some difficulty with the Columban church as well when Mael Dúin son of Cenn Faelad, superior of Ráith Both (Raphoe) was killed in 817. The Columban church went to Tara to excommunicate Áed that year. This event probably had something to do with his campaign versus the Cenél Conaill in 815. Also in 818 Cuanu, abbot of Lugmad Louth, went into exile into the lands of Munster with the shrine of Saint Mochtae, fleeing before Áed. Family Áed had married Euginis ingen Donnchada (died 802), daughter of Donnchad Midi. His son Niall Caille (died 846) was later king of Ailech and High king of Ireland. Another son Máel Dúin mac Áeda was also a King of Ailech.
