Adamov

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.

• Bulgarian · Serbian · Ukrainian · Russian 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.

• Bulgarian what the Romanian entry says it is from
• Romanian · Slovak 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.

Where it is borne, and where a record names it

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.

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.
