    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

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 4 countries: Spain, Poland, Denmark, IrelandDenmark — attested, not countedIreland — attested, not countedPoland — 2 peopleSpain — 38 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. 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 4 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.

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 O'Shaughnessy. The commonest kinds: Newspapers and gazettes. See everything this atlas holds for Ireland →

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.
