Williams’s father and namesake, a self-made man, was descended from a cadet branch of the Williams family of Herringston, Dorset, and married the daughter of a French Huguenot refugee. He became a leading London banker and a director of the East India Company, purchased estates in Dorset and Hertfordshire and secured a seat at Dorchester in 1807. This Member, the elder of his two sons, had a brief spell on the corporation of London and in 1802 entered the Commons, where he was an almost silent supporter of successive Tory administrations.
Williams voted against economies in revenue collection, 4 July 1820. He divided in defence of ministers’ conduct towards Queen Caroline, 6 Feb. 1821. He is unlikely to have been the ‘R. Williams’ who was listed as voting for revision of official salaries, 30 Mar.; he divided against repeal of the additional malt duty, 3 Apr., and Hume’s motion for economy and retrenchment, 27 June 1821. He voted against more extensive tax reductions to relieve distress, 11, 21 Feb., and abolition of one of the joint-postmasterships, 13 Mar., but was credited with dividing for inquiry into the duties of the officers of the board of control, 14 Mar. 1822. He wrote offering his backing at the forthcoming Dorset by-election to the Tory Henry Bankes*, 10 Feb. 1823.
The following week he wrote from Bridehead to Peel, the home secretary:
I find a great inconvenience in having two large places in the country, without time to be as much at either as I should wish, and have therefore thought of parting with one. This is my native county, and a favourite residence to myself and family, and, having lately added much to its extent by a large purchase and opportunity occurring of more, I have made up my mind to sell Moor Park and its appendages, which are, an estate in a ring-fence of about £5,000 per annum, exclusive of the park (500 acres), a large farm in hand and some fine woodlands. The house is very magnificent, fit for any man’s residence ... [and] 17 miles from Oxford Street.
Peel declined to make the purchase and it was soon afterwards sold to Lord Grosvenor.
Williams voted against Catholic relief, 6 Mar. 1827. He may have been the ‘Mr. Williams’ who spoke in defence of the board of lunacy, 19 Feb. 1828. He divided against repeal of the Test Acts, 26 Feb., presented a Dorchester anti-Catholic petition, 24 Apr., and again voted against Catholic claims, 12 May. In February 1829 he was listed by Planta, the Wellington ministry’s patronage secretary, as likely to be ‘with government’ on Catholic emancipation. In fact, he presented another anti-Catholic petition from his constituents, 3 Mar., and divided steadily against emancipation that month. He voted against Jewish emancipation, 5 Apr., 17 May 1830. He was returned unopposed for Dorchester, on the basis of his long service in defence of the principles of the constitution, at the general election that year.
He voted against the second reading of the reintroduced reform bill, 6 July, and, despite being granted one month’s leave because of a death in the family, 12 July, divided in favour of using the 1831 census to determine the boroughs in schedules A and B, 19 July, and for postponing consideration of the partial disfranchisement of Chippenham, 27 July 1831. He presented and endorsed a Dorchester petition for retention of both its seats, 28 July, when he admitted that at the time of his first election he had not owned a single house there. He divided against the passage of the bill, 21 Sept. He voted for Ashley in the Dorset by-election that autumn.
