We are aware of at least one local property owner who gained his capital from slavery, but there will be many more. Henry Thornton had land in Dominica, and when he died in 1773 his estates there were to be sold to clear the encumbrances on his several houses and garden at 'Bishops Hill the younger'. We are currently investigating this.
