In 1086 Odo, Bishop of Bayeux held 1 carucate of land in South Carlton, previously held by Ealdormann. The land is held from the bishop by Ralph the Steward and Earnwine the priest, and there is a church too. Earnwine said that it ought to belong to the king.

A further 6 carucates were held by Gunnhvati before the Conquest and by Svartbrandr in 1086.

According to a note posted in the church, this human-faced basin was set into the wall to the S of the altar, confirming its use as a piscina. It remained in that location until 1861 when the rebuilding of the S aisle may have required the movement of the piscina from its original location.
