This message just received from Suzanne Russo at Ancestry.com. I am glad to see that at least some are being repeated. 

“As you may have already heard, NBC is planning to re-air four episodes of the Who Do You Think You Are? series starting on Friday, August 13 at 8/7c.

As a sponsor of NBC during the show, we wanted to make sure that you didn’t miss this Friday night affair, where you can expect to see the repeated episodes that feature Lisa Kudrow, Sarah Jessica Parker, Emmitt Smith and Brooke Shields.

For those of you who may have missed a few episodes of this family history-focused series, now’s your chance to experience it. You’ll see the celebrities take an amazing voyage to discover more about the ancestors who came before them. Or maybe you’ve already seen all the episodes. If that’s the case, it will still be worth the time to pop some popcorn and sit back to relive the heart-warming journeys that each of the celebrities experienced.

So don’t forget to tune-in to the reruns of Who Do You Think You Are? starting on Friday, August 13 at 8/7c and enjoy the show!”
