The program, hosted by Henry Louis Gates, searches through the ancestries of notable individuals in order to elucidate the past.
When it comes to Affleck's ancestry, it seems one of his forebears was a slaveowner. What's more, the embarrassing information was not included in the episode at Affleck's request.
