The Parochial History of Cornwall…
“ Lysons’s Cornwall is the best account that the Editor can give of the distinguished family of Grenville.The manor of Kilkhampton is supposed to have belonged to the Grenville family from nearly the time of the Conquest; 344 Dugdale says, that they were seated here in the reign of William Rufus. Richard de Grenville, who came over with William the Conqueror, is said in the pedigrees of the family to have been a younger brother of Robert Fitzhamon, Earl of Carbill, Lord of Thurigny and Grenville, in France and Normandy, and to have been lineally descended from Rollo, Duke of Normandy. ”
