Greg Davies is hoping he can solve a family riddle...
We've been all over the world on the celebrity genealogy hunt this series and have encountered both kings and slaves. But Greg Davies's episode proves that the most fascinating stories are often closer to home, especially when it comes to scandal.
The comedian heads to Wales to trace his paternal ancestors and solve a family mystery as he tries to work out the identity of his grandmother Edith's unknown father.
He learns his great-grandfather was quite a character who had a fondness for a drink and more than one lady on the go – in contrast to his deeply religious father!
For us, though, the most compelling moments are Greg's moving reflections on his close relationship with his own late father, Robert.
