Quick answer: the Irish surname Collins comes from Ó Coileáin, “descendant of Coileán.” Patrick Woulfe records an Uí Fhidhgheinte family in County Limerick whose main body settled in West Cork after 1178, creating the regional association that remains central to the Irish Collins story.

What does Collins mean in Irish?
Woulfe gives the Irish form as Ó Coileáin. The surname is patronymic: it preserves descent from an ancestor named Coileán. Woulfe glosses that personal name as “whelp,” the Irish word for a young hound, which served as an old and honored personal name.
Where did the Irish Collins family come from?
The best-documented Irish tradition begins in Uí Chonaill Gabhra, later Connello, in County Limerick. Woulfe records that the family was expelled in 1178 and that its main body moved south into West Cork. That movement links the name to two important landscapes: its earlier Limerick territory and the Cork districts where Collins families became firmly established.
West Cork already had a native family, Ó Cuilleáin, whose name was also anglicized Collins, and after the migration the two blended in the same territory. Collins is also a common English surname, from a diminutive of Nicholas, so county and parish records show which of these roots a family grew from.
Collins spelling variants

Michael Collins and the West Cork connection
Michael Collins (1890–1922), the revolutionary leader, chairman of the Provisional Government and commander-in-chief, is the most internationally recognized historical bearer of the name. He was born at Woodfield, Sam’s Cross, in west County Cork. He was born in the very district where the Ó Coileáin family settled after leaving Limerick, and his role in the independence struggle made the name famous far beyond Ireland.
Migration and the Collins diaspora
Collins families left Ireland through many routes, including nineteenth-century emigration to Britain, North America and Australia. Passenger lists and overseas censuses can identify a destination, but the strongest bridge back to Ireland is usually a specific county, parish or townland recorded in a marriage, death notice, military file or naturalization record.
