‘Black Billy’ Holmes was the son of a well-to-do Irish brewer. He entered the army and served in the West Indies, acting as military secretary to Sir Thomas Hislop. He left the army in 1807 and in March 1808 contested Grampound on the interest of Basil Cochrane. He was defeated, but obtained the seat on petition. On 21 Oct. 1808 Huskisson informed Spencer Perceval that Holmes was a ‘sworn friend’ of Charles Palmer.
Subsequently Holmes was a reliable supporter of Perceval’s administration. In January 1811 he was a dining friend of the premier’s and about that time obtained a place in Jamaica worth £2,400 p.a. for one of his brothers. He could be counted on to oppose sinecure reform, 21, 24 Feb., 4 May, and voted against a stronger administration after Perceval’s assassination, 21 May 1812. He was a go-between in the bid to bring Canning into Liverpool’s cabinet in July 1812. At the ensuing election he stood no chance at Grampound, but was returned after a contest at Tregony, where the Treasury and Lord Yarmouth assisted him against Lord Darlington. According to Andrew James Cochrane Johnstone, Holmes’s disgruntled running partner at Grampound, they received no government assistance and did not solicit it: and he denied the Prince Regent’s assertion, put about by his secretary McMahon, that they had. He claimed that ‘McMahon did everything to encourage a rupture between Arbuthnot and Holmes, but Arbuthnot has most completely exonerated himself from all blame, and has fixed the lie where it originated’. Arbuthnot (secretary to the Treasury) was very embarrassed: he had assured the Regent that Johnstone and Holmes were friendly to government, but he now declared that ‘the loss of men like them will never materially injure any government’ and affected to be ‘very amused’ to learn that Holmes was his first cousin: ‘till I got acquainted with him in the House of Commons I did not know of his existence, and having always thought him a very vulgar low sort of man, it has been my unwearying endeavour to stand aloof from him’. On 8 Nov. George Rose wrote to Arbuthnot after a scrutiny of the list of new Members, ‘Holmes is marked pro in the last Parliament and con in this, for which I suppose you have good reason’. Next day Canning wrote of Holmes that he was brought in by Lord Yarmouth ‘but he will be with me as far as he dares’.
Holmes lacked the audacity with which Canning credited him. He voted against Catholic relief, 2 Mar., 11 and 24 May 1813, and again in 1816 and 1817. (He opposed it to the end.) The Irish secretary paid him this compliment, 26 May 1813: ‘He knew the House perfectly well and the manner in which almost every man in it would vote— indeed I may [say] every man of those that did vote or paired off’.
At the dissolution of 1818 Holmes was awarded the treasurership of the Ordnance, Lord Mulgrave being informed that a Member of the House was wanted for the place. He then came in for Totnes, probably on the Farwell interest, though Aldeburgh was also thought of for him. His duty henceforward was to act as Treasury whip: Henry Bankes described him in May 1819 as ‘our great calculator upon relative numbers’. For this he was well qualified, as he ‘seemed to know every collateral relationship in blood and politics of those he had to whip up’.
