Historians Got Thomas Jefferson Wrong for 200 Years. Here's What DNA Found.

Historians Got Thomas Jefferson Wrong for 200 Years. Here's What DNA Found. For two hundred years, the Hemings family said Thomas Jefferson was their ancestor. Historians said otherwise. In 1998, a team of geneticists published a Y-chromosome study in Nature — one of the most prestigious scientific journals in the world. The results didn't suggest a connection between Jefferson and the children of an enslaved woman named Sally Hemings. They proved one. This video examines what the DNA evidence actually showed, what it couldn't prove on its own, and why the gap between those two things tells us something important about history, power, and whose family stories we choose to believe.
