A new Study raises the Possiblity that Thomas Jefferson was part Jewish.
Michael Hammer, a geneticist at the University of Arizona, said he had compared the Jefferson Y chromosome with those in his database of Y chromosomes and found close matches with four other individuals. There was a perfect match to the Y chromosome of a Moroccan Jew, and matches that differed by two mutations from another Moroccan Jew, a Kurdish Jew and an Egyptian.
Dr. Hammer said he would “hazard a guess at Sephardic Jewish ancestry” for Jefferson, although any such interpretation was highly tentative. Sephardic Jews are descendants of those expelled from Spain and Portugal after 1492.–NYT
