The above identification of this elusive Member seems the most likely. Simpson was returned for Mitchell on the interest of Sir Christopher Hawkins, who vacated his seat for him. To judge by a letter from Hawkins’s agent Middlecoat, 12 May 1799, he had shown an interest in buying Richard Barwell out of Tregony, with a view to coming in there. It looks as if Hawkins came to terms with him to give himself a free hand at Tregony. Even so, Simpson threatened to intervene at Grampound, in favour of his business partner Cuthbert, on a vacancy in 1800, and Hawkins brought himself in there to forestall the bid.
Simpson appeared at his Charlotte Street address in the directories between 1793 and 1803. There is no evidence that he moved elsewhere and he was probably the John Simpson esq. who died at his house on Stamford Hill, 8 June 1803, and whose will indicates a Scottish background. He was then a merchant in partnership with Crawford Davison (his nephew) at Warnford Court, Throgmorton Street, London (previously at Hatton Court. Threadneedle Street) and referred to his ‘many years’ care and industry’.
