I also found my way here from apost on the Melungeon board and hope that this might help someone.
I don't know if the Adkins were considered 'Melungeon' or Indian or if there is a difference, but the name is associated with the 'people who were called Melungeons' so it is likely they were Indian and 'some' may have married into those 'Melungeon families'.
Walter Plecker included the ADKINS name from New Kent which was the early home of the 'Melungeon Gibsons, Collins, Bunch, etc.From MELUNGEONS; EXAMINING AN APPALACHIAN LEGEND by Pat Spurlock Elder; "Rountree identifies Adkins as most commonly found among the upper Mattaponi." http://www.geocities.com/ourmelungeons/plecker.htmlhttp://www.geocities.com/ourmelungeons/plecker.html
In 1947 George Washington Osborne said this of the Adkins family;
"The Adkins family of Indian origin came from Blackwater, Tennessee. Some of them have migrated from Scott County to Letcher and Pike County....
...........I have separated the Melango families into the different groups as follows:
Many of the 'Melungeon families from Hancock County, Tenn, Scott Co., Va., etc.. migrated to Letcher, Floyd, Morgan, Magoffin, etc., counties in Kentucky and then on to Ohio.
See Adkins at this page;
"Early in 1905 (some say 1906) at least forty-two families mostly in Morgan and Magoffin Counties of eastern Kentucky sold their land, packed a few household items and personal goods, loaded into wagons, and went to the nearest train station. They chartered the entire train and went west to Ardmore in the Chickasaw nation of Indian Territory." http://rootsweb.com/~kyjohnso/IndianTrainride.htmhttp://rootsweb.com/~kyjohnso/IndianTrainride.htm
