Einion Yrth, King of Gwynedd
Einion Yrth (the Impetuous) originated in Manau Gododdin on the Firth of Forth. He travelled to North Wales with his father, Cunedda Wledig, in the early 5th century to expel the invading Irish. Despite, apparently, being the seventh son, he must have been of strong character for he became heir to his father's central power-base of Gwynedd. The kingdom was named after the Irish people known, in Latin, as the VenodotŠ. From here, Einion was eventually able to impose himself as over-king to most of his brothers.
