> Eston had male Jefferson DNA, not female.
I know. I pointed that out myself in the post — “a Carr (who had Jefferson blood from a female parent, not a male)”. No DNA tests, though, rule out the Carrs as fathers of some or all of the other children.
Interestingly enough about the Carr brothers: one lived in Maryland. That puts him out of the loop for the most part.
But the other one was thought to have a mulatto concubine who ended up with a 100 acre plot of land carved right out of the middle of the Dabney/Carr land. It was known as “Free State” and was home to many free people of color and mulattos.
