Kowalewski

Kowalewski. Attested in Poland, United States of America, France, Spain, Belgium, Denmark, borne by about 14,349 people in the registers this map holds.

The same name, inflected

A rule of the language rather than an opinion. Polish makes Kowalski and Kowalska of one surname.

Kowalewska

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.

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.

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.

  • Polish what the English entry says it is from
  • English · Polish 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.

Where it came from

No place of this name is in the gazetteer, so this map says nothing about where the name came from. Search a surname anywhere else and you will be told an origin — that it is Latin, or Italian, or means «joyful». That is etymology, it is usually unsourced, and it is a different question from the one answered here.

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 6 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. 17 people in 2 of Belgium's 565 communes, counted by Statbel. The biggest is Genk with 9. 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.

Too many to list, and this atlas does not know whether any one of them names Kowalewski.

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.

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.
