Here is a link to the "bible" of the new effort to earn about the Melungeons.
it is written by N. Brent Kennedy, a resident of Wise Virginia who ended up in Emory hospital in Atlanta where he learned he had a rare hereditary disease limited to Mediterranean people. He was astounded because he was from Wise....Southwest Virginia. I attended one of his lectures and have been interested ever since.
The result was his book "The Melungeons" The Resurrection of a Proud People. It is the basis for tremendous work that followed.
Here is a good link with many family names.

I would also check out the Kingsport Times news website archive. They have periodic articles and cover very well the annual homecoming event that has taken place in recent years. The children and grand children are very curious about their mountain/ridgetop heritage and are coming together into the open to study and learn.
As a pure outsider but Tennessee resident and property owner in Claiborne County , a Mulengon stronghold, I was curious. This curiosity was compounded when I was able to tie Melungeons into the Lost Colony on Roanoke Island a favorite vacation spot with "The Flamingo Feather" a favorite book that is set near Cumberland Island Ga another favorite vacation spot. The Melungeons are unquestionably descendents of these early failed colonial efforts
Not too long ago I searched for Kirk Monroe on the Kansas geneological registry to find out how an author in the 1800's in Kansas had such a good feel for the precolonial effort in Georgia. I never learned but now get periodic inquires about the monroe family because somehow I'm known there. :)
