High Quality Content by WIKIPEDIA articles! Earl of Wilton, of Wilton Castle in the County of Hereford, is a title in the Peerage of the United Kingdom. It was created in 1801 for Thomas Egerton, 1st Baron Grey de Wilton, along with the subsidiary title of Viscount Grey de Wilton, also in the Peerage of the United Kingdom. Both titles were created with remainder to the second and all younger sons successively of his daughter Lady Eleanor, wife of Robert Grosvenor, 1st Marquess of Westminster. Egerton had already succeeded as seventh Baronet of Egerton and Oulton in 1756 and been created Baron Grey de Wilton, of Wilton Castle in the County Hereford, in the Peerage of Great Britain, in 1784, with remainder to the heirs male of his body. Lord Wilton, who had earlier resided at Heaton Hall near Manchester and represented Lancashire in Parliament, was a descendant of Sir Roland Egerton, 1st Baronet, who married Bridget, sister and co-heir of Thomas Grey, 15th Baron Grey de Wilton, who was attainted in 1603 and forfeited his title. On the Earl's death in 1814 the barony of Grey de Wilton became extinct as he had no male heirs, while the baronetcy was passed on to his kinsman, the eighth Baronet (see Grey Egerton Baronets for additional information on this title).
