Saint Dwywe

Saint Dwywe was a 5th-century saint of Wales.
Saint Dwywe was a 6th Century native of the ancient Cumbric-speaking kingdoms, which stretched from south western Scotland down as far as South Yorkshire. She is remembered in a church of St Dwywe, Llanddwywe. She was a princess, the daughter of Gwallog ap Llaennog of the royal house based in the Kingdom of Elmet, east and south of Leeds. Her father and the family were forced to flee after a war against the Angles of Bernicia (who were based around Northumberland and Durham). They were taken in by Welsh kinsfolk and settled near Barmouth.
She may have been the wife of Dunawd Fyr and mother of a son, Saint Deiniol, who founded monasteries on Dee-side and at Bangor.
