The Domesday Survey records 2 manors in Norton Mandeville. A manor of half a hide was held by a woman called Godgyth in 1066, and she gave it to the canons of St Paul's Cathedral when King William came to England. A manor of 1½ hides and 15 acres was held by Gotild in 1066 and by Wimund from Hamo the Steward in 1086. This second manor is the one that concerns us. The overlordship passed from Hamo the Steward to his son, also Hamo the Steward, before 1100. He had died by 1130 and the manor passed to his brother, Robert FitzHamon, whose daughter and heir married Robert, Earl of Gloucester. It passed with the earldom to the Clares, and Gilbert de Clare was lord in 1311, and died in 1314, the manor eveantually passing to the crown. More important is the tenancy, which had passed to the Dammartins by the end of the 12thc. Bartholomew de Dammartin (d.before 1190) was succeeded by his brother William (d.1195), whose heir was his daughter Galiena. Her wardship was entrusted by the king to William Brewer, who married her to his brother John. After John's death in 1210 she married Robert de Burgate, by whom she had two children, Peter and Anastasia. Robert de Burgate died after 1120, and by 1128 Galiena was married to Ernald de Mandeville, by whom she had two more children John and Hugh. After a complicated series of exchanges involving John de Madevilee, Galiena and the canons of St Paul's, what remained on the manor was granted to Galiena's daughter from her second marriage, Anastasia. This was in the middle of the 13thc, and for further information after this period the reader is referred to VCH.
In 1181 Norton was included in the parish of High Onger. By 1190 at the latest it had its own church, which was granted by Bartholomew de Dammartin and his mother (another Galiena) to the Priory of St Leonard, Stratford-atte-Bow. The rectory was appropriated by the nuns of Stratford, who retained it until the Dissolution.
