Life

Holy Hierarch Sadyrnfyw, also called Sadwrnfen the Generous (in Welsh Sadyrnfyw Hael, in Welsh Latin Suturnius), was bishop of Meneva (today St David's) in medieval Wales and reposed around 831. His death is mentioned in the undated sections of the Annals of Wales. Phillimore's reconstruction of the dating places the entry in the year 831, and the Chronicle of the Princes in 830.

No other details survive in the sources at hand. He is honored as a saint of the undivided Church, in the Welsh tradition.
