St. Cynwyl
(Born c.540)
(Welsh: Cynwyl; Latin: Conuvilius; English: Conwald)

Cynwyl was supposedly a warrior saint who fought for King Arthur at the fateful Battle of Camlann. He was a giant of a man and one of only seven to have survived the slaughter. He escaped on his horse named Hengroen. The beast is remembered in the name of the place, Dinhengroen, in Abergele.

Cynwyl reputedly founded churches at Cynwyl Gaeo (Ystrad Tywi), Cynwyl Elfed (Ystrad Tywi), Aberporth (Ceredigion) and Penrhos (Llyn). He died on 8th January, possibly in the late 6th century. He is sometimes said to have been the son of King Dunaut Bwr of the Northern Pennines, although this appears to stem from a misreading, by Iolo Morganwg, of a line in the ancient poem, 'Y Gododdin'.
