 The Duan says that Domnall reigned for twenty-four years and places him between "Aodh", Áed Find, and the two Conalls, Conall mac Taidg and Conall mac Áedáin.Flann gives Domnall's father's name as "Constantine".The only person of that relatively uncommon name known is Causantín mac Fergusa, king of the Picts from 792 to 820.
