Domnallan mac Maelbrigdi

The bardic family of Ó Domhnalláin derived their surname from him. Originally located in Ballydonnellan, County Galway, they were of a sept of the Uí Maine called Clann Breasail, who held the position of Cathmhaol or Battle Champion.

Descendants of the Uí Domhnalláin are still found in Galway and Roscommon under the surname Donnellan.
