(fl.550?) British saint, commemorated on 4 June, was the founder of the ancient church of Bodmin, where his relics were long preserved. The life in Acta Sanctorum is meagre and of no authority. We only learn from it that Pedrog was natione Cumber (i.e., a Welshman), and of royal birth. On the death of his father he declined the succession to the crown, and, with sixty companions, retired to a monastery. After studying in Ireland for twenty years, he spent another thirty in monastic seclusion in Britain. Then he visited Rome, Jerusalem, and India, living for seven years on a desert island in the Indian Ocean. He returned to Western Britain, and ultimately died there on 4 June. The Life of Saint Cadoc in , which was apparently written about 1070, so far confirms this account as to make Pedrog a son of King Glywys of of what is now Glamorgan, who did not take his share of the royal inheritance with his brothers, but served God at “Botmenei” in Cornwall, where a great monastery was afterwards founded in his honour. Other manuscripts call Pedrog the son of “Clemens tywysog o Gernyw” (i.e., a prince from Cornwall).
Pedrog is called by Fuller, “the captain of the Cornish saints,” and the number of dedications to him in Devonshire and Cornwall show that his name was widely revered in the district. He is the patron saint of Bodmin, Padstow, Trevalga and Little Petherick in Cornwall, and of West Anstey, South Brent, Clannaborough, Saint Petrock’s, Exeter, Hollacombe, Lidford and Newton Saint Petrock in Devonshire. Llanbedrog, Carnarvonshire and Saint Petrox, Pembrokeshire, are also dedicated to him. He was, moreover, honoured as Saint Perreux in the monastery of Saint Meen in Brittany, and in 1177 the monks of Saint Meen made an unsuccessful attempt to obtain possession of his relics.
