I know this story. He was my grandfathers grandfather (if I am remembering this correctly). The story I was told was he was left on the doorstep of a family in knoville, tennessee. The family was not named black, but the baby had a note stating his name Drury Black. The note stated that his mother was an English actress and could not care for me. I will have to see if I can find out more about this. It has been a while since I have thought about it.
