A view of Bertram de Verdun's entry in Domesday Book
Bertram de Verdun was the name of several members of the Norman family of de Verdun, native to the Avranchin.
According to the historian Mark Hagger, the de Verdun family lived originally in Normandy where they held land, and after the Norman conquest of England they were granted land in England.[1] Members of the family appear in original records in Normandy from at least c.1068-1085 when the first Bertram de Verdun attests a charter of Guillaume fitz-Guimond of Avranches, who makes a donation to the Abbey of Mont-Saint-Michel.[2]

^Bibliotheque Municipale d'Avranches, Cartulaire du Mont-Saint-Michel (MS 210), folios 83v and 84. Mark S. Hagger, in his 'The Fortunes of a Norman Family: the de Verduns in England, Ireland & Wales' (Four Courts Press, 2001), page 21 & note, gives the date of this charter as 1066, citing Dr Katharine S. B. Keats-Rohan, who provided a transcript to him before publication of her 'The Cartulary of the Abbey of Mont-Saint-Michel' (Published 2009). Despite this, the names of others mentioned in the charter and the dates of their appointments to the offices cited (the Bishop of Avranches and Abbot of Mont-Saint-Michel) indicate that the charter must be dated sometime from 1068 to 1085.
