Quinn

Quinn is an Anglicised form of the Irish Ó Coinn or Mac Cuinn. The latter surname means "descendant of Conn". The surname Quinn is also rendered Ó Cuinn or Mac Cuinn in Irish. The surname is borne by several unrelated families in Ireland, especially in Ulster and also in the counties of Clare, Longford, and Mayo. According to the historian C.

The most notable family of the name are that of Thomond, a Dalcassian sept, who derive their surname from Niall Ó Cuinn who was slain at the Battle of Clontarf in 1014. This family was formerly represented by the Earls of Dunraven. Another family is that seated in Annaly, who were related to the O'Farrell lords of Longford. Another Quinn family was seated at An Chraobh, County Tyrone and they were related to the O'Neill Kings of Tír Eoghain and for whom they acted as Hereditary Quartermasters. Other families include one seated in County Antrim; one seated in Raphoe; and one called Clann Cuain, seated near Castlebar. In the seventeenth century, the surname Quinn was common in Waterford. In 1890, the surname was numerous in Dublin and in counties Tyrone, Antrim, and Roscommon. Quinn is one of the twenty most common surnames in Ireland.
