It's the turn of The Great British Bake Off's Mary Berry to trace her family history tonight, and she's determined to find out where she got her go-getter energy from. Hardly the most exciting search they've ever made really. She travels to Bath where she grew up, along with Norwich, where her grandparents lived. Along the way she uncovers ancestors including a bankrupt book-binder, a self-motivated corset-maker and a third who worked in a much more familiar profession. And if Mary Berry doesn't float your boat, you can watch Annie Lennox do much of the same over on RTE 1 later.
