Who Do You Think You Are: Season Two premieres on Friday, February 4, at 7 pm. on NBC.
The series follows a different well-known and popular celebrity each week as they trace their family trees. Each episode will reveal surprising, inspiring and sometimes tragic stories that are often linked to events in American and international history.
As each celebrity discovers†his or her†unknown relatives - most of whom overcame hard times - the show will take viewers back through world history to expose how the lives of everyone's collective ancestors have shaped our world today.
