HERONS OF GALLOWAY (Scotland), IRELAND, AND JAMAICA (West Indies)

I was wondering if you knew if Ivan Soloman Heron was related to these herons. There were 4 brothers LLoyd, Ivan, Clinton & Keith.I cannot remember His Parent s name,but they lived in Christiana Jamaica. Ivan wouod have been bon around 1915 or so and was married to Annie Daphne Hill.do you know where I can find info on this?
