Clan Rising

Irish Clan Finder

Enter your surname and trace it to the Irish clan or sept it descends from — the Gaelic kindreds, the Norman-Irish houses, and the names the diaspora carried across the world.

Name

Free, instant, no account — every result is a documented family record.

Ireland wrote surnames earlier than almost anywhere in Europe — the Ó and Mac prefixes marked descent from a named ancestor while most of the continent was still on single names. The finder matches your spelling and its variants against the documented Irish records: prefix dropped or restored, O' or Ó, anglicised or Gaelic.

Each record documents where the name held territory, what it means and who it descends from, the family's stories, and the famous bearers who carried it — the pre-emigration home of the name, which is the part a famine-era or later crossing usually erased from family memory.

The Irish shelf currently documents 56 names, and it grows continuously.

Frequently asked

How do I find my Irish clan?

Type the surname into the finder. It matches against the documented Irish records in the atlas — Gaelic clans and septs and the Norman-Irish houses — including spelling variants, and returns the full record: origin, territory, meaning and stories.

Are Irish family names clans or septs?

Both words are used. The great kindreds — O'Neill, O'Brien, MacCarthy — were clans in the full political sense; sept usually describes a branch or a family attached to a greater house. The atlas documents each surname as its own record and lets the history say which shape the name took.

My name lost its O' — is it still the same family?

Almost always, yes. Dropping the O and Mac prefixes was widespread under English administration, and many families restored them later. Connor and O'Connor, Brien and O'Brien resolve to the same documented line, and the record lists the variants it covers.

Is my surname Irish or Scottish?

Many Gaelic names genuinely span both shores — the two Gaelic worlds shared a sea, a language and centuries of movement. The finder resolves your name to its documented home, and where a name has real presence on both sides the record says so and cross-links the other side of the story.
