I think this will be a great episode to check out. If you are familiar with SJP, you know she’s a family gal all the way. She grew up in a large family and traveled regularly with her mother for acting gigs. She seems to have a genuine interest in family, so it will be interesting to see what she finds out. Who Do You Think You Are? airs tonight at 8pm EST.
