Guy de Craon held 8 carucates of land in Stonesby in 1086, and the same family held the manor. Alan de Craon, Steward to Henry I, (1100-35) founded a priory of Benedictine monks at Freiston, Lincolnshire, annexing it as a cell to Croyland Abbey to which he gave, amongst other things, the church at Stonesby.
