Researchers have completed a 15-year investigation into the paternity question surrounding Thomas Jefferson and Sally Hemings, using DNA analysis to provide additional evidence on the matter. The inquiry, led by Richard Kurin, a distinguished scholar and ambassador-at-large for the Smithsonian Institution, involved scientists, archaeologists, genealogists, forensic experts and descendants from both families. The central question has been contested for more than 200 years, with particular significance given Jefferson’s role as principal author of the Declaration of Independence and his famous phrase that “all men are created equal.”
Previous DNA testing in the late 1990s by pathologist Eugene Foster examined Y chromosome markers and identified contemporary descendants carrying the Jefferson genetic signature, as well as a descendant of Eston Hemings, Sally Hemings’ youngest son. However, some observers noted those results could theoretically point to any male relative of Jefferson. The current investigation drew on expertise in ancient and paleogenomics, with researchers working to obtain Jefferson’s own genetic material to provide more definitive answers.
A critical breakthrough came after about five years when the team discovered that hair strands initially believed to be Jefferson’s were not. Kurin subsequently located a packet of hair labeled as having been cut the day Jefferson died, July 4, 1826. Analysis of this sample yielded viable DNA that allowed researchers to sequence Jefferson’s genetic profile for comparison.
The new findings indicate that descendants of Madison Hemings and Eston Hemings, Sally Hemings’ two youngest surviving sons, possess substantial amounts of Jefferson DNA. Some Hemings descendants were found to carry more Jefferson genetic material than known Jefferson descendants. Researchers were unable to locate descendants of Sally Hemings’ other surviving children, Harriet and Beverly Hemings, who left Monticello in 1822 and subsequently passed as white in Washington, D.C. Kurin plans to make Jefferson’s genome publicly available to assist others in tracing family connections, with a scientific paper currently under review for publication.
