This companion Website to the recent broadcast of the Frontline documentary "Jefferson's Blood" is unusually rich in content, perhaps because it was used post-airing to feature Frontline's presence on the Web. Exploring the history and current controversy over Jefferson's longtime relationship with his slave and mistress Sally Hemings, the site features video excerpts from the broadcast; extended documentation of the DNA debate over Jefferson's extant ancestry; memoirs of four of Jefferson's slaves; essays and interviews from well-known Jefferson scholars, such as Joseph Ellis and Annette Gordon-Reed; discussions by sociologists, historians, and journalists of the nation's historical response to mixed ancestry and its threat to the white mystique; annotated links to premium Jefferson Websites; a teacher's guide; and a good deal more. The site admirably confirms that, when it comes to the question of race in America, there are few historical narratives more telling or more complicated than the one Thomas Jefferson wrote in his own blood.
