BBC One

Genealogy series in which well-known people trace their family tree, often travelling to different areas and other countries to follow in their ancestors' footsteps. Family secrets and forgotten stories are revealed, sometimes confirming the celebrity's previous ideas, but often completely subverting their expectations as tales of bravery, charity, loss and heartbreak come to light. Past participants include Bill Oddie, JK Rowling, Graham Norton, Nigella Lawson, Jeremy Irons and Patrick Stewart.
