Ibstone was held by Hervey the legate (possibly an interpreter) from the king in 1086. It was assessed at 2 hides with woodland for 100 pigs. Confusingly a second holding of one hide with 3 acres of meadow in Ibstone was recorded under Hervey’s name in the Oxfordshire returns. In 1270 Henry III granted the manor to Walter Merton, Bishop of Rochester, for the endowment of Merton College Oxford. Subsequently the advowson of the church passed to the college.
