Jefforson's biographers treated him much too kindly. Edwin Betts ran across proof of Jefferon's slaves being beaten in the nailery on Mulberry Row and hid the evidence rather than report it. Several sources refer to the agreement that Sally had with Jefferson to free her children when that became of age if she returned. Sally was not automatically free in Paris, she would have had to have petitioned for her freedom against one of the most powerful men in the world. Sally's agreement wasn't in writing like that of her brother James but according to multiple sources it was real. Jefferson could have welched on his agreement with James, Sally, and never freed any of her family without repercussion.
