On the Enloe front, you may be interested in Abraham Enloe of Bostic NC, who may have been Abraham Lincoln's natural father. The color there is thought to come through a Cherokee grandmother... though in those days a lot of folks got lumped together as "black." Photo is of Lincoln, who was often described as swarthy, and Enloe's son Wesley. Thomas Lincoln was a stocky 5'5" and pasty white :-)
