Love this show about genealogy because it inspired me to research my family. When NBC's genealogy series Who Do You Think You Are? returns with its third season Feb. 3, a new crop of celebrities will explore their family history. Martin Sheen, Marisa Tomei, Blair Underwood, Reba McEntire, Rob Lowe, Helen Hunt, Rita Wilson, Edie Falco, Rashida Jones, former NFL running back Jerome Bettis, Jason Sudeikis and Paula Deen will be featured on the series executive produced by Lisa Kudrow and Dan Bucatinsky. â€œWe're very excited about the stories we have this season," Kudrow and Bucatinsky said in a statement announcing the news. "This fantastic group of people we have will take us to countries we haven't visited before which is thrilling and gives us glimpses into crucial details of history that not only shaped their families, but our world. This is what we love about this series; it's so enriching for us the viewer, as well as the participants and their families.â€ Who Do You Think You Arefeatures a different celebrity tracing their family history each week with assistance from Ancestry.com in researching participants' family roots. Previous contestants have included Sarah Jessica Parker, Kudrow, Rosie O'Donnell and Steve Buscemi.
