Meanwhile, for your amusement, I found this at the Smithsonian Museum of American History in their exhibit on Jefferson's slaves. This is a tree for the enslaved family of Joseph Fossett and Edith Hern, who lived on the Monticello hilltop. Originally, I took this picture because I liked the way that it represented the generations -- much better than the standard tree shape.:
Then, I noticed the grandson there at the bottom of the circle. His name?:
Frederick Douglass Issacs (1851-1904).
As I always joke with my students, all things lead to Frederick Douglass.
