The Riley family of Sand Mountain has been traced back to Sean O'Reilly of Northern Ireland in the 1500s. The emigrant Samuel Riley (about 1720-1792) married Nell Wallace in Maryland. Their children were named Samuel, Eliphas, Elizabeth, David Moses, Milcah, Margaret, Darby, Susanna, Edward, George, and James. Samuel Riley, Cherokee Indian merchant and interpreter, married two daughters of Chief Doublehead and received a 640 acre reservation on south side of the Tennessee River opposite Southwest Point, Roane Co., "by right of wife" in 1817, but when Tennessee took back all Indian reservations, he moved to Sand Mountain in Alabama. Doublehead had important connections with the area around Yahoo Falls on the Cumberland River in Kentucky. He was born in Stearns, in what is now McCreary Co. Tuckahoe Doublehead, his son, married Margaret Mounce, and he himself took as one of his wives Nannie the Pain Droomgool, the daughter of Scots trader Alexander Droomgool, whose extensive possessions appeared on the list of valuations as published by an act of Congress, 1837. Many years later, Alexander Droomgool's descendant, a Nashville journalist, invented, or at least popularized, the term Melungeon at a time when her cohorts among New York travel writers were inventing "hillbillies" (Benjamin Albert Botkin, A Treasury of Southern Folklore [New York: Crown Publishers, 1949], pp. 85-86). She placed the last remnants of the Melungeons on Newmans Ridge in Tennessee, oblivious of their migrations to other parts of the country during Indian Removal.
