He was the son of Pasgen ab Urien Rheged, of the family of Coel Godhebog,[1] and father of Saint Nidan.
[2] A single manuscript holds that he had brothers Mydan and Llamined who the Venedotian Tribes of Collwyn ab Tangno and Marchweithian traced their descent through him.
[3] He is said to have a church dedicated to him in Anglesey, but its situation does not appear to be now known.
There was formerly a Capel Gorfyw at Bangor,[4] but it has long since disappeared.
The only written evidence of him is as a witness to a land grant in Monmouthshire.
