Melungeons is very close to the name Merovingians, who according to legend, were keepers of the Holy Grail or possible descendants of Jesus Christ.
Whoa....do I smell a conspiracy! These black-haired, blue-eyed people could really be the descendants of Christ. < /sarcasm>
Are you telling me the Holy Grail could be in Eastern Tennessee buried next to Buddy's BBQ & Tack Shop? Wouldn't that be something!
OK, I'll claim my Mulengeon roots now.
