Kačič

Kačič. Attested in Slovenia, United States of America, Belgium, borne by about 327 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.

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 · Serbo-Croatian 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.

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. Blank is not absence. This draws the 3 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. 12 people in 2 of Belgium's 565 communes, counted by Statbel. The biggest is Binche 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.

Slovenia

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

Whose archive to write to

28 of 1,585 volumes held for Slovenia overlap the 1880s, 1910s and 1960s — the decades Kačič is attested here. None is known to name Kačič: a volume overlapping these years is a document from the right place and time, not a confirmed match. Worth an afternoon.

United States of America

Whose archive to write to

4,105 of 528,875 volumes held for United States of America overlap the 1970s — the decades Kačič is attested here. Too many to list, and this atlas does not know whether any one of them names Kačič. The commonest kinds: Probate, land and notarial, Civil registration and vital records, Church and parish registers, Cemeteries and burials.

Belgium

12 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 Kačič in Belgium, so it cannot narrow Belgium's 24,426 volumes by date — see Belgium'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.
