His father Richard seems to have died between 1115 and 1138, in which latter year we find 'Walter de Cliffort' signing a Gloucester charter.
He probably obtained the barony of Clifford from his wife Margaret, asserted to be the daughter of Raoul IV de Conches and thus the granddaughter of Raoul II of Tosny, feudal lord of Flamstead, who is shown, in 1086, as 'tenant-in-chief' of this fee, the multiple lords being listed as Drogo (son of Poyntz); Gilbert (son of Turold); Herbert; and Roger.
(A second listing for Clifford in Domesday shows Roger de Lacy, as lord and tenant-in-chief, of a small portion of this barony, being taxed on 4 carucates.)
He ravaged the lands of Rhys ap Gruffydd, who, finding his complaints to Henry II disregarded, surprised his castle (1157-9).
[3] He married Margaret de Toeni, daughter of Ralph de Toeni, having children by her: The main part of the Clifford estates passed to Matilda, a great-granddaughter, wife of Sir William Longespée (grandson of William Longespée, 3rd Earl of Salisbury), whose daughter, Margery Longespée, brought them to her husband, Henry de Lacy, 3rd Earl of Lincoln.
