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.

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.

  • Slovene · English 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.

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.

Where it is borne, and where a record names it

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 5 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. 11 people in 2 of Belgium's 565 communes, counted by Statbel. The biggest is Beringen with 6. 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

Whose archive to write to

153,360 of 528,875 volumes held for United States of America overlap the 1790s, 1820s, 1840s, 1860s, 1920s, 1950s, 1970s and 1980s — the decades Čok is attested here. Too many to list, and this atlas does not know whether any one of them names Čok. The commonest kinds: Probate, land and notarial, Civil registration and vital records, Immigration and emigration, Church and parish registers.

Poland

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

Whose archive to write to

This atlas has no birth-year evidence for Čok in Poland, so it cannot narrow Poland's 15,686 volumes by date — see Poland's own page for all of it.

Whose archive to write to

38 of 24,426 volumes held for Belgium overlap the 1510s — the decades Čok is attested here. None is known to name Čok: a volume overlapping these years is a document from the right place and time, not a confirmed match. Worth an afternoon.

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 Čok in Denmark, so it cannot narrow Denmark's 4,099 volumes by date — see Denmark's own page for all of it.

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.
