House of Óengus

The House of Óengus is a proposed dynasty that may have ruled as Kings of the Picts, as well as overlords of the Kings of Dál Riata and possibly of all of northern Great Britain, for approximately a century from the 730s to the 830s AD. Their first ruler of Pictland was the great Óengus I of the Picts, who may be the figure carved into the St Andrews Sarcophagus pictured on the right.

Early (but not contemporary) Irish genealogies make Óengus a member of the Eóganachta of Munster, as a descendant of Coirpre Cruithnechán or "Cairbre the little Pict", a legendary emanation or double of Coirpre Luachra mac Cuirc, son of Conall Corc, and ancestor of the Eóganacht Locha Léin, rulers of the kingdom of Iarmuman. An early cycle of tales have Conall Corc traveling to Pictland early in his career, and there taking the daughter of the Pictish king as his first wife, hence Coirpre's epithet. The branch of the kindred, called in the annals the Eoghanachta Magh Geirginn, from which he came were said to be located in an area known as Circinn, usually associated with modern Angus and the Mearns. The genealogy appears in the Rawlinson B 502 manuscript, ¶1083:

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:

This states that from Coirpre Cruithnechán come a sept of the Eóganachta in Alba called the Eóganacht Maige Gerginn, to whom belongs Óengus I.

Notably lacking are over two centuries of generations in Scotland. Conall Corc is said to have flourished in the early 5th century. Óengus I belongs to the 8th.
