House of Óengus

The House of Óengus is a proposed dynasty that may have ruled as Kings of the Picts and possibly of all of northern Great Britain, for approximately a century from the 730s to the 830s AD.

The branch of the kindred, called in the annals the Eoghanachta Magh Geirginn, from which he came was said to be located in an area known as Circinn, usually associated with modern Angus and the Mearns.

filios habuit id est: Cairpre Cruithnechán nó Carpre Luachra mc Mongfhinne ingine Feradaich Find Fechtnaich ríg Cruthentuaithi ideo, Cairpre Cruithnechán nuncupatur & a quo Éoganacht Locha Léin.This states the king of Pictland with whom Conall Corc stayed to have been Feradach Find Fechtnach, and his daughter, Conall's first wife and Coirpre's mother, to have been Mongfind.

After discussing Corc's progeny in Munster, the future Eóganachta of history, the passage concludes with: ...Cairpre Cruithnecháin a quo Éoganacht Maigi Dergind i n-Albae .i.

Francis John Byrne puts this in the context of the (wider) Gaelicisation of Pictland in the 9th century, and notes how later Scottish dynasties such as the Lennoxes and the House of Stuart also found Corc to be a "usefully respectable" Gaelic ancestor.
