The Barony of Huntingfield was has been created thrice: twice in the Peerage of England and then in the Peerage of Ireland. The first two creations were by writ, but little more is known about them. They probably became extinct or fell into abeyance at the death of their first holders. The Irish barony, created in 1796 by letters patent, is still extant.
Dover Castle, the stronghold which William de Huntingfield held in the Barons' War, is a famous one, fulfilling the dream of the grim place of nameless cruelties and horrible prisons.
Very likely the cause of the Protector's severity toward Huntingfield was that he was one of those who plotted to have the Dauphin come to England and, after the Dauphin's landing, was very active in reducing the Courts of Essex and Suffolk to French authority.
William had a daughter, Alice Huntingfield, who was married twice, but the name of her first husband has not been preserved.
