During the early years of Barack Obama's presidency, the Commander in Chief had an ally in billionaire business man Warren Buffet. In 2009, Ancestory.com revealed the two were related, as Mareen Duvall - who lived in Maryland - was Buffett's sixth great-grandfather and Obama's ninth great-grandfather. The site wrote of their findings, "We've all watched President Obama and Warren Buffett's ongoing association, from Buffett's official endorsement of Obama's 2008 presidential campaign to their sometimes differing views on economic policy. Like most family members, the President and Buffett may not always agree on everything, but this latest discovery confirming they are related may shed light on why the two seem to see eye-to-eye on many issues."
