6th Earl of Chester. He is styled "of Kevelioc," also viscount d'Avranches. When his father died in 1153, Hugh, still underage, succeeded to the family possessions on both sides of the channnel. These included the hereditary viscounties of Avranches and Bayeux. Hugh was present at the council of Clerendon in 1164 which drew up the assizes of Clerendon. He joined the rebellion against Henry II begun by Henry's son, Henry, the Young King, in 1173. He was influential in inciting Brittany to revolt. He was taken prisoner at Alnwick, July 13, 1174, after a long siege, and deprived of his earldom. Hugh was shuffled from prison to prison until the general peace commencing with the peace of Falaise in 1174, to which Hugh was a witness. He was again in rebellion, but was restored to his earldom and lands in January, 1177. Henry II required Hugh to participate in the Irish campaigns, but Hugh took no prominent part and received no Irish estates. Hugh's son, Ranulph, succeeded to Hugh's estates and to the earldom of Chester upon Hugh's death in 1181, but Ranulph died without an heir, so Hugh's four daughters became coheiresses.
