Deiniolen the Son entered the Church after having been raised from the dead by St. Beuno after he had accidentally drowned. He founded monasteries at Llandanielfab on Ynys Mon (Anglesey) and Llandeiniolen near Bangor Fawr. Since the 18th century, he has been identified as the son of Prince Deiniol Gwyn (the Blessed) of the Northern Pennines, who was also the founding Bishop of Bangor Fawr, where Deiniolen succeeded him.
