The early English kings had parted with their manor of Kingsbury long before the Conquest. An estate called Tunworth, in the northern part of Kingsbury parish, was granted by Edwy to his thegn Lyfing in 957. By 1066 it probably formed part of the manor of Kingsbury, which was then held by Wlward White, a thegn of the Confessor, and passed from him to Ernulf of Hesdin who died in 1097 and his lands passed to the family of Walter of Salisbury. Thereafter the overlordship of Kingsbury descended with Edgware manor. By 1086 on the Domesday survey of property, Ernulf's manor in Kingsbury had been subinfeudated to Albold as Lord. It was not mentioned again until 1317, when, under the name of the manor of Kingsbury, it belonged to Baldwin Poleyn of Tebworth.
