Dogfael, King of Dogfeiling
(Born c.AD 429)
(Latin: Docomaglus; English: Dogbald)

Dogfael was the supposed eighth son of Cunedda Wledig (the Imperator). When the Irish became dominant in North Wales, he is said to have travelled, with his family, from their home in Manau Gododdin (on the Firth of Forth) to expel them. Dogfael was then traditionally given the area around Rhuthin as a reward and there he set up the kingdom named after him. He probably ruled as a sub-king under King Einion Yrth (the Impetuous) of Gwynedd but whether he was really his brother is uncertain.

It is unclear for how long his descendants continued to use the title of 'King', but they appear to have enjoyed a certain amount of power in the area, if not a great deal, probably into the early eighth century. He was succeeded by his son Elno and, later, his grandson, Glas.
