It is fictitional, as is much of the Melungeon information that is out there now that proclaims it factual.
What is not understood is that my Adkins ancestors are the ones claimed to be Melungeon, by first and last name, location, etc. (so I am not just whistling Dixie here to hear a good tune), as are most of those mentioned, in most of the text found. Still they have you believe in surname connections, but say “if they fit”, however they will throw one of my ancestors in and say he was. Everyone they mention is, “isn’t”. It is a mularky. IMO
