Thinking about dabbling in genealogy? Many baby boomers are. You are in luck. NBC is launching "Who Do You Think You Are?" at 7 p.m. Friday, March 5. Expert genealogists will find out amazing ancestors of Sarah Jessica Parker, Susan Sarandon, Spike Lee, Mathew Broderick, Brook Shields, Emmitt Smith and Lisa Kudrow.

We've been watching another show, "Faces of America with Henry Louis Gates Jr.," on PBS. The show's host goes to great lengths to track down the family trees of Meryl Streep, Yo-Yo Ma, Queen Noor, Kristi Yamaguchi, Eva Longoria, Mike Nichols and more. You can catch the last episode at 7 p.m. Wednesday, March 3, on AETN. Most likely the station will re-broadcast the show so watch the listings. You don't want to miss this.
