Dyfnan

Saint Dyfnan (Dyfnan ap Brychan) was an obscure Welsh saint of the fifth century, born in Wales. He is sometimes accounted a son of Brychan, the Irish king who ruled Brycheiniog. He founded a church in Anglesey. The church of Llanddyfnan in Anglesey was dedicated to him and claimed his relics. He is a saint of the undivided Church, commemorated on 24 April (new style; 7 May in the old style).
