Hi Marilyn,
Believe it or not, I missed it too but my daughter-in-law recorded it so was able to see it on the big screen.
This week was Matthew Broderick (I didn't know he and Sarah Jessica Parker were married).
Anyway, it was another interesting episode, and without spoiling it for those who haven't yet seen it, Matthew didn't know anything about his father's family so set out to see what he could find. Turns out his grandfather was a WW1 hero, his grandmother was an orphan and I think it was his grandmother's father who fought in the Civil War and lots of little bits and pieces along the way. It had a lovely ending.
My feeling was that he was like most of us and was thrilled and fascinated with each piece of the puzzle.
Like Sarah mentioned, it's viewable on the Internet, so you can still see it.

Enjoy!
