 Both William VI and his son William VII died young, ending the family line in 1261.An enquiry was held to resolve the question of whom should inherit the de Eynsford lands; Eynsford Castle and the other family estates were divided equally between William Heringaud, a powerful landowner in east Kent, and Nicholas de Criol, a smaller local Kentish landowner, both of whom were descended from William V. The Second Barons' War broke out in 1264 and both men supported the rebels against Henry III.Eynsford, by now unoccupied, was seized by Ralph de Farningham, a royal official, who in turn passed it onto Ralph de Sandwich, a royal judge.
