Anyone seen these shows, where celebrities search for information on their family history? There are many versions of the show too. I mostly just watch when there's a celebrity I like, such as Charles Dance & Julia Sawalha etc. The format of the series has proved popular around the world and the BBC has licensed it to many foreign television companies, who have produced their own individual versions: A Polish version, called Sekrety rodzinne, which was broadcast from November 2006 to March 2007.
