I've got the shovel teeth and the lump, but I can explain that by the strong possibility that one of my great grandmothers was Melungeon. She was born in the right part of Kentucky, had olive skin, and blue eyes. But my dh also has shovel teeth, and his ancestry is German & Swedish, with no historical links to the Appalachians. His Swedish half is pure, as they were recent immigrants to the US. But maybe there is a little mixture with American Indian the German side, given that they were here before the Revolutionary War so there would have been time for that.
Isn't there an ancient Swedish/Asian connection, or am I dreaming that?
