The Norman conquest was “a heavy blow and great discouragement” to the impetuous Britons. During that eventful period almost the whole of Shropshire was parcelled out, and bestowed by William the Conqueror on his kinsman, Roger de Montgomery, as a reward for his great military services in the conquest. The Earl of Shrewsbury, whilst thus taking possession of Powys, among his other newly-acquired lands, brought under his subjection the town and castle of Trefaldwyn, (from Baldwin, Montgomery’s lieutenant,) which fortress he strongly fortified, and afterwards called it after his own family name. Hugh Lupus, Earl of Chester, (the founder of the Grosvenor family,) likewise did homage for Englefield and Rhûvoniog, with the country extending along the sea shore from Chester to the waters of Conway. Ralph Mortimer did the same for the territory of Elvel; as did Hugh de Lacie for the lands of Eulas; and Eustace Cruer for Mold and Hopedale. Brady relates out of Domesday, that William the Conqueror granted to Hugh Lupus North Wales in farm, at the rent of £40 per annum, besides Rhos and Rhûvoniog. These Norman Barons erected fortresses on their lands, and, so far as they were able, settled in them English and Norman defenders. In a MS., relating to the Welsh Marches, from the library of the late Philip Lloyd Fletcher, Esq., of Gwernhaylod, in Flintshire, it is stated “that about this time, Bristol, Gloucester, Worcester, Shrewsbury, and Chester were rebuilt and fortified, and formed a line of military posts upon the frontiers.” Thus the last asylum of the Welsh was invested on almost every side, or broken into by their enemies. The kingdom of North Wales, reduced to the island of Anglesey, to Merioneth and Caernarvonshire, and to part of the present counties of Denbigh and Cardigan, still preserved the national character and importance. The natives of Wales, aided by the virtue and courage of their Princes, became more formidable than ever to the English; and at times, as they acquired union with additional vigour from despair, their invaders, instead of being able to make new conquests, held those which they had already obtained by a precarious tenure. William’s policy, in giving to his barons the power to make such conquests in Wales as they were able, led to the erection of the Marches Lordships, of which Oswestry formed a part. These lordships consisted of more than a hundred petty sovereignties, and were the fruitful source of innumerable disorders, till their partial suppression in the reign of Henry VIII. Pennant says, that William’s design was, in establishing these seignories and jurisdictions, to give to those whom he had brought over to England the power of providing for themselves, and to reduce, at the same time, the opposition of the Welsh people. The precise extent of the Marches Lordships it is difficult, as we have already said, to define. During the Saxon period the Severn was considered the ancient boundary between
