From Chicklade And Pertwood, A Short Parish History by E.R. Barty, M.A., Chicklade, Old Rectory, first published December 1955:
The manor is mentioned in Domesday:-
“The same Bishop (i.e. of Coutances) holds Pertewarde and Asgert of him. Alward held it in the time of King Edward and it paid geld for two hides. The land is two corucates. If this land there is in demesne one hide and a half and there is one corucate. There are two villans (villagers) and three borders (borderers) with one corucate. There are 20 acres of pasture and 4 acres of wood. It was, and is, worth 40 shillings.â€
The Bishop of Coutances in Normandy appears to have possessed several manors which before the Conquest had belonged to the Abbey of Glastonbury.
Colt Hoare writes (c.1829) ‘The whole parish consists of one farm of 448 acres; about 218 acres are arable, 200 pasture and 30 wood. The tythes are held by the proprietor of the estate.’
