I've been watching a few of the British
Who Do You Think You Are? shows and they are so much better than the American version it's hard to believe they're even related. They are packed with information instead of constantly repeated summaries and there isn't a single plug for subscription genealogy sites. The three that I've watched so far don't go back very far, but rather focus on a fairly close circle of relations who are of particular interest to the celebrity.
My favorite so far is Emilia Fox, aka Georgiana Darcy from the Colin Firth
Pride and Prejudice. Her family history is fascinating and her living great aunts are priceless, especially the blind, half-deaf who was 103 years old when this was filmed.
