The early history of the family will be found in The Complete Peerage, surname Mowbray, new ed., vol. ix, pp. 366-7. The details of their benefactions to the abbey of Lessay as confirmed by a charter of Henry II, 1185-1188, identify St-Martin d'Aubigny with the Aubigny which was the caput of their Norman honour; thus the "ecclesiam de Folgeriis" is Feugeres 2 1/2 kil. SE of Aubigny, the "feria Sancti Christofori" mentioned in conjunction with the "forum Albinneii" is St-Christophe-d'Aubigny, a parish now united to that of St-Martin, and "Marchesis" is Marchesieux, 5 kil. NE of Aubigny. There is no trace of a feudal castle at Aubigny itself, but Gerville found nearby at Le Mesnil-Vigot the remains of a considerable castle with a well-defined motte, then known as "le chateau de St-Clair".
