William de Mauduit or Malduith was living 1086, the year the survey was recorded in the Domesday Book, and at that time possessed seven lordships in Southampton. He also is styled by Dugdale in his "Baronage" as Chamberlain to Henry I. The two baronial houses of Mauduit were Mauduit of Hanslape, County Bucks, hereditary Chamberlains of the Exchequer; and Mauduit of Warminster, County Wilts, and of Castle Holgate, County Salop, sometimes Chamberlains Royal. These were closely related by intermarriages.
