Longa

Longa. Attested in Spain, France, Poland, Italy, Belgium, borne by about 1,227 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.

Longy

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.

Llonga

Only sounds alike

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

It is also the name of a place

Where those places are. A dot is a settlement whose name is this surname, sized by its population — not a claim that anybody of the name lives there. Phonetic neighbours are listed below but not drawn: putting a machine's guess on the ground would dress it up as geography.

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

Attested in 5 countries: Spain, France, Poland, Italy, BelgiumBelgium — 6 peopleItaly — 132 peoplePoland — 159 peopleFrance — 245 peopleSpain — 685 people
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 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. 6 people in 1 of Belgium's 565 communes, counted by Statbel. The biggest is Herve 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.

Whose archive to write to

14 of 24,426 volumes held for Belgium overlap the 1950s and 1960s — the decades Longa is attested here. None is known to name Longa: a volume overlapping these years is a document from the right place and time, not a confirmed match. Worth an afternoon.

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.
