From Chicklade And Pertwood, A Short Parish History by E.R. Barty, M.A., Chicklade, Old Rectory, first published December 1955:
The Great Ridge appears as:
Chickladriggh 1348 A.D.
Chickladerigge 1367.
Chicklade Ridge Woods or Chicklade Ridge Coppices 1635.
Chicklade Ridge or Great Ridge 1773.
An early reference to the Ridge Wood is in “Lacock Abbey†(Bowles). The Abbey had a Close in the Wood of Chicklade in connection with their estate at Chitterne. In 1267 it was agreed by certain persons that the Nuns should hold for ever their Close at Chicklade, whether old or new. The title was quitclaimed to them by Joan, daughter of William Archer.
