What the historical record says

Quinn is the anglicised form of the Irish Ó Cuinn, also found as Mac Cuinn, meaning "descendant of Conn," a personal name associated with the sense of chief or leader. The name arose among several unrelated families. The best-known is the Dalcassian sept of Thomond in County Clare, said to descend from Niall Ó Cuinn, slain at the Battle of Clontarf in 1014. Other distinct Quinn families held lands in County Tyrone, where they were connected to the O'Neills, in the Glens of Antrim, and in Annaly, County Longford.

Recorded Gaelic root: Ó Cuinn (also Mac Cuinn)

What this evidence can—and cannot—prove

Census clustering can show where a surname appeared strongly at a historical point in time. It cannot identify your exact ancestor, prove a clan relationship, or assign a coat of arms. Use it as a source-backed starting point alongside family records and parish research.
