Lewis Devisme (25 September 1720 – 4 September 1776 Stockholm, Sweden) was a British diplomat.
Family
Christened on 7 October 1720 at the French Huguenot Church of St Martin Orgar in Martin Lane, Cannon Street, London, Lewis Devisme was the fourth child and third son of Philippe de Visme, a successful City merchant, by Marianne de la Mejanelle his wife. Ostensibly, he appears to have been named after his godfather, Louis Ragueneau de la Chainaye, but his father may have had his own uncle, Louis de Visme of Gouy L'Hopital in Picardy, at the forefront of his mind when he came to think of a name for his new son.
Lewis's father Philippe was a Huguenot refugee who had been born in Gouy L'Hopital in September 1687, third son of Pierre de Visme and Marie Le Roy. He emigrated to London at some time before his naturalisation by Oath Roll in January 1710, perhaps being joined by his elder brother, Pierre or Peter de Visme, shortly before the latter was naturalised by an Act of Parliament in July 1717. Philippe was married by special licence at the Spring Gardens Chapel in the Strand on 26 July 1716, and together Philippe and Marianne had a total of 13 children.
