a descendant of Maelgwyn, was the son of Iago ap Beli, reported in the Annales Cambriae to have died 613. Geoffrey of Monmouth offered an elaborate account that Cadfan was chosen to lead the Welsh when they were attacked by Aethelfrith of Bernicia, and that he gave shelter to Edwin, who gained the Northumbrian throne from Aethelfrith in 616. Cadfan died in 625. His gravestone is at Llangadwaladr on Anglesey.
