"The lands in Normandy were (eventually) inherited by Henry de Ferrieres, … (s. and h. of one of his [Henry de Ferrieres'] brothers, Engenulf or William). Henry, who was living in 1136, held Oakham, co. Rutland, and Lechlade, co. Gloucester (a manor held by his grandfather Henry at the Domesday Survey). He was father of Walkelin, who was father of (i) Henry, Seigneur de Chambrais in 1202, (2) Hugh, of Lechlade, who d. s.p. in 1204, having m. Margaret, da. and h. of Hugh de Say of Richard's Castle, and (3) Isabel (d. before 31 May 1252), who m., 1stly, Roger de Mortemer of Wigmore (d. 24 June 12 14), and 2ndly, Piers fitz Herbert of Blaen Llyfni (d. 1 June 1235). Isabel inherited Lechlade, and also Oakham, which her eldest br., Henry, had lost at the time of the conquest of Normandy. Henry was the ancestor of the seigneurs of Ferrieres and Chambrais, the last of whom, Jean, d. s.p.m. in 1504. A custom quite recently existed that a peer of the realm, the first time he passed through Oakham, should give a horse-shoe to be nailed upon the castle-gate: a toll or privilege dating, no doubt, from the time of the ancient lords of that town, premiers barons fossiers of Normandy."
