Yet what compelling biological evidence is there that Thomas Jefferson and not some other Jeffersonian fathered Eston? There is none. The biological evidence shows only that someone in Jefferson's bloodline was the father, not that that someone could only have been Thomas Jefferson or that that someone was more likely to be Thomas Jefferson than to be the offspring of any other person. In ruling out the Carrs in the paternity of Eston, one cannot simply implicate Jefferson.
