent variations below:

Gwozdz Accent Marks and Inflection

My Polish grammar is not very good.  My linguist cousin Joseph Armata pointed out to me that gwóźdź is the nominative case for the word “nail”.  The genitive (possessive) form “of the nail” in Polish is gwoździa.  “To / for the nails” is gwoźdiom.  The accent marks and the pronunciation change along with the inflection.  Polish family names are often considered genitive forms.  This is also true of place names.  In other words, accent variations are more than just spelling variations.  Inflections are part of the Polish language style.

Gwozdz Anglicized Pronunciation

I have to admit that my name is very difficult for English speakers.  I like to pronounce my name in the Polish manner, but when an English speaker tries to pronounce it, I have pity and drop that final j sound, and add a vowel after the G, for Gavoozh.

Most of my relatives use Gavoosh as the pronunciation.

Actually, people do not have that much trouble saying the name if they do not see it spelled.  Funny - seeing the name spelled out makes it more difficult to pronounce.

As you can imagine, I have heard many Anglicized pronunciations.  None of them is dominant.  The Gwozdz people that I have known do not seem to have a favorite as a whole.  I do not recommend any Anglicized pronunciation as particularly easy.

I suppose the most common anglicized pronunciation, in my experience, is Gwahtz.  That’s what my family was called in high school.  I never understood how that one came to be.  I don’t particularly like it.  Something about it, however, seems to appeal to English speakers, as the easiest way to pronounce Gwozdz.

Gwozdz Anglicized Spelling

I know of Gwozdz people who have changed the spelling of their family name to Gush and to Gust.  I doubt however that many of the people in the world named Gush or Gust are descended from Gwozdz ancestors.

Vital Records

The [Polish records] of births, marriages, and deaths are not too bad.  Records for the 18th and 19th centuries are better in [the south], where Gwozdz families seem to have originated.  If you know the town of your Gwozdz ancestor, you should be able, with effort, to trace a Polish family tree.

Most if not all Gwozdz families seem to have been Catholics in the 19th century.  The Catholic Church took care of vital records in Poland during the 19th century.

[Parish].  It helps to figure out the parish to trace Polish ancestors before WW I, because that is where most Polish records were taken and kept.  I have visited or contacted about a dozen parishes in south Poland, and so far they all have at least some fragmentary vital records from the 19th century.  I found one that has original late 18th century records.  My experience is that there are more records in the south than in the north of Poland.

Microfilm Vital Records

[LDS Microfilms] are available with church records of births, marriages, and deaths in Poland. Not all records have been filmed, but microfilms make it much easier to trace a family tree.  Most of the microfilms of Polish vital records are from the 19th century.  My impression, from studying about 30 parishes in the south, is that more than half the parishes have 19th century microfilms available.  Type a parish name into the [LDS Place Search] to look for microfilm numbers.

In the south of Poland, many of the microfilm records start in the 1780’s.  It is my understanding that the Austrian government started to emphasize record keeping in Poland during the 1780’s.  My impression is that more than 1/4th of the parishes in the south have microfilm records available today that are more or less continuous from the 1780’s.

I have done a lot of research looking for Gwozdz people in these microfilms.  My vital records data for my ancestors are available elsewhere.

This document has detailed discussion of some general observations about the name Gwozdz. 

Two Name Books Written in Polish

I’ll next discuss Gwozdz data from two [books] written in the Polish language.  My cousin Joseph Armata found them in the Pittsburgh library.  Joe, a Slavic linguist, copied the Gwozdz pages back in the 1990’s and helped me to understand the Polish abbreviations.  I later located these books at UC Berkeley.  I suppose other large libraries have these.  They are not on microfilm, because the copyrights are current.

Nazwiska Polakow.  By Kazimierz Rymut.  1991, Wrocław.  On page 129, the end of the G section, the last entry is Gwozd.

Słownik Staropolskich Nazwisk Osobowych.  By Witold Taszycki.  1965-67, seven volumes.  PAN, Wrocław.  On page 188 of the volume with G, the last Goź entry is Goźdź. 

Both works are alphabetical listings of family names.  The 1965 series of volumes is encyclopedic.  It seems to be a classic reference.  The 1991 book is dictionary sized, with much of the data obviously abbreviated from the 1965 series.  Both lump similar names together into one entry.  They cover family names and first names.

Both give the dates of old documents in which that particular name has been found.  Only the 1965 series also gives a code and page number for each quoted date, so that the document name can be located in the references.  Most of the references seem to be law records and ecclesiastical records.  The 1965 series provides a brief quote with the actual spelling of a few words surrounding the name.

The 1991 book gives the meaning of the root words while the 1965 series does not.

Both these references lump the Gozdz and Gwozdz type names together.  This surprised both Joe and me back in the 1990’s when we first saw this.  We never realized that the w was optional in some old Polish words.  More about Gozdz below.

The 1991 book gives the primary meaning of gozdz / gwozdz as forest or woods, with the polish abbreviation that indicates this is an archaic meaning, no longer used.  The secondary meaning is nail.  This also surprised us.  We were not aware of that old meaning.

The 1965 entry for Gozdz / Gwozdz starts with a brief summary, then subdivides the entry into two sections, the Gozdz type references and the Gwozdz type references.  Unfortunately, the 1991 book seems to copy most of its information from the brief summary of the 1965 series.  That summary is very misleading, because it lumps names of various spellings together.

The oldest reference is to a Gozdek, year 1222.

The oldest “zdz” type Gwozdz reference is 1386.  The person’s first name is Andree, an inflected Latin form for Andrew.  The reference abbreviation is Łęcz, which refers to law books from Łęczyce.  Someday I’ll try to figure out if these documents are actually available in a library in Poland.  There are quite a few Polish towns in my atlas with names like Łęczyce, Łęczyca, and Łężyce.  My cousin says this is the Łęczyce in central Poland.

Actually, our friend Andrew’s 1386 quote appears at the end of the Gozdz section, with the highly inflected quote “Contra Gozdzonem Andree”.  I am comfortable enough with Latin to recognize the “onem” as a grammatical inflection of Gozdz, not a name variation.  There are 1390 and 1392 quotes, also from Łęcz, catalogued in the Gwozdz section.  The 1390 quote is “Pro Andrea dicto Gwoscz”.  At first, I hesitated to conclude that this is the same person.  But I found excellent evidence in a 1451 quote that is listed in both sections:  “Iohanne Gwoszdz de Lappczicza … Johannes Goszdz”.  This hints to me that a person John Gwozdz has his name spelled two different ways in this document.  Another piece of evidence:  A Stanislaus appears in both sections:  one is Stanislaus Goszdz, year 1440, page 379 of source code AC, the other is Stanislaum Gvoszcz, year 1437, page 319 of source code AC.  There are only 5 total first names in the Gwozdz section, with 7 dates;  the fact that 3 of the 5 names match a name in the Gozdz section, with the same source code and with a close year really indicates to me that the two batches of names are mostly the same  people.  I don’t know if Taszycki missed this, or if his research group chose not to look for such matches.  Whatever, this is good evidence that at least during the 14th and 15th century the w in my last name was optional.  Please recall that Taszycki did combine these into one entry, but then divided it into 2 sections - Gozdz and Gwozdz.  I am objecting because it seems to me that the same people have been listed in both sections.

If my analysis is correct, then the brief summary in the 1965 series is very misleading, because it lists both an Andrew Gozdz and an Andrew Gwozdz.  The 1991 book copies this misinformation.

There are a total of 9 first names in the Gozdz section.  Fellows named Nicholas appear in both sections, but these seem to be 3 different people, not all similar years, with 3 different source codes, and two of them have a different town after the name.

My favorite is the 1460 quote: “Nobilis Petrus alias Gwoszdz de Lapczicza”.  First of all, this guy has my first and last name.  Secondly, that honorific “Nobilis” indicates nobility.  Actually, I would assume all these references are to people who are at least petty nobles, since I doubt peasants would be named in documents back then.  But I’m not sure of that assumption.  I have often found the Latin word “alias” in old Polish records from back when people were originating / changing their family name.

That Andrew must have been pretty important, because it looks like a total of 5 references, 1386 to 1400, refer to him:  2 at the beginning of the Gozdz section, 1 at the end of the Gozdz section, and 2 at the beginning of the Gwozdz section, all with the Łęcz source code.

The 1393 quote seems to name his town, with “Andreas dictus Gosdz de Odolino”.  My atlas does not have an Odolino type town next to a Łęcz type town, but I have not yet searched the gazetteer.  I often notice the Latin “dictus” in old records, probably meaning “called” for a name that was then recent - I’m not sure of this.

The 1400 quote also seems to name his town, with “Andreas Goszdz de Oczicze”.  Both the 1393 and the 1400 quote have the Łęcz source code.  I need to find out if there was an Oczicze town close enough to an Odolino, to verify this is the same person.

More confusion:  Taszycki actually provides two entries at Goźdź.  I have been discussing only the first entry, titled “Goźdź, Gwoźdź”, which has a brief summary and two sections.  The second entry is only one line, with “Goźdź c.f. Goszcz”.  In other words, Taszycki considers Goszcz a different name.  That seems confusing, since Goszdz names are included in the first entry, and a final dz could easily be pronounced cz.  I speculate that the reason for the second entry might be the Polish word gość, which is the word for guest, and sounds exactly like goszcz.  Perhaps the linguists feel it is imperative to have an entry for a common word.  This is in my notes from when I studied Taszycki’s books, but I do not see in my notes any details from the Goszcz section.

Regardless of how Taszycki categorizes all these names, this discussion puts me in a position to point out another possible confusion.  Let me present this point as a speculative example:  Suppose a person long before 1400 adapted a new name, Gość, intending to name himself as a guest.  However, the word gwoźdź, also pronounced goźdź, can mean either forest or nail.  Suppose back then there was, as now, a tendency to pronounce źdź at the end of word as ść or szcz.  After several generations the family might forget the original meaning, assume the name means nail, and permanently use the w.  (If you are clicking around, you might need to go back and read the topic above on Gwosc to fully appreciate this point.)

This is all a bit confusing.  I have a summary topic about the meaning of Gwozdz, coming up below.


I found this word in a Polish encyclopedia.  It is a flower.  There is a picture, with a half column description, in Polish of course.

I do not claim this has anything directly to do with the name Gwozdz, but we cannot rule it out.

I point out this tidbit mainly to show a gwozdz type word being used in another context.  The more often a root word is used in different contexts, the more often I would expect it to arise independently as a family name.

The plant does not have thorns, so I do not see any relation to the idea of a nail.  I wonder if it was common in the primeval Polish forest.

This is an 1890’s encyclopedia, available on microfilm number 997506, volume VI, page 447.

I wrote this up some years ago.  My late aunt, Cecelia Olsztyn, sent me a note when she read my report.  She told me that my grandmother used to grow this flower, and that the family called it gwozdzek, plural gwozdziki.  I suppose this word could be the source of the name Gwozdzek.  My aunt told me the English name for this flower is [Sweet William].


More discussion about Gozdz, mentioned above as an archaic spelling of Gwozdz:  I found one set of examples of the mixing of the two spellings Gozdz & Gwozdz, in records from the 1790’s.  This one example does not prove that in the 1790’s Polish people still considered Gozdz a correct pronunciation for the word for nail (or forest), because I have not seen any other instances.  This one example might have been a quirk associated with one priest writing records.

Here are the details for the example that I found:  Film 1978299, Parish of Laczki Brzeskie.  Records from 1786.  (Parish founded 1957;  the records were actually recorded into a separate book in the Przeclaw parish from which Laczki Brzeskie split off;  records before 1786 for Laczki Brzeskie are in the Przeclaw microfilms.)

Josephus Gwozdz married Catharina Siwionka on 9 Nov 1788.  A child was born was born on 9 Aug 1795 to Josephus Gozdz and Catharina Siwionka.

Simon Gozdz, wife Lucja, has 2 children born in house 37:  21 Mar 1786 and 13 May 1788.  Then, another child is born to Simon Gwozdz and his wife Lucja, again house 37, 5 Oct 1790.  Those are the only 3 Gozdz or Gwozdz children born in town 1786 - 1791.  The maiden name of Lucja is scribbled in all 3 records, and even looks like a different name each time, but that is a common problem.  Simon Gozdz is a witness at the 22 Oct 1786 marriage of Thomas Gozdz.  Simon Gwozdz is a witness at the 27 Jun 1791 marriage of Franciscus Gwozdz.

By the way, this priest usually uses an accent only over the last z for both spellings, sometimes the first z, never the o, sometimes no accent.  Once, he used a double accent over the last z of Gozdz.

1880’s Gazetteer

This 12 volume set is a classic work, still used in Polish libraries.  It gives a description and brief history of every city, town, and little village in Poland.  Actually, the area of the former greater Polish Commonwealth.  It has a long name.  Many people just use the first 2 words of the title:  Slownik Geograficzny.

The end of the G section is the end of Volume 2, microfilm number 920958.

PolishRoots has a [guide] to using it.  The entire work is available [as a CD] that can be purchased from [PGSA].

I got blown away the first time I looked up Gwozdz back in the 1990’s.  This Gazetteer has  35 Gwozdz type names of places!  They take up 6.5 columns on 4 pages.  It goes from Gosc to Gwoznica.  Places like Gwozdawka and Gwozdziarinia are there, in addition to Gwozdz, Gwozdy and Gwozdowice, and many more.  My linguist cousin helped me figure it all out.

I am not a linguist, but it seems to me that if 35 places have Gwozdz type names, there was something about the word that appealed to people at the time.  That makes it reasonable, in my mind, that perhaps a number of different people independently took a name like Gwozdz back in the times when people were choosing names.  I have never seen this line of reasoning published in a name book, but then again, I have not looked very hard.

It also seems strange to me that words with a root meaning “nail” would be used for 35 place names.  Recall, however, that an archaic meaning of gwozdz is forest.  This is speculation on my part, but it seems more likely towns would be named something like “Forestville” rather than “Nailville”.  More discussion about this below.

Perhaps at least one person named Gwozdz set up a village long ago and it was named after him.  Or conversely, perhaps at least one person moved away from of one of these villages long ago, so the people in his new village called him Gwozdz.  It is logically possible that I am named after a town, with nothing to do with sharp spikes of metal.

My 1990’s Poland road atlas has 2 of the Gwo… towns.  Gwoździany and Gwoździec.  Both are in the far south, but not as far south as the mountains.   Gwozdziec is on the Dunajec river, SE of Krakow.  Gwozdziany is SW of Czestochowa on highway 46.  That atlas also has several towns without the w, like Goszcz, Gozd, etc.

My 2006 Poland road atlas has 3 of the Gwo… towns.  Two different Gwoździec and Gwoźnica Gorna.  Also several without the w.

The Poland map site [] has 5 different Gwoździec, all in the south, all less than 40 km from Krakow, Tarnow, or Rzeszow.  I also checked this site for the one Gwozdiany and Gwoznica Gorna.  Typing just Gwo provides 14 place names to select from, some with multiple locations.  I checked most of them (in 2016);  they are all in the south.

The [LDS Place Search] yields 10 microfilm links for places that start with Gwo.  These are duplicate index entries for 5 towns.  One of them is in Germany, one is in the Ukraine and one is in Belarus.  The two from Poland are in southern Poland:  Gwozdziec and Gwoznica Gorna, near Strzyzow.

I checked out the records of Gwoznica Gorna.  Film 0766012.  I found no names starting with Gwo.  I found several Gwazdach birth records, 1800’s, children born to Bartholomew and Valentine.


This topic is a summary of evidence for my opinion that the name Gwozdz may have been originally intended to mean forest.  I mentioned this in topics above.  Here is my summary:

The best evidence is the 1991 book by Rymut, with forest as the primary meaning of gozdz / gwozdz, with nail a secondary meaning.  Here is the full entry:  “Od stp. gwozd, gozd ‘las’, także od gwoźdź, stp. też goźdź ‘gwoźdź, kołek’”;  stp. means old Polish, or an archaic meaning, not used any more;  las is the modern Polish word for forest or woods;  kołek is another word for nail.

I also mentioned the Czech wiki etymology entry above, where gvozd is described as an old Slavic word for forest, used today in Czech only for names of forests and for names of places intended to mean “forest”.

My linguist cousin found “Bruckner's etymological dictionary of Polish cites ‘forest’ as an archaic meaning for gozd/gwozd.”  It is possible Rymut copied this from the older Bruckner reference, so this may not be independent evidence.

I have not found any reference to a Polish or Slavic document from centuries ago.  Over the years I have asked a number of Polish professors to point me to a comprehensive Slavic etymology reference that would give specific references to old documents using gozd or gwozdz or gvozd as a word for forest.  No one could help me yet.  I’ll keep asking.  If you the reader know of such a work, I’d appreciate an email.

The Taszycki series of 7 volumes on Polish names does not give meanings, but lists many men named Gozdz / Gwozdz, starting in 1386, with references, a couple of which I checked.  Taszycki nicely demonstrates how variable Polish spelling was back then, with multiple examples of what seems to be multiple spellings for the same man.  Since Gozdz / Gwozdz goes back that far, it is reasonable to consider archaic meanings for the root word as the original intention.

Slownic Geograficzny provides 35 places in Greater Poland with names similar to Gwozdz.

A 2016 search of wikipedia for “Gvozd” turned up several entries, including Gvozd Mountain and Gvozdansko Castle, both in Croatia, although I did not notice any comment about the meaning of “Gvozd” in archaic Croatian.

It seems unlikely to me that so many places would be named after nails, but likely that many places would be named after forests.  Similarly, it is more reasonable to speculate that a Polish nobleman back around 1400, when noblemen were starting to use inherited family names, might consider Forest more likely than Nail as his name.

“Forest” is my favorite speculation on the origin of my name, but I cannot be sure.

Nailing a Cannon

Marek Skarbek-Kozietulski sent me a Polish web reference that describes a “gwozdz”, used by the medieval Polish military for disabling captured enemy cannons.  I am not very fluent reading such formal Polish;  my cousin Joe Armata read it and assured me that this web reference describes a large 4-sided nail that is driven into the firing hole of a cannon.  Joe points out that this reference is citing regulations and handbooks, so it is a credible report concerning this medieval instrument.

Here is the web link:  []

Iron;  Trap

Nedim Celik sent me emails in 2017 in response to my web postings.  Nedim pointed out that in south Slavic languages (such as Serbian), “gvoozhje” means “iron” although it is usually used to mean an iron trap or chains.  Sort of equivalent to the English “putting someone in irons”.  “Celik” means “steel”.  Celik also provided web links discussing the various etymologies of “gvozd”;  I hope these links work for you:žđe

Review Discussion;  Meaning of the Name Gwozdz

This is a review of the various meanings of the Polish word “gwozdz”.  The motivation:  What word did our male line ancestor take as his name?  Since there are roughly 11 thousand people with the name Gwozdz, it is likely this name originated multiple times.  So I am really speculating here about the various meanings that were intended by various men who took the name Gwozdz.

Most Polish speaking people say the name Gwozdz means Nail, period.  Back in 1993, I started my study with the simple assumption that Gwozdz means nail.  In my first documents, I speculated that my male line ancestor might have been a nail maker, although the word for that is gwozdiarz.  I now doubt that my male line ancestor who took this name intended “nail” to be the meaning because there are too many other possible meanings.  This topic is based on a lot of study over the years, but I don’t really know;  this is speculation:

Review of other dictionary meanings of gwozdz, mentioned at the top of this web page:  a bung or spigot of a barrel or cask, the tang or tail of a knife that goes into the wooden handle, a metaphorical word for troubles or worries, a card exchange between two card players.

Also the archaic meaning discussed above:  forest.

Also the medieval nail for disabling a cannon discussed above.  And the previous topic, iron trap.

My wife watches the TV show "The Voice", and I have overheard phrases like "you really nailed it" by the judges, as a compliment to contestants, meaning they sang the song just right.  So if "nail" in English today can be a verb meaning singing a song just right, then "gwozdz" in Poland during past centuries might have had any number of metaphorical meanings.


Another possibility:  change of spelling from another name.  Since the name Gwozdz has not been uncommon in southern Poland, maybe some people changed to Gwozdz from similar sounding names.  Gwość can be considered the same word as Gwóźdź.  Gozdz is discussed above.  Goszcz is pronounced the same as Gość, which is the Polish word for guest.  More common Polish words:  star is gwiazda;  whistle is gwizd;  both words are on lists of Polish family names along with various spelling variations;  I have been contacted by email by people with these two names.  Finally, an immigrant to Poland from another Slavic country with a Gv… type of name might decide to use the Polish spelling Gwozdz.

I suppose during the 18th century, when the last of the Slavic commoners without family names were selecting names for themselves, some may have been aware that Gwozdz was already being used as a name, particularly in the south of Poland.  Perhaps some families chose “Gwozdz” as a name thinking that “gwozdz” meant “nail”, perhaps unaware of the archaic “forest” meaning.  This is speculation;  I’m not sure.

Speculation Summary:  Maybe Gwozdz meaning nail was a common nickname in medieval times, like Spike is today in the US;  some families might have adopted the ancestor’s nickname.  Maybe a military man “nailed” several cannons during a battle so was thereafter called Gwozdz.  Maybe a man who moved away from one of those 35 Gwozdz places was therefore called Gwozdz in his new home town.  I suppose some local landlords took the name of their local village;  and I suppose some villages took the name of their local landlord.  Perhaps some men were taking the name “Gwozdz” to mean “Forest”.  Over the centuries, some families with other Gw… names might have changed the spelling to Gwozdz.

Years of Gwozdz Origination

This discussion should apply to most family names in south Poland, not just Gwozdz:

Since there are roughly 11 thousand people with the name Gwozdz, it seems likely the name Gwozdz originated more than once.

I found a references to noblemen named Gwozdz.  However, there are a lot more commoners (peasants) than noblemen (gentry), so it seems to me many if not most of the Gwozdz originations were by commoners.

There is no definite exact date when Polish people took up the custom of inherited surnames.  [Hoffman], in the 2nd edition of his book, discusses the topic.  Hoffman on page 4 refers to Chapter 3 of a book written in Polish in 1959, by Prof. Dworzaczek.  Hoffman translated that chapter as an article for the [PGSA] newsletter, Fall 1985, Volume VII, number 2.  (Back issues only cost $5.)

Noble families took up the custom of inherited surnames before the commoners did.  The first nobles who took surnames did not consider the names inherited.  Their sons may or may not have used the same surname.  The custom of inherited names was practiced by some Poles as early as the 14th century, but the custom was not firmly established by nobles until the end of the 16th century.  (This paragraph comes distilled from Dworzaczek through Hoffman.)

In other words, Andrew Gwozdz of 1386 was probably aware that some contemporary noblemen used inherited family names.  He may or may not have considered his name Gwozdz to be inherited.

Hoffman on page 4 reports that “… peasant surnames did not become firmly fixed until about the 17th and sometimes even the 18th century”.

Dworzaczek says that peasants used family names only from the beginning of the 19th century.  That did not seem right to me, so I communicated with Dworzaczek’s translator, Hoffman.  Hoffman points out that Dworzaczek’s research was mostly on nobility, and he apparently did not trust peasant names from before the 19th century.  Hoffman assures me that subsequent scholarship has established earlier dates for peasant family names.  In the microfilms, I have seen name changes in the late 18th and early 19th century records, so I can understand Dworzaczek’s mistrust.

My understanding is that in the south, under Austrian influence, commoners picked surnames earlier than in the north.  I cannot find the references where I read that, so I need to go back to the library and find a source.  Meanwhile, I do have some personal experience from the microfilms.  I have seen late 17th century records without surnames only in the north of Poland.  No doubt the date of the surname custom varied between sections of Poland, and from village to village.

I have seen many 18th century and a few 17th century record book microfilms from the south of Poland.  I have seen no indication of any people without family names.  The oldest records I have studied, for only a few parishes, date from the 1660’s.  Although the records are too sketchy to figure out family trees, specific family names are used continuously in specific villages, so surnames sure look inherited to me, even in the late 17th century, in south Poland. 

Therefore I conclude that Gwozdz name originations, in the south, started earlier than Poland as a whole.  A good guess would be that most Gwozdz originations were within 50 years of the year 1600.  A safe bet would be that most were within 100 years of 1600, including most name changes.

I have not tried to find name originations, so I do not know how difficult they are to document.  So far, I traced all my dozens of family tree branches back to villages without records from the early 17th century.

Name changing is one form of origination that continues to the present day.  I found a name change in 1805, in the north of Poland, in one of my mother’s branches - Banasiak.  I found a Gwozdz family (not my ancestors obviously) with clear documentation of a name change to Knap.  That means I found a Banasiak origination and a Knap origination.  These are rare.  I studied more than a hundred family trees to find these 2 changes.

I suppose it is unlikely I’ll ever spot a Gwozdz origination, but with lots of researchers looking someone might spot one.  Let me know if you find one, so I can mention it here.

Summary:  Noblemen using the name Gwozdz in the 15th and 16th centuries may or may not have considered that name an inherited family name.  In south Poland, most new peasant Gwozdz family names were probably chosen during the early part of the 17th century.  A few individuals may have changed their family names to Gwozdz anytime since.

Gwozdz Spelling and Accent Mark Variation

Reminder:  the style of this document is quick introduction first, more and more details later.  This topic is getting into the nit-picking details.  If you are still reading in order, then I guess that means you would like to see more details.  Here we go:

The next few topics are the results of my research using the Rymut CD.

I remember the nuns in grammar school insisting that I must use all three dashes when I write my name, or else my name is wrong.  (My school was in MA, and the students were all born in the US, but the nuns were fluent in Polish at that local Catholic school.)  The good sisters meant well to be sure, but the modern view is that an alternate spelling of a name is valid if people use it.  There are such things, however, as common unintentional spelling errors.  Lists of names have data entry mistakes.

I have heard Polish natives arguing about proper spellings of names, and arguing if a variant spelling represents a distinct name.  I enjoy Polish arguments, but there really are no general rules to distinguish spelling errors vs spelling variations vs distinct names.  It is the same in English.  Smythe is a different name from Smith for a family that has consistently spelled their name Smythe for a few generations.  On the other hand, there surely are families that use both spellings Smith and Smythe.  Very likely when a new name spelling emerged years ago, the family spelled the name both ways.  The process surely continues today.  So lists of spellings can be misleading.

That said, I nevertheless split my data from Rymut into 4 tables.  I used my personal judgment.  It came out as a nice presentation that way.  Please remember that I really made a single table, then noticed it was easier to understand if I broke it into 4 as follows.  The split worked well here, but in fact there is a continuous graduation from accent variations, to spelling variations, to name form variations, to names that might be distinct, to names that are obviously distinct.

The following table, from Rymut 2003, has the various spellings of Gwóźdź, for names that have 20 or more people in Poland using that name.  The second column is the number of people.

Name Spelling

Total People in Poland

















There are at least 20 more spelling variations, and some hyphenated forms, each with fewer than 20 people.  That would be another 2 or 3 hundred people. 

Conclusion:  Gwóźdź is by far the most common spelling.  This is the dictionary spelling for the word that means nail.  For all Gwozdz spellings, there are about 8,800 people named Gwozdz in Poland (in the year 2000).

Rymut, in the introduction to his work, points out that there are many errors in the data.  I wonder how many of these spelling variation counts are due to data input errors. I know they are not all errors, because I see such Polish spelling variations all the time.

Rymut has only 6 Gwuźdź people, with only that one name starting with Gwu.  That surprises me.  The u in Polish sounds exactly like ó.  I often see u and ó mixed in 19th century Polish record microfilms.  No significant mix today for Gwozdz vs Gwuzdz, I see.

As a sanity check, I typed Gwozd, Gwosdz, and other variations from Rymut’s list with fewer than 20 people, such as Gwuzdz, and Gwodz, into Google.  Each variation came up with real people web references.  These are all valid names.

Rymut’s database from the 2000 Poland census is available on the web (in 2016):


Some of the numbers that you get at that site are slightly different than the numbers from the CD.  I suppose that’s because of editing;  Rymut mentioned that he edited some errors;  maybe the webmasters also did some editing.  Some numbers are very different, I think because a city may or may not be included with the county.

Rymut’s database from the 1990 Poland census is also available on the web (in 2016):

Gwozdz Variations

The following table, from Rymut 2003, has names that I judge to be distinct names that are variations of Gwóźdź, for names that have 50 or more people in Poland using that name.  The second column is the number of people.


Total People in Poland





Gwozdowski (+ska)




Gwoździński (+ska)




Gwoździowski (+ska)


Gwozdecki (+cka)




Gwoździkowski (+ska)




Gwoździewski (+ska)






Gwoździański (+ska)


There are many pages of more names like these with fewer than 50 people each. 

Rymut explains valid technical reasons for listing the masculine “ski” names separate from the feminine “ska” names, but for this table the ski totals were very close to the ska totals, so I added them and combined them into one line each.

No doubt Gwozdowski, Gwoździowski, and Gwoździewski are considered spelling variations of the same name by many of the 402 people that carry these names.  No doubt many of them consider their name to be distinct from Gwóźdź, although related.

Some of those 133 Gwozda may be errors, but not all.  Gwozda perhaps should be in the previous table;  this one is a close call.  I judge that most of them consider their name distinct from Gwozdz, though related.  Same with Gwozdziej.

Gwość has a separate discussion topic.  I show there that in my grandfather’s village long ago it was the same name as Gwóźdź.  I really don’t know for sure, but I expect that today it is considered distinct but related, so I put it in this table.

Names that are not Gwozdz

The following table, from Rymut 2003, has names that look similar to Gwozdz but are definitely distinct, for names that have 1000 or more people in Poland using that name.  The second column is the number of people.


Total People in Poland







Goszczyński (+ska)


Gwiazdowski (+ska)


There are many pages of names with fewer than 1000 each.

The word Gwiazda means star.  Even though it looks a lot like Gwozda, I suppose it is a distinct name, with no relation expected to Gwóźdź.  Gwiazdowski is clearly a variant.

I judge Gwizdała to also be independent of Gwóźdź, although I’m not positive.

Therefore, I did not include many names starting with Gwi in my previous table of Gwóźdź variations.

The problem is a lot of names like Gwiazdz, Gwiaździński and Gwizdalski, which are not on my lists, but could derive from either star or nail.

The name Gość, which has a separate discussion above, has only 112 in Rymut’s list, so it did not make this table.  Goszcz has only 854.  There are many variants with less than 1000.  As I point out in the earlier discussion of this word, it might have been confused with Gwozdz many years ago.  That is probably not the case today, so I did not include these names with Gwozdz variants in the earlier table.  There is the possibility, however, that some of these people carry names derived from common Gwozdz stock a long time ago.

Names that Might be Gwozdz Variations

The following table, from Rymut 2003, has names for which I cannot judge a Gwozdz derivation, for names that have 200 or more people in Poland using that name.  The second column is the number of people.


Total People in Poland





Goździewski (+ska)










There are many pages of names with fewer than 200 each.  These are names that might today be considered Gwozdz variants by the people who carry them, or they might not.  So they should be in either of the two earlier tables, but I am not qualified to place them into either.

As discussed earlier, Góźdź is an archaic form of Gwóźdź.  I doubt that many of those 2816 people even know that fact.  I suppose some of them have an ancient name that was split long ago into descendants with both names Gozdz and Gwozdz.  I suppose some of them have ancestors that took this name only a few centuries ago, with no intention of an association with the name Gwozdz.  I suppose some of them consider their name equivalent to Gość.  In other words, the count of people with this name perhaps needs to be split, with some going into the tables of Gwozdz names, and some going into the table of names that are not Gwozdz.  The same discussion probably applies to other names in this table.  I am now talking beyond my competence in the Polish language.  However, I doubt that an expert Polish linguist would argue with me.  More likely such an expert would take interest in the data that I present in this document, and provide tentative additional comments without any definitive conclusions.

I speculate that some of the Gwiźdź count may represent Gwóźdź names with data entry errors, where the keyboard typist read an ó on a scribbled form as an i.  This form may also be related to the Ukrainian use of an i for the genitive case.  The name Gwizdz comes up with real people on a web search.  Edward Gwizdz from Rzeszow contacted me by email awhile ago;  he pointed out in response to my questions that in Polish a gwizdz is a whistle.  I should have checked my dictionary before asking.  My dictionary spells it gwizd.

This is the end of my 4 topics with discussion of my study of Gwozdz name variations.  The next topic concerns the provinces where they live, still from Rymut.

Provinces Where Gwozdz People Lived in 1990

In this topic I show that most Gwozdz people live in the south, particularly near Katowice.  It makes sense to conclude that the name Gwozdz originated mostly there.

For simplicity, this topic is restricted to the people in Poland who spell their name Gwóźdź, with all 3 accent marks.  That represents almost all the people in Poland considered Gwozdz today, but not the people with name variations that should be considered separate names today but may have descended from a Gwozdz family.

This topic is based on the 1992 version of the Rymut data.  Click on Rymut for the explanation of the two versions.  I used the 1992 version, because the totals are broken out only by [province], so it is much easier to work with.  The 2003 version has a much more detailed county break out, but it is more difficult to summarize.

There are only 6543 Gwóźdź in the 1992 version vs 8381 in the 2003 version.  That might be mostly population increase.  Rymut explains that he spent a lot of effort fixing errors for the 2003 CD version, so maybe he “corrected” some (not all) of the spelling variations.  For my analysis on provinces, the count change should not matter, because we presume that statistically there should not be a significantly higher percentage of errors in one county vs another.  I return to the 2003 version in the next topic below, for county analysis.

Also, since I am trying to get a hint of where Gwozdz people originated, the older data is actually better, since people are moving around a lot more since the 1991 break up of the Soviet Union.

The following table arranges the numbers from Rymut.  The [provinces] are the pre-1999 provinces.

18 provinces




2 provinces




49 provinces


2,021 of the 6,543 Gwozdz people of Poland live in Katowice province.  Almost 1/3.  It looks like the Katowice area of southern Poland is a major Gwozdz homeland.

Katowice province was on the Polish southern border with Czechoslovakia.  There are 5 Polish provinces that surround Katowice province.  Kielce to the north east is 2nd with 532, Krakow to the east has 359, Opole to the west has 334, Bielsko Biala to the south has 181, and Czestochowa to the north only has 108.

Tarnow to the east of Krakow is third with 436.

Most of the Gwozdz people are in this cluster of 7 provinces in the south of Poland.  The total for this cluster of 7 provinces is 3971, which is 61% of the total.  These pre-1999 provinces correspond to the post-199 provinces of slaskie, opolskie, and the western parts of swietokrzyskie and malopolskie.

On my map, I drew 2 overlapping circles of radius 100 km, one around Katowice and one around Krakow.  This elliptical area catches almost all the area of these 7 provinces plus a little of Czechoslovakia.

“Silesia” is a historical name for a region that is mostly in southwest Poland today.  Katowice is within that region, Krakow is not.  Wroclaw is more or less in the center of the region considered to be Silesia, according to [Wikipedia].  It seems Gwozdz is a common Silesian name.

Silesia was split during the 19th century between Austria (east), Prussia (north), and Germany (west).  My research experience is mostly in the Austrian section, so my estimates of microfilm availability in south Poland may not be valid for the other 2 sections.

Summary:  More than half the people in Poland who carry the name Gwozdz live within 100 km of Katowice or Krakow.

Nine other provinces have 109 to 247 Gwozdz people;  these nine are all contiguous to this cluster of 7, to the east and west, not to the north.  All 14 provinces in southern Poland have at least 99 Gwozdz people except two on the east edge.  Poland has 49 provinces;  all the other provinces have less than 106 Gwozdz each.  Warsaw province with its millions of people only has 105 Gwozdz names.

The other spellings and versions of the Gwozdz name have similar distributions, with much smaller numbers.

This does not prove that all the Gwozdz people descend from one family of Katowice.  It is possible, in fact it seems to me very likely, that the style of naming near Katowice was such that many families independently took the name Gwozdz.

Counties Where Many Gwozdz People Lived in 2000

In the previous topic, I used Rymut’s Polish 1990 census data to show which section of Poland has the most Gwozdz.  The 1990 data is better for provinces, but Rymut’s 2002 data is better for counties.  A county is called a [Powiat] in Poland.

This table has all the counties with more than 92 Gwozdz per the Rymut CD based on his 2003 analysis of the Poland 2000 census data.

Most of these counties are near Katowice, as expected from the previous topic.  The top 4 are in the slaskie province, of which Katowice is the capital.  In fact, 9 of the 19 provinces in this table are in slaskie, 5 are in 3 adjacent provinces, and 5 are in provinces adjacent to those.

We expect that most if not all of these counties had Gwozdz people living there in previous centuries.  I figure most of if not all of these had originations of the Gwozdz name in the early 17th century.

I expect most of these counties have Gwozdz records in the microfilms, at multiple parishes.  When a county name is typed into the [LDS Place Search] microfilm index, all the towns (parishes) with microfilm records are listed.  I tested the first 3 from this table in 2007:  Bedzin has only 2 hits, Bedzin itself and Wojkowice Koscielne.  Bedzin has records from 1636;  Wojkowice has records from 1618, so I suppose I’ll look at those someday.  Tarnowskie Gory has 12 hits - microfilm records for 12 different parishes in the county.  Katowice has many hits, but most of them are other information, only 2 are for vital records;  one is for the town of Myslowice;  the one for Katowice provides Jewish records from 1825 and Lutheran records from 1914;  I see no microfilms of parish vital records for the city of Katowice.

My Ancestors

My Gwozdz grandfather came from [Wadowice Gorne].  This is not Pope John Paul’s home city of Wadowice SW of Krakow.  This is a small town 100 km NE of Krakow, between Tarnow and Mielec.  I traced my Gwozdz ancestors back to the late 18th century in Wadowice Gorne.  There are no specific genealogy results in this document.  I submitted most of my ancestral vital records results to the [LDS Data Base].  My results are available on-line at the [LDS Web Search Engine], which directs you to CD #35 for more detail.  Copies of my on-line submission, along with more detail, and more genealogy research results not related to my family, can be found elsewhere by clicking from my [home page] associated with this document.

Gwozdz Documents, 14th through 18th Centuries

As explained above, there are Polish Language reference books, with lists of Polish names, giving references to documents where that name has been found.  The oldest Gwozdz reference that I located is for the year 1386, in a reference encyclopedia for Polish names through the 15th century, published in 1965, by Taszycki.

            I attended a conference in Krakow in 2010.  I took the time to examine that Taszycki 7 volume set at the Jagiellonian University Library.  Professor Michal Kokowski kindly helped me to understand the introductory explanation at the front of volume 1:  Taszycki explains that he does not list all Polish surnames, because he compiled his index using only printed books.  Apparently, many if not most of his printed sources were legal opinions, which had been compiled over the centuries.  Kokowski and I found the books for a couple of these legal references (Gwozdz citations).  They look a lot like modern books that you see on shelves in the offices of lawyers - with brief summaries of legal rulings.  Each summary has a reference to more detailed legal records, but those more detailed records were not available at the Jagiellonian Library.  I suppose some of those detailed records might be available at archives, but I suppose many no longer exist.  Taszycki does not explain exactly how many libraries he searched for books with lists of names.  Those 7 volumes look like modern Google searches - with the name plus a few words before and after.  Apparently, Taszycki used index cards to put together an index of Polish names, very similar to what Google is making today (2016), using computers.  Google is doing all words from millions of books.  Taszycki's index is family names from a large number of printed books that he studied in unspecified Polish libraries.  I also found a wiki entry about Taszycki, who died in 1979.

Taszycki has another work, published in 1969, with references to documents from the 16th through the 18th centuries:  Wybor tekstow staropolskich XVI - XVIII wieku, 1969.  I have not checked it.  I know that one cannot be complete.  I personally studied books from the 1780’s at parish rectories.  Taszycki certainly did not catalogue those.  I personally found hundreds of microfilm records of Gwozdz people from the 17th and 18th centuries.  I correspond with a lady who found many instances of her name at the Polish National Archives, in obscure fragmentary 17th century census records.

I don’t know what to say about 16th century references to Gwozdz.  No doubt the reference works have a good sized list of name citations.  Maybe there are plenty additional 16th century dusty documents in archive libraries that have Gwozdz mentioned but have not been catalogued in the reference works.  I’m retired - you go look.

The 1965 Taszycki series of books covers the 10th through 15th centuries.  All the Gwozdz references are 1386 -1480.  I already discussed these above.  These Gozdz / Gwozdz documents have reference codes:  Łęcz, AC, Hel, KW, Krak, U Prak, AGZ, DłBen, and KTn.  My cousin Joe figured these out.  They are, respectively:  Łęczyce in central Poland, Płock central, Krakow southeast, western Poland, Krakow again, Krakow diocese, Sanok southeastern, Krakow again, and Tyniec south of Krakow.  Please recall my analysis that most Gwozdz people in Poland today live in the south.  Glancing at the reference list, it seems like most Gwozdz people in the 15th century also lived in the south.  It is a long stretch to conclude, however, that these ancient Gwozdz are actually the ancestors of all the modern Gwozdz people.  It is possible, but I doubt it can be documented.  It is more likely that something about the regional preference for choosing names made multiple Gwozdz name originations through the years more likely in the south.

Gwozdz Microfilm Records, 17th and 18th Centuries

I have not studied the 17th - 18th century reference works.  However, I found Gwozdz family vital records in microfilms as far back as 1664.

It is difficult to arrange 17th century vital records into family trees for 2 reasons.  First, these old records tend to be fragmentary, with entire generations missing.  Second, these old records do not name parents at marriage, or grandparents at birth.  In some cases, age at marriage is not recorded, so matching a groom to a birth record can be guesswork at best.  Even in a village with very few Gwozdz records, the tendency is to remain very few, because population grew slowly back then, so it is not reasonable to place the Gwozdz records from a single village into a single Gwozdz branch unless there is some direct evidence.  After all, if we find two Gwozdz families having children in the same village, the fathers could be very distant cousins.

The same is true for most of the 18th century.  I have not been able to link any Gwozdz records into trees before the mid 18th century.  (I have only tried in a few parishes, however.)  I only have 4 trees started from before 1780:  3 in villages corresponding to modern parishes that were then part of Lubzina, and 1 in Luszowice.   In these cases, the Gwozdz births around 1750 seem continuous, and can be reasonably linked to later marriages with the age of the groom recorded.  Parents are named at birth, of course, so the named patriarchs were no doubt born around 1725.  These 3 have enough sons born in the 1750’s, and enough grandsons later, to assume that the line can be traced to modern times, although I have not traced these records past 1800.

For these old records in the south of Poland, both birth and marriage records are needed to document family trees.  If all the birth records exist, only fragmentary marriage records might work for a tree (with many branches lost).  Similarly, if all the marriage records exist, fragmentary birth records might be enough.  Usually, with most if not all of both marriage and birth records, nice family trees can be constructed.  The missing records are not a big deal, because a high percent of male lines disappear even from complete records (wars, migration, etc) so even 30% missing records do not make matters much worse.

Death records rarely help with tree construction, because rarely are family members mentioned in these old death records.

Birth records in the 17th and 18th centuries always name parents, although usually not the maiden name of the mother.  Records that start at a particular year, therefore, name males who we can assume were born about 30 years (surely 17 to 70 years) before the birth record.

The records really improve in the late 1780’s.  I figure more than 1/4th of the parishes in southern Poland have continuous records back to the late 1780’s.  When I say “continuous records” I mean “most of the birth and marriage records”.  Once continuous records are available, most families can be traced through the records, so the net odds of tracing your late 19th century Gwozdz ancestor back to the 1780’s are about 1/4th.

1772 is the year [Austria conquered the south] of Poland.  I have seen nothing special in the records at 1772.  1777 is a special year.  A new [table format] appears in south Poland on that year, in the Austrian style.  Columns are there for the age of bride and groom, and for house number.  All marriage records have the 2 ages and most have the house.  The 1777 tables are made by hand & ruler.  In 1784, a printed tabular form was introduced.  Many parishes have oldest microfilmed records that start in 1784.  Many parishes have records that start around 1787, using the 1784 form.  Daniel Schlyter published a nice short pamphlet about Polish genealogy that mentions this 1784 standardization in south Poland.  A book by Gerald Ortell has a lot more detail.  Both can be obtained from [PGSA Books].  I wonder what happened in 1787.  I noticed a few “Militaris” notes in the 1790’s, but no obvious record keeping changes during the 2nd and 3rd partitions of Poland in the 1790’s in the south where my ancestors hail from.  I do not have much experience with the microfilms closer to the Gwozdz heartland of Katowice, which was taken by the Austrians in 1795.  As I read the partition maps, Katowice is just barely on the 1795 side of the 1772 border.  My experience may not apply exactly to all the Gwozdz microfilm records.

I have been able to put together family trees for quite a few Gwozdz families, starting at the end of the 18th century.  In my ancestral parish of Wadowice Gorne, marriage records start in 1777, with excellent handwriting, and with fathers named.  House number is recorded.  Naming parents was unusual in marriage records back then, and the practice ended for many years when a new pastor took over in 1784.  Nevertheless, I was able in that parish to link multiple marriage records into siblings in a few families, with a named father who in some cases has a death record.  Some of these families have enough males to start continuous Gwozdz trees from the middle of the 18th century.  Unfortunately, my Gwozdz ancestor, married about 1795, is missing from the marriage records, so my line does not hook up quite that far back.  Fortunately, that inspired me to search for (and fail to find) his marriage record in the neighboring parishes, so I have a rough feeling for the percent of parishes with Gwozdz people.

You can find my family tree results elsewhere.  The Gwozdz family trees not related to me are not ready for posting on the web;  when they are I’ll post them, and I’ll change this sentence.

Gwozdz Microfilm Records, 19th and 20th Centuries

There are plenty of microfilm records available for Poland for the 19th century.  In the region of my Gwozdz ancestors, almost every parish has microfilms available.  I know that is not true throughout the south, because my paternal grandmother comes from only 50 km south, and in that region most parishes do not have microfilms of their records.  My cousin contacted the parish to start the work on my grandmother’s family tree, and I visited the parish to continue the work.  I roughly estimate that more than half the parishes of south Poland have useful microfilms available.

My experience is that most southern (not northern) parishes have at least some fragmentary records that have not been filmed, and dating from the 19th century.

Few 20th century vital records are available on microfilm for public research, for reasons of privacy policy.

Parishes with Gwozdz Microfilm Records

Here is a list of Polish parishes where I know there are Gwozdz vital records available on microfilm.  The parish name is actually the name of the town that has the parish.  The microfilm numbers are available on line by typing the parish name into the [LDS Place Search].

My research is biased toward my ancestral region, so may not be representative of the rest of south Poland.  This list has 14 Gwozdz parishes.  I suppose there might be as many as 100 parishes with microfilm records of Gwozdz inhabitants;  I don’t know.  The next topic below has more towns that I figure probably have Gwozdz people.

I submit my actual findings of vital records data elsewhere.

I cannot help you find your immediate Gwozdz ancestors, because my Gwozdz name research is almost all before 1885, and most of it is before 1820.

The code “WG” below is Wadowice Gorne, my ancestral Gwozdz town, 100 km NE of Krakow, between Tarnow and Mielec.

Not all these towns are on English language map sites.  Here is a Polish map site:  Type the name into the second box on the upper right of that Szukacz web page.  Not the top box - that’s for searching the web.  The Szukacz maps use the mouse to display map distances in km;  I used that for most of the distances that I give in this web page.

In the following notes, I mention if I know that the parish has more records not microfilmed, or if they informed me they do not.  If I do not mention, I do not know, because I did not visit that parish to ask.

The following parish paragraphs are arranged in order of the oldest Gwozdz records, with oldest date in boldface:

Przeclaw.  15 km SE of WG.  Microfilm records from 1660.  Oldest Gwozdz record that I have found:  marriage in 1664 of Katarzyna (Catherine) Gwozdz.  Grzegorz (Gregory) Gwozdz must have been an important man.  Greg, from the village of Korzeniow, was a witness at 9 marriages from 1669 to 1678.  Although these 17th century people from Przeclaw Parish could have easily walked, in less than one day, to my ancestral parish, I have no documents connecting them to my Gwozdz ancestors.  We are lucky that Przeclaw marriage records survived for the years 1660 - 1679;  I studied them.  Baptismal records survive from 1667 - 1670 & 1749 - 1759;  I did not study the baptismal records.  We are unlucky that there are no other surviving records before 1786, so Gwozdz families cannot be traced back before 1786.  Starting in 1786, the records seem continuous for the parish, kept in several books, separate by village.  A few of the villages have modern parishes, so the corresponding books have microfilms indexed under those village names;  see for example Laczki Brzeskie, below.  It seems that there were already a few Gwozdz families before 1670, living in 3 villages just south of Przeclaw:  Laczki Brzeskie, Podole, and Korzeniow.  The records for Przeclaw 1786 - 1800 have a few Gwozdz.  There is a birth index 1863 - 1936 in the microfilms, with plenty Gwozdz listings, almost all from the village of Podole, which is still in the Przeclaw Parish.  I suppose it would be possible to make descendancies for a few Gwozdz families from before 1800 to modern times, but I did not attempt to do this.  I studied Przeclaw because I noticed 17th century microfilms in this parish close to where my ancestors lived.  I suppose there are more south Poland parishes with microfilms of 17th century Gwozdz records, but I have not done a systematic search.

Olesno.  Updated 16 Feb 2017.  40 km NE of Opole.  This Olesno is in SE Poland, 215 km SE of WG.  Olesno has microfilm records from 1660.  I did not check these microfilms.  I noticed the data by typing “Gwozdz” into the Genealogies tab at  There are several Gwozdz records.  The oldest record is a marriage in 1673.  The indexed data does not include source references, but the data is obviously from the microfilms.  Olesno data are also indexed under Rosenberg:  Germany, Prussia, Schlesien Province.  Olesno is a county seat (Gmina), so searching for “Olesno” microfilms shows 37 hits;  35 of those hits are from towns in Olesno Gmina, because the Gmina is given as (Olesno) in the on line catalogue.  It looks to me like this Gwozdz data is from the large town “Olesno (Olesno)”, but I am not sure of this.  Two of the Olesno hits are for another Olesno only 27 km SE of WG, but that other Olesno is a small town near Dabrowa Tarnowska, also with microfilm records, which I did not search.  The microfilms are not mentioned in the on-line results, although this data is from the IGI and PRF database, and the on line data includes the submission ID Number.  By checking the submission itself at an LDS library, perhaps we could determine which microfilms provided this Gwozdz data, although I am not planning to do this research.  Two of the 37 Olesno hits for my microfilm search are for another Olesno only 27 km SE of WG, but that other Olesno is a small town near Dabrowa Tarnowska, also with microfilm records, which I did not search.

Luszowice.  20 km SW of WG.  Records from 1686.  Marriages of Jacob Gwozdz in 1687 and Joseph Gwozdz in 1690, but those oldest marriage records are fragmentary.  Continuous Gwozdz records from 1750.  I noticed these Gwozdz records because my Kmiec ancestor moved from Luszowice to Wadowice Gorne, so I studied the microfilms with the oldest Luszowice records.

Lubzina.  22 km SE of WG.  Records from 1634.  Marriage of Agnes Gwozdz 1698 in a village that has no other Gwozdz records.  Gwozdz families in other villages that are now separate parishes.  See the modern parishes of Paszczyna, Kochanowka, Pustkow, below.  No Gwozdz in the town of Lubzina until 1779.  The records are continuous, so obviously, Gwozdz people moved into this parish from elsewhere, and continued to move from village to village.  Or maybe someone changed his name to Gwozdz?  I studied Lubzina parish because I was hoping to connect my ancestors to the Gwozdz ancestors of Jarvis Gust, in Paszczyna.  I found no connection.

Kochanowka.  21 km SE of WG.  Records from 1634 with Lubzina.  Continuous Gwozdz records from 1721.  I suppose there might also be Kochanowka records with the closer parish of Ocieka.  Independent Kochanowka records from 1840.

Tarnowskie Gory.  25 km NW of Katowice.  Records from 1641.  I did not check these microfilms.  I noticed the data by typing “Gwozdz” into [IGI, Germany].  There are several Gwozdz people from 1723, with no source references.  The data is obviously from the microfilms.  Tarnowskie Gory is also indexed under Tarnowitz:  Germany, Prussia, Schlesien Province.

Paszczyna.  23 km SE of WG.  Records from 1634 with Lubzina, independent from 1786.  Continuous Gwozdz records from 1753.  This is not the same as Pszczyna.

Wadowice Gorne.  My ancestral parish.  Records from 1777.  Three Gwozdz records 1778.  About 10 Gwozdz families, with continuous records.  The village of Wampierzow has separate records, including Gwozdz families.  The villages of Wadowice Gorne, Wadowice Dolne, and Wola Wadowska are not separated in the oldest records.  (In most parishes the exact village is indicated for some records.)  Some of the Gwozdz people in this parish changed their name to Knap;  their records use either or both names.  It is not clear if all the Knap people were once Gwozdz.  What do you think - maybe the name Knap was easier for doing business with the Austrians?  My family line did not change (obviously).  I visited this parish a few times, and I studied the 19th century records that have not been microfilmed.

Laczki Brzeskie.  12 km SE of WG.  Records from 1786.  First Gwozdz record is Simon Gozdz, father at a birth in 1786.  This parish, founded in 1957, used to be part of the Przeclaw parish, mentioned above.  Laczki is one of the villages identified as a Gwozdz village in the 1660’s records from Przeclaw.  Laczki has plenty Gwozdz records;  it should be possible to make a few Gwozdz descendancies starting before 1800.

Mielec.  10 km E of WG.  Records from 1785.  Only one Gwozdziowski marriage, 1788.  All marriages checked 1785-1800.  There was only one church back then;  today the city has 4 parishes.  I studied Mielec because it is the largest city in the WG region of my ancestors.  I noticed that the family names in Mielec as a whole then were different than the names in WG and villages to the south and west.  I speculate that people did not move much over the river between Mielec and WG.

Zgorsko.  The parish closest to WG, just to the south.  Records from 1799, with a few Gwozdz families from the beginning.  Continuous Gwozdz records.  I visited;  the parish has 19th century records not microfilmed.

Brzeznica.  21 km SE of WG.  Records from 1821.  Continuous Gwozdz records.  There was no parish here in the 18th century.  I have not figured out where the older records are;  they may be in more than one neighboring parish.  The Gwozdz grandfather of Jarvis Gust (see Lubzina) was born here, but his family apparently moved in and out.  I visited this parish, which has 19th century records not microfilmed.

Pustkow.  17 km SE of WG.  Recent modern parish, with earliest records probably split among multiple parishes, not figured out.  It seems Pustkow was called Wolka Pustkowska back then, with Gwozdz records in Lubzina parish microfilms from 1826.

Zasow.  17 km S of WG.  I found Gwozdz microfilm transcription data at [], for the parish of Zasow.  Five Gwozdz marriages 1811 to 1857.  By the way, that spuscizna web site has excellent photos and other information for more than 100 parishes in southeast Poland.  Zasow is the only parish I could find at this site with transcriptions from the microfilms, apparently because Zasow is the ancestral parish of the webmaster.

Polish Towns That Probably Have Late 19th Century Gwozdz People

I suppose there must have been hundreds of towns with Gwozdz inhabitants at the end of the 19th century, but I really don’t know how many.

One way to get a partial list of 19th century towns would be to check modern phone directories for Polish towns with lots of Gwozdz names, particularly in those counties in my table of counties with many Gwozdz people.

Another way to get a partial list of towns would be to look at the US immigration data, where town of origin is usually listed.  Lots of Poles moved to the US at the end of the 19th century. provides 329 hits for “Gwozdz” in their data base of immigration records (in 2012), but I have studied these.  In addition, our name is often misspelled as Gwuzdz, Gwozd, etc, but when I turned on the “soundex” option at to include spelling variations, thousands of hits came up;  most of these are not related to Gwozdz.

Over the years I contacted a few Gwozdz people not related to me.  In recent years I started sending emails when I see Gwozdz genealogy data on the web, and about 5 have responded.  About 20 more people with Gwozdz Polish ancestors have seen my site and contacted me by email.  All told I have about 40 Gwozdz or Gwozdz descendant contacts.  Most of these have not figured out the home town of their Gwozdz ancestor.  Many are from the same town as another contact.  I respond to all, but I do not have time to help.  I worked on the leads that looked like my distant relatives.  Three turned out to be distant relatives of mine, one a 6th cousin.

The towns that I know have Gwozdz microfilm data are listed in the previous topic.  I suppose most if not all of those had Gwozdz in the late 19th century, although late 19th century microfilms are not as plentiful as mid 19th century.

The top of the previous topic has general comments and web links for maps  and microfilms.

Send me an email to add your ancestral Gwozdz town to this list.  If your town is already here, let me know if I should forward your email to my previous contact.

Bojszowy.  See Bojszowy Nowe.

Bojszowy Nowe.  24 km south of Katowice.  14 km NE of Pszczyna.  I made contact on the web.  [].  A descendancy for Marcin Gwozdz, whose son Pawel Gwozdz is listed as born 13 Nov 1906 in Bojszowy Nowe, so I presume Marcin was born there about 1875.  I checked the LDS index and noticed that there are microfilms for Bojszowy parish, from 1824.  The webmaster, descendant of Marcin, responded to my email and informed me that the neighboring parishes of Wola and Miedzna also have lots of Gwozdz people.  Miedzna has microfilms from 1817, but Wola, a newer parish, does not.  I understand that the Bojszowy Nowe parish was founded in 1980, south of Bojszowy, so we do not know if Marcin went to church in Bojszowy or Miedzna or somewhere else.

Kielczyna.  See Wola Malkowska.

Koscielniki.  15 km NE of Krakow.  I  worked on the family tree of a family from Koscielniki because I thought we were related.  We are not.  No microfilms available.  This Gwozdz family was in the military, moving a lot.  I visited the Koscielniki church;  the priest quickly found the marriage of the Gwozdz grandfather of this family in the late 19th century records.  He was born 1883 in Kidalowice, a village in the parish at Jaroslaw, which is 50 km E of Rzeszow.  Jaroslaw has lots of microfilms, but none 1883.  I checked 3 birth record microfilms, for years just before the 1883 birth grandfather.  I found no Gwozdz names.  These are indexed as Austrian Army records.  That just means the great grandfather was not having children just before 1883, when he was at the military base in Jaroslaw.  As I type this paragraph in 2007, I checked the LDS index, and I see that there is a new film with 1883 records, but I’m no rush to check this film, because these people are not my family, and they probably moved into the military base from somewhere else.

Miedzna.  See Bojszowy Nowe.

Pszczyna.  30 km due south of Katowice.  A Gwozdz family in Gdansk emailed me.  Their ancestor lived in Pszczyna.  We met in Poland for a visit.  Microfilms are available for Pszczyna, from 1794.  This is not the same as Paszczyna.

Wola.  See Bojszowy Nowe.

Wola Malkowska.  110 km NE of Krakow.  11 km N of Staszow.  A Gwozdz noticed my web site and made email contact.  His Gwozdz ancestors came from the village of Wola Malkowska, parish of Kielczyna, 5 km to the east;  microfilms are available 1867-1884.

How Many People in the World Have the Name Gwozdz?

My rough estimate is 11 thousand, as follows:

The Wikipedia article on Poland, [] (2016), gives the population of Poland as 38.5 million in 2016.  Population growth since 2000 is very small, about 2%.

“Polonia” is the word for Polish diaspora - people of Polish ancestry living outside Poland.  The Wikipedia article on Polish diaspora, [] (2016), estimates there are 20 million of us.  That implies roughly 1/3 of Polish people are Polonia.

However, that 20 million includes people of “partial Polish heritage”.  Because of intermarriage, Polish family names should be diluted among Polonia to the extent of intermarriage.  I’ll divide by 2 for number of Polonia with Polish family names.

My justification for this divisor of 2 is discussed at the bottom of this topic.  This division of reported Polonia by 2 is the largest uncertainty in my calculation in this topic.  That divisor of 2 includes other adjustments, not only the adjustment for intermarriage.

That 38.5 million includes people living in Poland who are not of Polish ancestry.  That Poland wiki article gives 37.0 million people who declared themselves Polish in the 2002 Poland census, but another 775 thousand did not declare nationality, and surely many of them are Polish.  I do not reduce the Polish population for foreigners or for partial Polish heritage (intermarriage with foreigners in Poland), because I am using the family names for all of Poland in this calculation.

% Polonia = (20 / 2) / (38.5 + 20/2) = 10 / 48.5 = 20.6%.

According to Rymut, about 8.8 thousand people in Poland spell their name Gwozdz with various accents and minor spelling variations, using data from the 2000 census.

Gwozdz including Polonia = 8.8 * 1.206 = 10.61 thousand.

Adding 2% for population growth since 2000 and rounding up,  I calculate very roughly:

11 thousand Gwozdz people worldwide.

This is my 2016 update, which is the same result as my 2003 update to this web page.

This does not include other Gwozdz-like Slavic names from other nationalities.

This estimate is intended to be the number of people who consider their name equivalent to Gwozdz.  There are many variants, considered related but distinct names.  The most common variant, Gwozdzik, however, has only 476 people in Poland.  The close variants as a whole probably add only about 10%, another thousand or so.  One possible exception that I know of:  about 3000 people named Gozdz are not included in this estimate.

Many of the variant names no doubt descend recently from a Gwozdz family.  Conversely, many of the Gwozdz count might be people whose recent ancestors carried a variant like Gwozdzik and changed to Gwozdz.  I bet most of the Gwozdz people who change their name choose a simpler name, unrelated.  I bet more people change away from Gwozdz than toward Gwozdz.  There is no need to adjust the estimate in Poland for name changes, since I am estimating how many people today use the name.  Insofar as diaspora are probably more likely to change their name, my divisor of 2 includes this (discussed below).

More than 40 thousand people should be interested in this web site, because everyone has 4 grandparents.  11 times 4 means roughly 44 thousand people have a grandparent named Gwozdz.

That Polish_diaspora wiki article estimates 10 million Americans.  The Wikipedia article [] (2016) estimates a more precise 9.5 million “Americans who have total or partial Polish heritage.”  Again dividing by 2 gives:

Gwozdz in the USA = 11,000 * (9.5 / 2) / (38.5 + 20/2) = 1,077.  I calculated 1,137 above a different way, directly from the US census.  1,137 is a better number.  I calculated 1,077 here as a way to double check my calculation of 11 thousand Gwozdz worldwide.

Divisor of 2 Adjustment:  The largest uncertainty in my calculation worldwide is the divisor of 2 adjustment for Polonia as reported in the web sites.  Actually, I worked backwards, and figured a divisor of 1.868 to make this calculation here come out exactly 1,137 as above.  I then used a divisor of roughly 2 in this topic to avoid seeming silly.

This divisor of 2 does not apply to the population of Poland because I am using the family names for all of Poland in this calculation.  The issue here is adjustment of Polonia for the calculation of number of Gwozdz people worldwide.  For US Gwozdz people, US census data is best.  This divisor has no effect on the accuracy of my rough estimate of roughly a thousand Gwozdz in the US.

When I use a divisor of 1.0 (equivalent to no division - no reduction of Polonia), Gwozdz worldwide comes out 12 thousand.  When I use a divisor of 4.0 (too much reduction of Polonia) Gwozdz worldwide come out 10 thousand.  So the uncertainty in the 11 thousand estimate of Gwozdz worldwide seems to be within a range of 10%.

This divisor of 2 adjusts for multiple uncertainties.  The 4 that I consider most important are discussed in turn in the following 4 paragraphs:

1. “Partial heritage” meaning Polonia with mixed nationality, is mentioned above.  It seems to me this is the largest part of my adjustment, and the largest single source of uncertainty in my calculation of World Wide Gwozdz people.  This adjustment may vary among Polonia moving to different places insofar as intermarriage frequency may differ.

2. Name changing among Polonia.  This issue 2 adds to issue 1, also reducing Polish names among Polonia, increasing the adjustment divisor.  I suppose, since Gwozdz is a difficult name outside Slavic countries,  Gwozdz gets changed more often than most names, so the divisor for Gwozdz is probably greater than the divisor for most other names.  This may vary among Polonia moving to different places.

3. Issues with “Poland”:  There is confusion determining who is Polish, due to variations of the border of Poland over the centuries, and due to the fact that Poland did not exist as a country for more than 100 years, and due to groups whose various individuals may or may not consider themselves Polish - for example Jews.  I discuss this issue in another of my web pages:


4. Region of Poland:  Gwozdz is a name confined mostly to south Poland.  I do not know if Polonia from south Poland (Austria during the 19th century) are more numerous or less numerous than from north Poland (Russia) or from west Poland (Prussia).

I am aware that this kind of calculation can be done for the worldwide population of any family name.  I am not simply recommending reduction of Polonia by a divisor of 2, although I expect 2 would work as a quick calculation for most names.  My recommendation is to calculate the number of people with a particular name in the US from the US census (or in another country of interest) as above, then adjust the divisor to produce roughly the same number as in this topic, then use roughly that same divisor for Polonia to calculate worldwide.

Some cases might have a very different divisor adjustment.  I briefly commented on differences in the paragraphs above for each of the 4 issues.

I have never seen a publication or web page with this method.

Informed Speculation About Polish Family Names

If you are still reading this document in order, you probably noticed a gradual transition from facts and data toward informed speculation.  That’s the style.  The remainder of this document continues to become more speculative, albeit with reasonable reasons given for the speculation.

Also, you may have noticed that the general method of the last topic could be applied to most Polish family names, not just Gwozdz.  The same is true with the remainder of this document.

Can Most Gwozdz People Expect to Find Records of Their Ancestors?

Yes.  Most parishes in southern Poland have 19th century vital records.  Once you determine the parish of your Gwozdz ancestor, chances are you should be able to find birth, marriage, and death records for the ancestral family.

Check out [Polish genealogy] web sites for tips on finding ancestors, and for how to find the family parish using recent records, such as US marriage records and US immigration records.  Such web sites also have instructions for writing letters to Poland.

I have another web help site for details concerning the use of the [LDS Microfilms].  I estimate that microfilms are available for more than half the parishes in southern Poland.  For those parishes with microfilms are available, I estimate that more than half are good enough to trace ancestral families all the way back to the 18th century (late 1700’s).

It takes more work to write letters to the Polish parish, or to visit.  With that extra effort, almost all Gwozdz people should be able to find at least some ancestral data.

In that other web help site, I provide rough estimates of what [percent] of Polish parishes have microfilmed records.  In the southern Gwozdz region, the percent of parishes with microfilms is higher than in the north.  Also, people changed parishes less often in the south, so it’s easier in the south to create a family tree.  Here in this topic I provide a little more detail on those rough estimates for southern Poland.  These estimates are based on my personal research experience.  I did not take the trouble to do a proper statistical analysis, so please remember this topic is estimates.

I explained above that 1777 to 1787 are special years.  Many south Poland microfilm records start in a year between 1777 and 1787.  The chances are slim for finding records before 1777.  However, if you find the death record of an ancestor who died in the late 18th century, it will give his age, so technically you have a record to the early 18th century.

Even with good records, not all family trees can be documented.  Some pages are missing.  Some books are missing.  Some male descendants get lost from the documents.  Some males show up in the documents without connections.  For these reasons, working backwards, some family branches do not connect back to the oldest available records.  This does not happen too often in south Poland, in my experience.  I am only trying to come up with approximate estimates, so I do not need much of an adjustment for this.  Earlier, I said “more than half” of the parishes have 19th century records, then I said “more than half” of those have good records back to the late 1780’s.  For my rough estimate for tracing your ancestors then, I’ll drop the “more than” and say the odds are about 1/4th to trace a modern Gwozdz family back to 1780’s microfilm records.

My research is biased toward the region of my ancestors.  A book is available, also on CD, from [PGSA], with the 1772 Parishes of Poland, alphabetically listed, and also marked on maps.  I tested map page XV, which includes the region around Katowice and Krakow, where I figure most Gwozdz families seem to have originated.  I do not know why Katowice itself is not listed.  I arbitrarily picked 10 parish names from that map in the region within 75 km of modern Katowice.  I typed those 10 names into the [LDS Place Search].  Four of the 10 do not have microfilms available, consistent with my estimate more than half do.  Of the 6 with microfilms, 3 start between 1830 and 1842.  The other 3 start in 1650, 1718, and 1735, with what look like more or less continuous records through the 19th century.  This small sample test is consistent with my experience that more than 1/4th of parishes have good microfilm records going back to the late 18th century.

As a case study example, let me explain what I found for my family.  I hope this example motivates some of you to search for your ancestors:  My paternal grandparents came from 2 different parishes in south Poland.  My maternal grandparents came from 2 different parishes in north Poland.  My impression from other studies is that my family results are typical of what is available in Poland, north and south.

I found the names of all 16 of my great-great grandparents.  Grandparents of my grandparents, 4 times 4.  Twelve are from microfilms.  There are no microfilms for the parish of my paternal grandmother from the south, but my late cousin, who writes fluent Polish, got those 4 names by writing to the parish in Poland.  The birth record books for both my grandfathers are missing, but I was able to find birth records for known siblings, which name their parents (and also grandparents in the south).

Previous generation:  I found the names of 24 of my 32 three-great grandparents, who were born in Poland between 1765 and 1802.  I found all 8 for my paternal grandfather from the south on microfilm;  only one moved in from another parish, but that parish has microfilms, too.  I taught myself to read Polish well enough to visit that parish of my paternal grandmother.    (It is difficult to get permission to study records, but my Polish 2nd cousin had cooked meals for the pastor when he was without a housekeeper, so I had a nice introduction).  I found that 4 of my ancestors all lived in that parish, and 4 lived in the adjacent parish, which also has no microfilms but which also has a pastor that let me study the records.  My maternal ancestors from the north changed parishes, so I had to study 5 parishes.  None of those parishes have records, but microfilms from the diocese archive have some records for 3 of them.  I found 8 of the 16 in these microfilms.  Two of those 8 are only a first name of a wife, with no maiden name or year.  I recently found what may be 2 more for this list, in microfilms for a 6th parish, where I found microfilmed birth records for two girls with the same name as my great-great grandmother, but I have not yet found any evidence that one of the pairs of parents go onto my family tree.

Previous generation:  I found the names of 35 of my 64 four-great grandparents, who were born in Poland between 1733 and 1770.  Grandparents of the grandparents of my grandparents = 4 times 4 times 4.  Two are only a first name of a wife.  Seven have no birth or death date.  Paternal grandfather’s ancestors:  15 of the 16, from the microfilms of those 2 parishes, but 4 of the 15 are highly speculative;  2 are based only on common house number, which is poor evidence;  2 are process of elimination where multiple individuals have the same name as my ancestor so I had to study multiple families for uncertain evidence.  Paternal grandmother’s ancestors:  15 of the 16, from the books at those 2 parishes mentioned above.  Maternal grandparent ancestors from the north;  from microfilm:  only 5 of the 32, although I may find 4 more if that recent lead pans out.

Previous generation:  I found the names of 16 of my 128 five-great grandparents, who were born in Poland in the early 18th century.  All 16 are from the microfilms.  8 from my paternal grandfather’s parish in the south and 8 from my maternal grandmother’s parish in the north.  Birth and death years are available from death records, but for only 3 in the south, and one of those is highly speculative, based on a 75 year old Gwozdz widow who died 1787 (first year of death records) in the house number where my 3-great grandfather Gwozdz  was having children, so I guess she might be his grandmother but of course she could be an aunt or great aunt.

Previous generation:  I found no six-great grandparent names.

I now have a total of 35 family names in my family tree.  However, it is not correct to say I traced 35 families, because many of those are just the maiden name of a wife with no connection to other people in that parish with the same name.  Actually, I have 33 names, with 2 duplicates, but no evidence that those duplicates are relatives.  Someday, if I try to trace the maiden name families of my 18th century tree forward to the present time, I expect to succeed on “more than half” of them, based on the estimate that I gave above.

Here is a rare tidbit for my Gwozdz 3-great grandfather.  His marriage is missing from the record book where it should be.  I was able to prove that a whole year is missing.  The book is a copy.  The original is lost.  There were about 2 pages per year of marriages.  I figure the scribe accidentally turned two pages at once while copying, jumping from mid November 1793 to mid November 1794.  I could tell because marriage dates suddenly increased by 6 instead of 7 for mostly Sunday marriage dates.

In a search for distant cousins, I helped a few individuals who provided me with the names of their ancestors from my Gwozdz ancestral parish, and from neighboring parishes.  Again, my experience is that more than half of the family lines that I worked on connected back to the late 1780’s.  I found a 6th cousin this way.  Actually, he found me on the web, and I documented the family connection.  By the way, we both have Gwozdz ancestors in that parish, but there was no Gwozdz connection in the records.  One of our other branches connected in the mid 18th century.  It sounds like luck, but there are so many families in both our trees that I figure a family relation between any two people with ancestors from that parish in the 18th century is about 50-50 probability.

Conclusion:  About 1/4th of researchers with a parish name and an identified Gwozdz ancestor from the 19th century should be able to trace that ancestor’s Gwozdz family in the microfilms back to the middle of 18th century.  Those who cannot trace a family through the microfilms might have luck by contacting the parish.

Once a family tree gets started, by the way, there quickly become several branches in the same parish, so the probability of documenting at least one of the branches back to the oldest parish records is almost certain.  That 1/4th probability was restricted to the consideration of a single branch, like Gwozdz, when it is not known yet if microfilms are even available.

Do Most Parishes in South Poland Have Gwozdz People around 1800?

No.  For years between 1787 and 1820, I found Gwozdz microfilm records in about 1/5 of the parish records that I checked.  My research is focused on the region around Wadowice Gorne, where my grandfather was born, which is on the northeast edge of the region where most Gwozdz people in Poland live today.  So my results are not exactly representative of the region of highest Gwozdz density near Katowice and Krakow, where we might expect Gwozdz people in a higher percent of the parishes.  My research is focused on parishes where I had prior evidence of Gwozdz inhabitants, so I suppose that biases my 1/5 finding toward the high side.  On the other hand, I only sampled the records for adjacent parishes;  surely I missed some Gwozdz records in some of those parishes;  that biases by 1/5 finding toward the low side.

My mother’s parents are from the region northeast of Warsaw, so I have also studied many microfilm records from the north.  I never found any Gwozdz records in the north.  That reinforces my conclusion that Gwozdz is a southern Poland name.  I have spotted only one Gwozdz variant in the north:  an 1805 birth record in Gasewo with the name Gwozdziewski.  However, that record is unusual, because the record mentions that the family also used the alias Szybonski.  Film 1417676, Item 2.  I would expect to find a Russianized variant like Gwozdziewicz in the north, but I have not spotted such a one in the microfilms yet.

Tentative Opinion:  I expect that the region around Katowice and Krakow in the southeast of Poland has microfilm Gwozdz records in more than 1/5 of the parishes that have microfilm records.  I expect microfilm Gwozdz records for somewhat less than 1/5 of parishes throughout southern Poland.  I expect Gwozdz type names to appear in very few parish record microfilms in the North.

Solid Conclusion:  The Gwozdz family name, though not generally common, was used in many villages of southern Poland by the end of the 18th century.

Multiple Originations of the Name Gwozdz

This topic applies to most family names, not just Gwozdz.  It is common for genealogists to believe that their family name originated only once, and that all people with that name are related.  That may be true for some very rare family names, but it is generally not correct, so I am summarizing here my evidence that the name Gwozdz originated independently many times.  If you already agree with this you can skip this topic.

A number of times in this document I already made comments about evidence that the name originated multiple times.

Roughly Eleven Thousand Gwozdz worldwide.  The name is not uncommon in the south of Poland.  It does not seem reasonable to assume we are all male line descendants from a unique male who took this name.  I doubt the name originated less than 10 times although I cannot prove that.

About 35 Gwozdz-like names of Towns and Villages in Poland.  Listed in the Gazetteer published in the late 19th century.  Mostly in southern Poland.  Something about the word Gwozdz apparently encouraged people to use the word often as a name of a place.  I suggest this may have been due to the archaic meaning “forest”.  Maybe in south Poland the family name Gwozdz was like the family name Forest in English.  Also, it makes sense that villages tend to be named after the local landlord and landlords tend to take the name of their local village.

Y-DNA.  I have done lots of [research on Y-DNA].  I have looked at the results of many [family name Y-DNA projects].  Those with lots of Y-DNA data all have many divisions of their members, where the divisions are very distant branches of the Y-DNA tree, typically separated from each other by thousands of years - often more than 10,000 years.  So Y-DNA proves that family names with lots of Y-DNA data do not all descend from one man who took that name less than two thousand years ago.  In my Gwozdz project I so far have Y-DNA data from only one Gwozdz who is not a cousin of mine, and we are on very distant branches, obviously not descended from the same origination.

Y-DNA may not verify genealogy records because of non paternal events [NPE], such as adoptions, illegitimacies, cuckoldry, etc.  NPEs add apparent Y-DNA branches with the same family name;  I say “apparent” because genealogist may consider these to be the same branch if family records place them together.

Meaning of the name Gwozdz.  In that topic I discuss multiple possible meanings, in view of my opinion of multiple independent originations.

Extinction.  Most family names go extinct due to a lack of male descendants.  So the number of originations of the name Gwozdz are surely larger than the number of Gwozdz male lines existing today.  (During rapid population growth the probability of a new family name surviving is increased;  Poland’s population had grown rapidly during the past few centuries.  So in recent centuries, perhaps is it more accurate to say many, not most, Gwozdz male lines went extinct.)  Many people are surprised by the assertion that most family names become extinct;  the reason is the same as for Y-DNA;  I give a brief [review of the reason in one of my Y-DNA web pages].

Name Changing.  In previous centuries, families changed their name more often than in the past 100 years.  I found Gwozdz people around 1800 who changed their name to Knap.  I also found another name change in my ancestry around 1800.  Since Gwozdz is a difficult name outside Slavic countries I suppose more Polonia changed away from Gwozdz than to it, but I wonder if maybe the name Gwozdz was an attractive surname in southern Poland during the 16th and 17th centuries.  That Gwozdz to Knap change, during the Austrian years, is a hint that people changed away from names like Gwozdz that were difficult for Austrians.  Similarly, I have 2nd cousins in the US who changed Gwozdz to Gust and I have records of Gwozdz people changing to Nail.
