GUILLAUME DE CAHAIGNES.
Le sire "de Cahaignes," chronicled by Wace (l. 13664), was Guillaume, whose family came from Cahagnes in the arrondissement of Vire, which was held of the count of Mortain in whose train he, beyond doubt, came to England at the conquest. Guillaume was one of the count's principal feudatories in Normandy as well as England, where he held lands in Buckingham, Sussex, Cambridge and Northampton. He was tenant-in-chief in the latter two counties, his seat having been at Dodford in Northamptonshire. His son Ralph occurs in Domesday as Radulfus de Caisned, holding Horsted-Keynes in Sussex; he was a benefactor to Lewes priory, as was his grandson Ralph, between 1091 and 1097. The latter Ralph married a Kentish heiress and was granted by Henry I, Tarent and Combe in Dorsetshire and also Somerford in Somersetshire, while Tarent-Keynes was his seat. The lords of Cahagnes were among the benefactors of the abbey of Grestin in Normandy, and were prominent in that country during the 12th century and in England for many years
