There appear to be about as many theories as questions on the term "Black Dutch" - there is no one definition that is accepted. The most common two seem to be 1) a Germanic descendant of darker complexion or hair (as in Black Irish) and 2) descendants of the Melungeons (another mysterious people, apparently a mixture of black, white and Indian). This latter could not describe the original immigrant, but might apply to some descendants. There was a group a few years ago attempting a study on the Black Dutch. They were inviting anyone and everyone claiming Black Dutch ancestry to take part. Unfortunately, as I am becoming older and more forgetful I cannot remember who/where. If interested, you might find it mentioned on the Internet. M.A. Causey
