Input: Article: In July 2012, Ancestry.com reported on historic and DNA research by its staff that discovered that Obama is likely a descendant through his mother of John Punch, considered by some historians to be the first African slave in the Virginia colony. An indentured servant, he was "bound for life" in 1640 after trying to escape. The story of him and his descendants is that of multi-racial America since it appeared he and his sons married or had unions with white women, likely indentured servants and working-class like them. Their multi-racial children were free because they were born to free English women. Over time, Obama's line of the Bunch family (as they became known) were property owners and continued to "marry white"; they became part of white society, likely by the early to mid-18th century.

Now answer this question: Who is Obama possibly an ancestor of?

Output: John Punch
