Tracking down the ancestors and researching family trees is set to become BBC Two's latest big theme.
The channel launched its autumn schedule on Wednesday, describing its centrepiece show as being "television's biggest ever family history initiative". The programme "Who Do You Think You Are?" will feature 10 celebrities, including Jeremy Clarkson, Vic Reeves and David Baddiel, researching their backgrounds.
In addition, the show aims to help the public track down their own family tree.
