Sorry, this is all I could find: We know there was a Saxon settlement at Hamsey in AD925 and it is recorded in the Domesday Book of 1086. A manorial hall was built in 1321 to the east of Hamsey Church. Lords of the manor have included the families of de Cheyney, de Say, de Clinton, Willoughby, Dudley, Lewknor, Alford, Wenham, Partington and Monk Bretton. Lords of the manor of Coombe, (Offham), include the families of de Say, Radmelde, Comber, Pelland, Scrase, River, Bridger and Shiffner. Not a clue to the meaning of the name but one can imagine a local saying such as "God's grace" being abbreviated to "'s Grace." So we almost agree this time, eh Gordon? Gary Radcliffe
