Quick Summary

A new DNA analysis adds to the body of evidence suggesting that Thomas Jefferson fathered children with Sally Hemings, an enslaved woman he owned. The investigation, detailed in Richard Kurin's book "History by a Hair," involved scientists studying strands of hair from Jefferson’s personal Bible for genetic material and comparing it with descendants of both Jefferson and Hemings. While earlier DNA tests in the 1990s confirmed a match between Jefferson’s family line and Eston Hemings, this new analysis aims to further clarify whether Jefferson or another male relative was the father. The findings continue debates about Jefferson's legacy concerning slavery and his personal relationships.

Story summary

Researchers at the Smithsonian Institution have provided "extraordinary proof" that Thomas Jefferson fathered children with Sally Hemings, a slave he owned. After 15 years of work involving archaeologists, genealogists, molecular geneticists, and historians, they compared DNA from hair strands believed to be Jefferson's with samples from descendants of both Jefferson and Hemings. The study used 20,000 simulations to analyze the paternity scenarios, finding the odds that Jefferson was not the father of Hemings' sons Madison or Eston were less than one in 1,000. This discovery adds a significant layer to debates about slavery, race, and Jefferson's legacy, as he is known for writing "All men are created equal," despite the paradoxical reality if his relationship with Hemings is confirmed.

"Thomas Jefferson wrote the most famous phrase in American history — 'All men are created equal' — and yet, if he bore children with Sally Hemings who were born into slavery, it seemed like a paradox and a contradiction," Richard Kurin told NPR's Michel Martin for Morning Edition.

New DNA analysis adds evidence Jefferson fathered children with Sally Hemings New DNA analysis adds evidence Jefferson fathered children with Sally Hemings asserted
Jefferson → add → Hemings
For more than 200 years, one question about the nation's third president has lingered: Did Thomas Jefferson father children with Sally Hemings, a woman 30 years his junior whom he held in slavery? asserted
he → linger → slavery
"Thomas Jefferson wrote the most famous phrase in American history — 'All men are created equal' — and yet, if he bore children with Sally Hemings who were born into slavery, it seemed like a paradox and a contradiction," Richard Kurin told NPR's Michel Martin for Morning Edition. asserted
Kurin → write → Edition
Kurin, a distinguished scholar and ambassador-at-large for the Smithsonian Institution, spent 15 years searching for Jefferson's DNA in an effort to answer the paternity question. asserted
Kurin → spend → question
The investigation began with strands of hair found in Jefferson's personal Bible and eventually involved scientists, archaeologists, genealogists, forensic experts and Jefferson's and Hemings' descendants. asserted
investigation → begin → scientists
The investigation's twists, as well as the science behind it, are detailed in Kurin's new book, History by a Hair. asserted
twists → detail → Hair
Allegations that he fathered children with Hemings emerged in the late 1700s and early 1800s and have been debated by family members, biographers and historians ever since. asserted
he → father → members
Kurin and his team were not the first to turn to DNA. asserted
Kurin → turn → DNA
In the late 1990s, pathologist Eugene Foster and colleagues analyzed Y chromosome markers from Jefferson's family descendants and a descendant of Eston Hemings. asserted
Foster → analyze → Hemings
"He [Foster] found contemporary descendants who had the Jefferson Y chromosome, and then he found the descendant of Eston Hemings, Sally Hemings' youngest son. asserted
he → find → Hemings
Coupling the historical evidence with that DNA evidence, it convinced, I think, most historians and a lot of people that Thomas Jefferson was indeed the father of Sally Hemings' children," Kurin said. asserted
Kurin → couple → children
