‘Silver-tongued’ William Murray (1705-93), the 1st duke of Newcastle’s political henchman, became lord chief justice in 1756 and was created Lord Mansfield. His marriage was childless and in 1776 he was promoted to the rank of earl with a special remainder (on the mistaken assumption that a Scottish peer could not take an English peerage other than by inheritance) to Louisa Cathcart (1758-1843), the wife of his nephew David Murray, 7th Viscount Stormont (1727-96), a Scottish representative peer who was lord president of the council in the Coalition and under Pitt from 1794 to his death. In 1792, after a ruling which removed this misapprehension, Mansfield received a new patent as earl of Mansfield, Middlesex, with remainder to Stormont, who duly succeeded to this peerage the following year, when his wife became countess of Mansfield under the 1776 creation.
After leaving Oxford Stormont, Mansfield’s eldest son, toured Europe, and he attended the coronation of Nicholas I in Moscow in the summer of 1826. Three years later he consummated ‘an old and long attachment’ by marrying ‘that enticing looking female Miss Ellison’.
Newcastle settled that Stormont should ‘change places’ with Sadler, whose re-election for Newark was extremely doubtful; but at the last minute Stormont pulled out of the arrangement, to the intense annoyance of the duke, who blamed Mansfield’s ‘most selfish’ intervention. Aldborough went to Sadler and Stormont found a berth at Woodstock, where he came in on the Blenheim interest after a token contest.
Stormont voted against the revised reform bill in the divisions on its second reading, 17 Dec. 1831, going into committee, 20 Jan., and the enfranchisement of Tower Hamlets, 28 Feb. 1832. He voted for the Vestry Act amendment bill, 23 Jan., and against government on the Russian-Dutch loan, 26 Jan. He objected to the admission of a petition from the Political Union against making the payment of rates a qualification for the vote, 2, 6 Feb. He defended a Barnet petition condemning the reform bill against allegations of chicanery in its promotion, 10 Feb. Soon afterwards John Croker* noted that Stormont was one of the Ultras who were now ‘very cordial’ in their attitude towards Wellington and Peel, though he seemed by implication to set little store by his parliamentary talents.
Stormont remained on reasonably cordial terms with Peel, who strongly urged him to take junior office in his first ministry in December 1834. Mansfield made some difficulties, but Peel sweetened him with a vacant green ribbon, and Stormont took a seat at the treasury board.
