Sorry Its taken me so long to reply. Can you email me back with some specifics on how you are related to the Hunters from Cayman Brac, because I do have extensive info on that family tree, however, I don't see the names you ask about. I am almost positive there was only one family of Hunters from Cayman Brac, my great-grandmother is 1 of 8 children. Her parents were Joseph Rufus Hunter and Angeline Topping. Joseph was 1 of 9 children. His parents were William Armstron Hunter(b. 1826) and Mary Catherine Watler(b.1827).
Williams parents were James Wood Hunter(b.1803) and Mary Ann Parsons(b.1811). Williams parents were William John Hunter(b.1763) and Elizabeth Rachel Wood(b.1772).
