 The test results did show a match between the Jefferson male line and the descendant of Hemings, though it showed nothing about the descendants of Sally Hemings's other children.The historian Andrew Burstein has said, "[T]he white Jefferson descendants who established the family denial in the mid-nineteenth century cast responsibility for paternity on two Jefferson nephews (children of Jefferson's sister) whose DNA was not a match.So, as far as can be reconstructed, there are no Jeffersons other than the president who had the degree of physical access to Sally Hemings that he did."
