I am looking for information on my grandmother, Edith Brown, whose parents might have been from the West Indies. In doing a surname search, I discovered that Brown was a surname in Bermuda. I would like to receive information on the migration of slaves from the West Indies to the United States, particulary to the South.(I.E.South Carolina, New York, Pennsylvania, and Maryland)

Brown is a very common surname, you can find it in most islands. Barbuda is not Bermuda their about as far apart as Virginia and Puerto Rico but with the minimal info you have provided it could as well be either place.
