President Obama’s extraordinary family story gained a new layer this week as a team of genealogists found evidence that he is most likely a descendant of one of the first documented African slaves in this country.

The link to slavery, which scholars of genealogy and race in the United States called remarkable, was found to have existed approximately 400 years back in the lineage of Obama’s mother, Stanley Ann Dunham. It was discovered by a team of four genealogists from Ancestry.com whose findings from two years of work were released in a report Monday.
