'Who do you think you are?' premiere: 'Desperate Housewives' Vanessa Williams hunts for answers


We're really excited about the return of "Who Do You Think You Are?" on NBC. If you haven't seen it, the documentary series follows celebrities in their search to answer questions about their family. 

Many times it leads to big realizations that change the way the celebrity looked at their family, a family member or themselves. Sure, it sometimes seems like an infomercial for Ancestry.com, which they use heavily to find family records, but we also love meeting local historians who have dedicated their lives to knowing their town like the back of their hand. Plus, it really makes you wonder about your own unknown family history.
 
In the premiere, "Ugly Betty" and "Desperate Housewives" star Vanessa Williams tries to unravel some mysteries about her great great grandfather's side of the family.

Watch a preview below:



"Who Do You Think You Are?" premieres Friday (Feb. 4) at 8 p.m. ET on NBC.
