Kenyon’s grandfather Lloyd Kenyon† (1732-1802), whose mother brought the Flintshire estate of Gredington into the family, served as attorney-general under both Rockingham and Pitt, became master of the rolls in 1784 and chief justice of king’s bench and a peer in 1788. A coarse-fibred man with a rough tongue, he was an able, industrious lawyer, who amassed a considerable fortune which he invested in landed property in Denbighshire and Flintshire.
Kenyon, who was admitted a member of the Brunswick Club in August 1828, was returned for Mitchell at the general election of 1830 on the interest of the Ultra Lord Falmouth.
He was in the minority of 13 for a reduction of public salaries to their 1797 levels, 30 June 1831. He divided against the second reading of the reintroduced reform bill, 6 July, for an adjournment motion, 12 July, to use the 1831 census for the purpose of determining the disfranchisement schedules, 19 July, and against the partial disfranchisement of Chippenham, 27 July. He demanded ‘as a claim of right’ that all the Welsh counties should, like Glamorgan, be given an additional seat, 18 Aug., but dropped his motion for a mandatory instruction to the committee when the leader of the Commons, Lord Althorp, promised to consider the idea (Denbighshire was later given an additional Member). He divided against the bill’s third reading, 19 Sept., and its passage, 21 Sept. Following its defeat in the Lords his father, who had recently made a fool of himself with a drunken outburst at a party meeting, was reportedly spoiling for a physical ‘fight with the people’.
At the general election of 1832 Kenyon made a bid for the extra Welsh county seat which he had helped to secure by standing for Denbighshire. He set much store by his support for agricultural protection and claimed to favour the abolition of slavery, but he was abused on account of the emoluments, totalling in excess of £9,400, which his father and uncle Thomas Kenyon derived from king’s bench sinecures. He was beaten into third place and thereafter played little part in public life.
