In 1276, Henry de Tracy was referred to as le *bozu in an inquisition into the Devon manor of Morton (now Mortonhampstead) which was his father’s principal manor.
‘Morton. The manor, tenure unknown for, William de Tracy who held the barony of Braneys and Morton of the king in chief, took part (fuit in auxilium) in the martyrdom of St. Thomas of Canterbury, for which deed he went into exile and the barony became the escheat of King Henry the king's ancestor. The same William had a son Henry de Tracy, le Bozu, born in Normandy, who long after came to Geoffrey son of Peter, chief justice of England, grandfather of John son of John, praying him to aid him in recovering his inheritance…’ - Inquisition Post Mortem, Saturday after St. Edmund the King, 4 Edw.
