John Trevanion

1740 - 1810


London merchant, MP for Dover 1774-1784 and 1789-1806, and son-in-law of Sir John Boyd 1st bart. of Danson Park. Trevanion was shown as an owner in Grenada c. 1780. In 1817 Camden Park estate in St Vincent was registered to the heirs of the late Sir John Boyd and John Trevanion. Trevanion also appeared as a mortgagee with William Wood of property in St Vincent of Charles Payne Sharpe (q.v.) in 1766 for £5000.

  1. According to the History of Parliament, '[t]he nature of the business which Trevanion conducted from South Sea House, Broad Street, where he was listed as a merchant in the London directories between 1781 and 1795 (having previously traded from addresses in Bishopsgate), is not clear, but in 1806 Charles Jenkinson, who opposed him at Dover on the lord warden’s interest, described him as ‘originally a West Indian’. Jenkinson went on to say that ‘he has dissipated whatever property he possessed and bears in other respects a very broken reputation’.'
