Hi Natasha,  I'm also of mixed race, live in england and my farther comes from a small village in jamiaca near a town called Lluidas Vale in St. Cathrine.  I am also told that the Maxwell family originated from scotland but like you say it is very hard to trace how the maxwells got to jamiaca? You may have progressed some what with your search by now? However if you have any queries please dont hesitate to ask me. Also I would be very interested to know any of your finding.
