In 1761 Wilson was recommended at Bossiney by Thomas Pitt sen., who was making a bid for the borough, but dropped it to avoid a clash with Bute. In July he applied to Lord Egmont, who had been returned at Ilchester and Bridgwater, to succeed him in the seat at Ilchester which he was going to resign;
In 1768 he was returned unopposed at Camelford. Robinson in both his surveys on the royal marriage bill, March 1772, described him as ‘pro, sick, present’. No other vote by him is recorded, but in Robinson’s list of 1774 he appears as ‘hopeful’. Apparently he never spoke in the House.
According to Nichols’s History of Leicestershire (iii(1), p. 10) Wilson ‘passed the principal part of his life at the German Spa and other parts of the continent, and died, immensely rich, at Pisa in Tuscany’ 12 Dec. 1796.
