Southern Virginia will be featured on a new reality TV series Friday night, "Who Do You Think You Are?" (8pm, NBC).  Emmitt Smith, the NFL's all-time leading rusher, was in the area last spring  to film the show, which traces his ancestry back to a horse and slave breeder in Mecklenburg County.  During filming Smith stayed at Berry Hill and a number of the interviews that will appear in the show were filmed at there.  For more information, read the article on the News & Record's website.
