DNA Study Adds Evidence That Thomas Jefferson Fathered Children With Sally Hemings
A new DNA analysis provides further evidence that Thomas Jefferson fathered children with Sally Hemings, an enslaved woman at Monticello. Researchers compared DNA from a hair lock believed to be Jefferson's with samples from Jefferson and Hemings descendants, finding genetic links to Hemings' sons Madison and Eston. They reported less than a 0.001 percent chance that Jefferson was not the father of both, based on Smithsonian research conducted over nearly 15 years.
The analysis compared DNA from a hair lock believed to be Jefferson’s with samples from descendants of Jefferson and Hemings. It found genetic links to Hemings’s sons Madison and Eston, with the researchers putting the chance that Jefferson was not their father below 0.001 percent.
Smithsonian scientists conducted the work over nearly 15 years. It adds further evidence that Jefferson, a US president, fathered children with Hemings, an enslaved woman at Monticello. The Independent has additional coverage.
This finding may affect descendants of Jefferson and Hemings, as well as historians and visitors to Monticello, by reinforcing a contested family history. It could influence how textbooks, museums, and public discussions present Jefferson’s private life and the realities of slavery. Genetic evidence may also shape debates about how such historical claims are verified, though it cannot resolve every question about consent, power, or memory.
