A legend related to the Conaille Muirtheimne states that Conall Constamail mac Finnchada fathered three sons, Rúntar, Glass and Ímda (eponyms of the Dál Rúntar, Glasraige and Dál nÍmda) upon his own daughter Creidne; out of shame he banished her and her sons; she fought against her parents and only after seven years of exile did she reach a settlement.
