I guess I am playing catchup here. I announced on this blog in November that NBC was renewing the series, "Who Do You Think You Are" for a third season. But the announcement of who the featured subjects would be got by me earlier this month.
I am providing the NBC press release in its entirety below. As you will see, there are twelve subjects listed in the news release, and the trailer provided on the WDYTYA website (courtesy of NBC) at http://www.nbc.com/who-do-you-think-you-are/ contains clips taken from several of the forthcoming episodes. Enjoy. I know I will.
