Scottish slaves in America.
My husband’s family is descended from John Cragin (sometimes spelled Craggin) who was one of the Scots prisoners. The story is he contacted smallpox aboard ship and was in danger of being thrown overboard but a young girl Sarah Dawes pleaded for his life and agreed to nurse him to health. Some years later the two were wed.
