 John de Vieuxpont died in 1241 , before he came of age . The new heir , John 's son Robert , was not old enough to inherit , so the family 's lands remained in wardship . During this time , the estates to fell into disrepair , and this probably included Brougham Castle . When Robert de Vieuxpont came of age in around 1257 he inherited considerable debts . He was one of the northern lords that revolted in support of Simon de Montfort in the Second Barons ' War ( 1264 – 1267 ) . By June 1264 , Vieuxpont was dead ; as he was considered a traitor , his property was confiscated by King Henry III . In 1266 , the king pardoned Vieuxpont posthumously , and his two daughters inherited the family estates . The guardians of the two girls , who at the time were too young to marry , divided the Vieuxpont lands with the expectation that they would come into their possession through marriage . Isabel Vieuxpont was given in marriage to Roger Clifford , the son of her guardian , and with her the shrievalty of Westmorland and the castles of Brougham and Appleby transferred to the Cliffords .
