Clan Sweeney is an Irish clan of Scottish origin. The clan did not permanently settle in Ireland before the beginning of the fourteenth century, when they became Gallowglass soldiers for the O'Donnell dynasty of Tyrconnell. The clan claims an Irish ancestry, from Ánrothán, son of Áed, son of Flaithbertach Ó Néill, king of Cenél nEógain who died in 1036. Through this descent the clan can also claim a descent from Niall Noigíallach (Niall of the Nine Hostages).
