Season 23, episode 5 of Who Do You Think You Are? UK puts the spotlight on actor Toby Jones as he digs into his family background. The episode centers on two strands of his ancestry, combining a look at his mother’s remarkable acting lineage with questions about stories passed down from his father’s side.

A major part of the program follows Jones as he explores what is described as an extraordinary acting dynasty in his maternal family. That angle gives the episode a strong theatrical and cultural thread, as the series examines how performance and family history may be closely connected across generations.

The episode also turns to a possible link to India, something Jones wants to verify after hearing family stories from his father. The search is framed around whether that connection is rooted in fact or has grown through family lore over time, giving the investigation a personal and historical dimension.

As with the wider series, this installment blends celebrity biography with ancestry research, using Toby Jones’ family story to uncover deeper context behind the names and tales he has inherited. The result is an episode built around heritage, identity and the question of how much truth lies inside long-held family memories.
