Perhaps this is not something to get envolved with but my understanding is that the proof must come through male descendants and Thomas Jefferson had only one daughter to live. He had no direct male descendants. The "proof" comes from some of TJ's male relatives and only proves that Hemmings had children by "a" Jefferson. Please don't write me about this I am not beating any drum one way or the other I just think we are all interested in the best accuracy we can obtain. I was in Monticello a year ago and bought "umteen" books on the subject and have read everything I could find on the internet. It is really very interesting. Shirley If this is correct, why were they able to the descendency of Thomas Jefferson? Officially if will become proof of their relationship to Jefferson and Hemmings.
