Shrewsbury, Earldom of: His [Roger, 1st Earl of Shrewsbury's] son, the 2nd Earl of Shrewsbury (or Shropshire) of the 1074 creation, was killed by a missile launched from a Norse (or conceivably Irish) raiding party off the Anglesey coast while riding along the forshore on that island trying to fend them off. He was accounted gentle by the English and Normans but a Hammer by the Welsh. Under the systerm then prevailing the Earldom passed to an elder brother, Robert de Belleme, who constructed Bridgnorth Castle and continued the family policy of harrying the Welsh. He rebelled against Henry I and in 1102 was deprived of the Earldom of Shrewsbury/Shropshire, together with his English and Welsh estates. [Burke's Peerage, p. 2604]

EARLDOM OF ARUNDEL (II)
EARLDOM OF SHREWSBURY (II)
HUGH (DE MONTGOMERY), EARL OF SHREWSBURY, 3rd but 2nd surviving son by 1st wife, was born probably between 1053 and 1059 (b). In December 1079 he was at the Castle of Bures when his mother was murdered there and he pursued the murderers in vain. In the summer of 1080 at Caen he joined his brothers in attesting his father's charter for Troarn for the soul of their mother. Before his father's death he was already recognised as his heir in England. In 1092 he was at the siege of Breval and with other magnates he made peace between William de BrÈteuil and Ascelin Goel. On Roger's death in 1094 he succeeded him as EARL OF SHROPSHIRE or SHREWSBURY and to all his lands in England and Wales. In that year the Welsh rose in arms. Hugh fought them with some success in North Wales, but in 1095 they took Montgomery and slaughtered the garrison. Hugh took part in the conspiracy against William II in 1095, but he bought the King's favour for £3,000. In 1098 with the Earl of Chester he invaded and conquered Anglesey, treating the Welsh with great cruelty. When a Norwegian fleet appeared off the coast of North Wales, the 2 Earls met at Diganwy (co. Carnarvon) and crossed to Anglesey. As the fleet approached the land, the Earl rode along the shore and was struck by an arrow shot, or a javelin thrown, from a ship and fell dying into the sea. Thus he died unmarried about 31 July 1098 and was buried about 17 August at Shrewsbury Abbey.[d] [Complete Peerage XI:688-9, (transcribed by Dave Utzinger)]
(b) He may or may not have been the 3rd child. According to a Welsh annalist, he was fighting in Wales in 1072; but this seems impossibly early. Note: I think that many of Roger II's children were born earlier than CP states.
[d] The Normans and English long sought for his corpse, drawn away by the tide, and found it at length; and on the 17th day after his death bore it to Shrewsbury, where it was buried in the abbey amid great mourning. He was the only one of the sons of Mabel who was gentle and amiable. This seems hardly compatible with the alleged cruelties to the Welsh in Anglesey.
Note: Hugh died unmarried, but I have a son, undoubtedly illegitimate, by him.
