Before 1040 Walchelin de Ferrières "was slain in the civil wars which distracted Normandy during the minority of Duke William." [1] [2]
"Ferrières and Chambrais (now Broglie), on the Charantonne," is "in the chief iron-producing district of Normandy. The workers of iron, in this province, were under the jurisdiction of six barons fossiers; these were the barons of Ferrières, La Ferté Fresnel, and Chaumont, and the abbots of Lyre, St. Wandrille, and St. Evroul. The barons of Ferrières were styled premiers barons fossiers, which shows that the forges they had charge of were esteemed the principal, or the most ancient." [3]
Walcheline, a Norman, had son Henry. [4]
