George Watson-Taylor was the fourth son of George Watson. From 1810 he was the husband of Anna Susana Taylor, the daughter of Jamaican planter Sir John Taylor, 1st Baronet. Suffixing his name with that of his wife's family, he would become the richest planter on Jamaica. He used the proceeds to purchase a house on Cavendish Square, Middlesex and Erlestoke Park, near Devizes, Wiltshire, becoming the Liberal MP for Devizes, an ardent campaigner for the retention of slavery, and a renowned fine art collector. Following the abolition of slavery his finances collapsed, and he died on 6 June 1841, in Edinburgh.
