House Mowbray /ˈmoʊbri/ is an Anglo-Norman Baronial house, derived from Montbray in Normandy and founded by Roger de Mowbray, son of Nigel d’Aubigny. From this village came Geoffrey de Montbray who came to be Bishop of Coutances and accompanied Duke William of Normandy at the Conquest of England in 1066. For his support he was granted some 280 English manors (each about the size of a village).
