The English surname Keynes is derived from a Norman place name, either Cahagnes (Calvados) or Cahaignes (Eure), which are documented as places of origin of people of this name[1] or possibly also from similar placenames not so documented.

The earliest documented person in England bearing the name was William de Cahaignes from Normandy who was born around 1035. Of another Norman William de Cahaignes (born around 1060 and probably his son), Katharine Keats-Rohan writes:- "Norman, from Cahaignes, Calvados, arr. Vire, cant. Aunay-sur-Odon.[2] Major tenant of Robert, Count of Mortain (half-brother of William the Conqueror) in several Domesday counties. He was Sheriff of Northamptonshire in 1086, and again in the early years of Henry I. His widow Adelicia made a grant for his soul to Lewes priory, with the assent of their son Hugh (Mon. Ang. v,14). His lands were divided between his three sons, of whom Hugh held the forest of Northamptonshire in 1129/30." [3]
