Last year, CBS News producer Rodney Hawkins shares the story of his family's efforts to restore a nearly 200-year old ancestral cemetery in East Texas. Almost a year after beginning the progress, Hawkins is back with an update. Talking with "CBS This Morning Saturday" co-host Michelle Miller, Hawkins explains how he was able to dig deeper into his family's past with the help of the Lone Star Slavery Project at Stephen F. Austin State University. And what's next for him and his family on this journey.
