Query: Gordon-Reed's unprofessional omission of Randolph Jefferson.

As the author of "The English Ancestry of Thomas Jefferson" (pub. 1996), I found it highly unprofessional that Gordon-Reed in her book omitted Randolph Jefferson, younger brother of Thomas Jefferson, who had the same DNA as Thomas, was often at "Monticello", and was a possible father of Eston Hemings. I must think that Randolph clouded the issue for Gordon-Reed so she ignored him.
