He is named in Dál Riata king-lists, the Duan Albanach and the Synchronisms of Flann Mainistrech. In some sources he is called Eochaid Crook-Nose (Riannamail), but modern readings take this as being a garbled reference to Fiannamail ua Dúnchado rather than an epithet. The killing of Eochu nepos Domnaill, Eochaid grandson of Domnall Brecc, is reported in the Annals of Ulster for 697.
