Tamás

Tamás. Attested in United States of America, Spain, France, Poland, Belgium, Slovenia, Italy, Denmark, borne by about 1,402 people in the registers this map holds.

The same name, spelt two ways

One systematic substitution — s for z, w for v, ch for h — where BOTH spellings are independently attested surnames. Kosina and Kozina are one man in two clerks' handwriting. Stronger than sounding alike, weaker than somebody having checked.

Only sounds alike

An algorithm's guess. Useful for casting a net, and not evidence.

What Wikidata says this name is

Copied from Wikidata, not worked out here. It is crowd-sourced and wrong in places, which is why the item is linked below rather than the claim simply repeated.

  • Romanian · Hungarian the language of the name

    Which is not where a family is from. A Polish surname can be borne by people whose forebears never saw Poland, and often is.

What Wiktionary says this name is

Copied from the surname template on Wiktionary, not worked out here, and not from its etymology prose. Anyone may edit it; the page and the revision it was read at are linked below.

  • Hungarian what the Romanian entry says it is from
  • Hungarian what the English entry says it is from
  • Romanian · English recorded as a surname in these languages

    A language here is the language of the NAME, not a country a family came from — the same caveat the Wikidata section carries, and worth repeating rather than assumed read.

It is also the name of a place

This is as close to an origin as this map will go. A surname that is also a place name often came from it — and often did not: plenty are occupations or patronymics that happen to collide with a place, and plenty of places are named after a family rather than the other way round. It is a fact with a source, which is more than an etymology page offers.

A dot is a country, not a place. It sits at the country's centre because a national register counts a country; nothing here says where in it these people are. A hollow ring is attested but not counted — Denmark publishes which surnames exist and not how many carry each, and a family archive finds a name without counting heads. Sizing those by a number nobody published would invent it. Blank is not absence. This draws the 8 countries where the eleven registers and eight archives behind this atlas attest the name. Most of the world has no surname register this project can read, and the ones that do and will not are listed with the reason.
Belgium, by commune. 18 people in 3 of Belgium's 565 communes, counted by Statbel. The biggest is Merelbeke-Melle with 7. This is the only country here that can be drawn this way — every other register counts a country and stops, so a blank elsewhere is a gap in what states publish, not in the name.

Country by country

Each country below can carry up to three different kinds of evidence, and none of them is the same claim. A register is a head-count — a state counted these people. A record is one document naming the surname on that ground, narrower evidence and often much older. And a volume overlapping these dates is a document from the right place and years — never a document known to name this surname. None of the three ever means the name exists in that country and nowhere else, or that it exists nowhere but here.

United States of America

571 Borne — a state counted them — Frequently Occurring Surnames from the 2010 Census; Frequently Occurring Surnames from the 2000 Census.

Whose archive to write to

50,933 of 528,875 volumes held for United States of America overlap the 1880s, 1970s and 1980s — the decades Tamás is attested here. Too many to list, and this atlas does not know whether any one of them names Tamás. The commonest kinds: Probate, land and notarial, Civil registration and vital records, Immigration and emigration, Church and parish registers.

Spain

France

153 Borne — a state counted them — Fichier des noms de famille 1891–2000 (INSEE, fichier national).

Whose archive to write to

5 of 1,513 volumes held for France overlap the 1910s, 1950s and 1980s — the decades Tamás is attested here. None is known to name Tamás: a volume overlapping these years is a document from the right place and time, not a confirmed match. Worth an afternoon.

Poland

127 Borne — a state counted them — Nazwiska występujące w rejestrze PESEL (z uwzględnieniem osób zmarłych).

Whose archive to write to

2,223 of 15,686 volumes held for Poland overlap the 1900s — the decades Tamás is attested here. Too many to list, and this atlas does not know whether any one of them names Tamás. The commonest kinds: Church and parish registers, Civil registration and vital records, Cemeteries and burials. See everything this atlas holds for Poland →

Belgium

18 Borne — a state counted them — Family names by municipality, 1 January 2026 (Statbel, TA_POP_LST_2026).

Whose archive to write to

This atlas has no birth-year evidence for Tamás in Belgium, so it cannot narrow Belgium's 24,426 volumes by date — see Belgium's own page for all of it.

Slovenia

12 Borne — a state counted them — Family names, Slovenia, 2026 (SURS tables 05X1015S–05X1018S).

Whose archive to write to
Attested here, and nothing that survives covers those years

Tamás is attested in Slovenia in the 1970s. Not one of the 1,585 volumes this atlas holds for Slovenia covers those years — worth knowing before an afternoon is spent on Slovenia's shelf rather than after.

Italy

4 Borne — a state counted them — Italian comuni publishing their residents' surnames as open data, indexed by the national catalogue dati.gov.it..

Whose archive to write to

50,540 of 1,288,913 volumes held for Italy overlap the 1920s — the decades Tamás is attested here. Too many to list, and this atlas does not know whether any one of them names Tamás. The commonest kinds: Civil registration and vital records, Church and parish registers. See everything this atlas holds for Italy →

Denmark

Borne — a state counted them — Navne registreret i Danmark, January 2020 (Danmarks Statistik, republished by Digitaliseringsstyrelsen).

Whose archive to write to

This atlas has no birth-year evidence for Tamás in Denmark, so it cannot narrow Denmark's 4,099 volumes by date — see Denmark's own page for all of it.

When it was being born, in France

INSEE counts births by surname and decade from the état civil, 1891 to 2000 — the only dated evidence in this dataset. A name that starts at zero and climbs arrived; a name that falls to nothing left, died out, or emigrated, and the decade it stops is the decade to stop searching. It counts births registered in France, so a family that emigrated in 1900 simply stops appearing, which is information rather than a defect. This name's first French births fall in 1901–1910 and its last in 1991–2000.

Whose archive held that ground, and when

Every surname site can tell you a name is common somewhere. This one also knows which filing system held that ground in which years — and those are the two halves of one question: my people were called this, they were there, so who has the paper, and for which century. A name in Croatia before 1881 may sit in a military series and not a county one; a name in the Netherlands before 1811 has no civil record at all, only a baptism.

This is about the ground, not about your family. A register counting a name in a country says nothing about which village. And these are the pieces of a country this atlas has drawn, which in a large one may be a corner of it — Acadia reaches into Maine and is not a statement about the United States, and Bohemia's ground crosses into Poland. Each region's own page says which ground it covers. Where a country is missing below, nothing covers it yet.

No record region is drawn yet for Spain — which is a gap in this atlas and not a statement about that country.
