I've been doing some research on an ancestor of mine, William Leeman. William was sailor,and according to his obituary was born in Jamaica, the son of a plantation owner. Later on William settled down in New York. I am trying to track down his Caribbean origins -- on some of his census documents in New York list "Casso, WI" (West Indies) as his place of birth.
I've done some research but not been able to find either a city\province in Jamaica or and island referred to as Casso.
Has anyone head of Casso?
