From Ó Cuinn, descendants of Conn — several distinct Gaelic septs, most notably in Tyrone and Clare.
Gaelic Origin · Root name Conn, ‘chief’ or ‘wisdom’
Quinn descends from Conn, a personal name associated with leadership and, in legend, with Conn of the Hundred Battles. Several unrelated Ó Cuinn septs took the name independently — most prominently in Tyrone, but also in Clare and Longford.
A name claimed by more than one Gaelic family, in more than one corner of Ireland, each convinced — rightly — that it belonged to them too.
Irish form: Ó Cuinn
