How does the Ottoman Empire relate to Melungeons?

Any serious researcher of early American history should read this eye opening book written by the late professor Joseph M. Scolnick (1940-2005) and N. Brent Kennedy. Professor Scolnick was teaching at the University of Virginia’s College at Wise until he passed away in December 2005. I met and talked to him at a Melungeon Gathering in Kingsport, TN and listened to his lecutre.
