Oswald Barron, 1911 Encyclopædia Britannica, Volume 18… (1911)
“ Hugh de Mortimer, who is found as his successor, a great Herefordshire baron in 1140, may have been either the son of Ralph’s old age, or a grandson, the son of another Ralph. During the reign of Stephen, Hugh occupied himself with local feuds, but seized the royal castle of Bridgnorth. So great was his power in the marches, that he alone, deserted by the earl of Hereford, armed and held his three castles against Henry II. Although forced at last to submit, he was allowed to keep Wigmore and the ruins of Cleobury. ”
