The de Cantilupe family which came to England at some time after the Norman Conquest of 1066 originated at one of three similarly named manors in Normandy, from which they took their name: Canteloup in Calvados, east of Caen; Canteloup in Manche east of Cherbourg on the eastern tip of the Cherbourg Penninsula (Cotentin); or Chanteloup in Bréhal, Manche, on the south-west side of the Cherbourg Penninsula, favoured by most sources as an ancient castle survives there.
