William Trelawny, by order of his uncle Harry, applied to Henry Pelham ‘as a person who from the natural interest of my family and the goodwill that is borne to it at the two boroughs of East and West Looe, had very good pretensions to offer myelf as candidate for a seat in one of those boroughs at the ensuing election [1754]’. Pelham admitted his claim, but the candidates had already been settled with Governor Trelawny—if he now acceded to that arrangement, Pelham would support him on the next vacancy; and ‘in the mean time he said he would take care that I lost no ground in my profession by making him that concession’.
Newcastle, on succeeding Pelham, was acquainted by Francis Gashry with the Trelawnys’ ‘generous concurrence in the plan agreed’, and Pelham’s engagements to them;
As promised, Trelawny was returned on the first vacancy at the Looes; and was re-elected unopposed in 1761, ‘solely by Mr. Buller’s interest’.
Many he thinks are to be influenced by Government ... and whatever may be said by any friends of Mr. Buller’s, Sir William does not at all doubt but that ... they are in general well inclined to the Trelawny family or perhaps more so if properly supported by Government than to any other, and Sir William is and always will be ready to obey any commands Sir Harry, may have for him.
And Grenville wrote to Bute, 21 May, that while ‘it may be difficult to give the assistance desired early enough, there seems to be no particular reason ... to dissuade Sir William Trelawny from trying his interest, if he thinks he can make anything of it’.
Trelawny appears in Fox’s list of Members favourable to the peace preliminaries; and was marked by Jenkinson in the autumn of 1763 as ‘pro’, but voted against the Government over general warrants, 15 and 18 Feb. 1764. On 10 May he was classed by Newcastle as ‘doubtful’; by Rockingham as ‘pro’ in the summer of 1765, and as ‘doubtful’ in November 1766; and by Newcastle as ‘Administration’ on 2 Mar. 1767—there seems to have been some connexion between him and Shelburne.
When he died in Jamaica, 11 Dec. 1772, the House of Assembly ‘immediately voted a magnificent funeral’ at the public expense to testify their grateful respect of his merit.
