Until the Norman conquest of England the manor of Beckley was one of many that belonged to Saxon Wigod, thegn of Wallingford. After the conquest the Norman baron Robert D'Oyly married Wigod's daughter Ealdgyth and thereby acquired Wigod's estates. D'Oyly then gave a number of the manors to his brother-in-arms Roger d'Ivry. These included Beckley, which d'Ivry then made the "caput" of his estates. Beckley remained with Roger's heirs until early in the 12th century, but the d'Ivry family seems to have died out by about 1120.
