The Senchus fer n-Alban makes him a son of Eochaid Buide and thus a member of the Cenél nGabráin. The Duan Albanach has him succeed Ferchar mac Connaid of the Cenél Comgaill, which had not yet separated from the Cenél nGabráin. He was co-ruler with Dúnchad mac Conaing until 654, after which he was apparently sole ruler.
