Humphrey (d. 1182) was sometimes called Earl of Hereford after the failure of the male line in his mother's family, but was never formally installed as earl. He married Margaret of Scotland. Margaret was daughter of Henry of Scotland, 3rd Earl of Huntingdon and Ada de Warenne, a daughter of William de Warenne, 2nd Earl of Surrey and Elizabeth de Vermandois. Since he died before his father, the family lands were inherited by his son Henry de Bohun, 1st Earl of Hereford. Henry was succeeded by his son.
