Who knocked up his sister-in-law and ran off, if I remember correctly. The problem of teaching history at the middle/elementary school level was that I could never tell the really good stories.
Weren't Jefferson's mixed-blood slave concubine actually his father-in-laws biological duughter ie. his wife's half-sister?
If so, I wonder how he pulled that one off....
