St Brannock lived in the sixth century, and tutored the children of the Welsh ruler Brychan. He went with King Brychan on a pilgrimage to venerate the tombs of the Apostles. On the way home, he stopped in Brittany and remained there several years.
Eventually, the saint returned to Wales and settled at Braunton, where he built a church. His holy relics are said to rest beneath the altar of the Braunton church.
