Now in its 15th series, the genealogy series shows no sign of stopping any time soon.
The first celebrity looking back into their family tree is actress Michelle Keegan, who is an apt choice given the role of women in her family, as this year marks the centenary of women’s suffrage. She learns about her great-great-grandmother’s connections to Emmeline Pankhurst, and also about her great-grandmother who was evacuated to Gibraltar during World War Two.
Who Do You Think You Are? is on BBC One at 21.00.
