No, but it has proven that Jefferson fathered at least some of her children. Not to mention he granted freedom to her children while the rest of the slaves at Monticello were sold off to settle his debts.
Except the other males in her family didn't own her, didn't travel to France with her, and didn't grant her children freedom after he died. That was all him. Not to mention the affair was widely reported in the press at the time... even satarized in newspapers.
Wow... wrong again. By the time Jefferson took Hemings as a sex slave, Martha Wayles Jefferson had died in 1782. Jefferson took the then 15 year old Hemings to Paris with him when he was appointed Minister to France.
Fun fact, Hemings was 7/8 white, and her biological father was the father of Jefferson's wife. Which is why the fact he was raping her and not any other member of the Jefferson clan makes even more sense.
