Shrines to Breton saints are found in many regions of northern Europe.

St Albinus (St Aubin) of Vannes, Bishop of Angers, is honoured all across northern France and as far away as Poland.

St Samson is honoured in Conteville, of which Count Robert of Mortain’s and Bishop Odo’s father Herluin was made Viscount.

“Viscount Robert and his brother Odo” occur as witnesses to a charter issued by Count Eudon, Duke of Brittany, at Rennes prior to 1050.

“Alan Rufus, son of Count Eudon” witnessed a charter by Yves de Bellême, Bishop of Séez, dated between 1047 and 1067.

Alan Rufus was captain of William’s palace guard in Normandy, and often appears near Bishop Odo on the Bayeux Tapestry, though they probably became unfriends over various actions of Odo’s later.
