I thought they never proved that Jefferson and not his hellion nephew(s) fathered those children?

It's funny you mention this. The place acts like it was 100% fact that Jefferson fathered Hemmings' children.

Then, buried deep into a written exhibit, there were these interesting bits:

1. the first mention of the Jefferson/Slave Affair was written by political opponents running against Jefferson in the 1800 election. It was used to slander him.

2. It was common practice for guests to sleep with slaves. Buried even further was this: Thomas Jefferson's brother Randolph had close relations with the slaves of Monticello - to the point that they referred to him as "Uncle Randolph."

3. The DNA used proved that one child born of Hemmings was a Jefferson. However, Monticello was frequented by many Jefferson males. The DNA match was never made directly to Thomas. It was linked to a "male Jefferson."

4. All of this counter-evidence was disregarded because "Thomas Jefferson was the most likely candidate."

Also, there was an exhibit that heavily implied Jefferson raped Hemmings. The entire rationale for this was "Hemmings couldn't consent. She had no rights."

So not only did Monticello bend over backwards to make Jefferson the father of her children - he was also her rapist.

I cannot explain to you how angry I was when I left Monticello. They completely disgraced him in his own home.

Only a liberal hellhole could do something like that to one of the most intelligent, patriotic, visionary men to grace this planet.
