Baring-Gould’s sources: Audently commemorated in Wales. Alban Butler on Nov. 23.] Deiniol Wyn, the son of Dunawd Fyr by Dwywe, a daughter of Gwallog ab Llenog, assisted his father in the establishment of the monastery of Bangor Iscoed, in Flintshire. He is said also to have founded another monastery, called Bangor Deiniol, in Carnarvonshire. Soon after this latter was raised by Maelgwn Gwynedd to the rank of a bishop’s see, and Deiniol became its first bishop. It is said that he received consecration from S. Dubricius, an event which must have occurred, if true, before 522. But it is much more probable that he was consecrated by S. David. His father, called Denooth by Bede, was abbot of Bangor Iscoed at the time of the council of the Oak with Augustine (a.d. 600-3). The poems of Llywarch H6n, a contemporary, prove that Dunawd was engaged in battle with the sons of, Urien Rheged, who was living in 560. Dunawd was therefore not abbot till the end of the sixth century, and his son Deiniol was not bishop till the beginning of the seventh century. He is said to have been present at the synod of Llanddewi-Brefi, which is thought to have taken place before 569; but this synod rests on the authority of Rhyddmarch, and is very doubtful. Deiniol certainly was not bishop at that time. Geoffrey of Monmouth says that Deiniol died at the same time as S. David. He died no doubt about half a century later than S. David.
