Hervey le Breton, bishop of Bangor and Ely

Hervey le Breton was a Breton cleric who became Bishop of Bangor in Wales and later Bishop of Ely in England. Appointed to Bangor by King William II of England, when the Normans were advancing into Wales, Hervey was unable to remain in his diocese when the Welsh began to drive the Normans back from their recent conquests. Hervey's behaviour towards the Welsh seems to have contributed to his expulsion from his see. Although the new king, Henry I wished to translate Hervey to the see of Lisieux in Normandy, it was unsuccessful.
