Ceneu

Saint Ceneu, Bishop, was a bishop of Menevia (St Davids) in Wales in the sixth century. Giraldus Cambrensis, writing in the twelfth century, counted him the third bishop of the see. According to tradition he was a son of Corun, son of Ceredig, or of Coel Hen.

He founded a church or monastic community (clas) at the place now called Clydau in north Pembrokeshire, which was long known as Llangeneu, "the church of Ceneu". No traces of the settlement survive; it is thought to have been lost when the Flemings settled in the district.

Ceneu is a saint of the undivided Church, honoured locally. His feast is kept on 15 June (new style, Western calendar).
