Green's Norton was held by the king in 1086, and by the Confessor before the Conquest. No church was recorded at that time. There is Anglo-Saxon fabric, however, and the issue of a charter towards the end of the 12thc. in which Robert de Leya, nephew of the founder of Canons Ashby priory, agreed to pay a tax to Green's Norton, presumed to be for the lands on which the priory stood suggests that it may have been a substantial minster. In the late 12thc. King Richard I granted this manor and others, to the Earl of the Isle of Wight, Baldwin de Betun to be held by the service of three knight's fees, and a fee farm rent of £4 yearly. From him it passed, with the hundred of Norton to William Earl of Pembroke, wife of his daughter Alice. It then passed to John le Mareschall, his son and remained in this family throughout the 13thc. and into the 14th.
