Speaking of Andrew Johnson, Lincoln's VP, his wife (common law, I believe)was a black lady and all his kids were of mixed ancestry. The lived a noraml life, to the extent that any politician could or can. There's an interestin. book called "Creeks and Seminoles" by Leitch Wright that spends a couple of pages on Johnson. A popular man of his times, but that was then and now is vastly different.
