Britain’s best-loved family-history series, Who Do You Think You Are?, returns to BBC One this summer to celebrate its 10th birthday and 100th episode.

 
Over the past decade, the hugely popular genealogy show has told the moving and heartfelt stories behind 90 famous faces, tracing their ancestry, discovering family secrets and surprises with tales of poverty and prosperity, love and loss, war, immigration and struggle.
 
This year, the glittering line-up features 10 more well-loved stars: award-winning actress Julie Walters; comedian and actor Billy Connolly; star of British Bake Off Mary Berry; acting legend Brian Blessed; actress Sheridan Smith; comedian/actor and the man behind the hugely successful Mrs Brown’s Boys, Brendan O’Carroll; actress Tamzin Outhwaite; presenter and DJ Reggie Yates; actor Martin Shaw; and model and actress Twiggy. From murder to bankruptcy, ice-cream selling to corset making, revolutionary land wars to syphilis, the new series reveals more extraordinary stories from our celebrities’ families.
 
To mark a decade of Who Do You Think You Are?, a one-hour special will accompany the new series, delving into the treasure trove of extraordinary TV moments that have marked the series. From Jeremy Paxman’s tears and JK Rowling’s joy, to the saints and the villains. From very large books to very white gloves, we remember the highlights and hear from the celebrities themselves about their Who Do You Think You Are? journeys.
 
Leanne Klein, CEO - Wall To Wall Television, says: “For 10 years, Who Do You Think You Are? has shone a light on British and world history through the ancestors of some of our most loved celebrities. The fact that it has inspired so many of us to look into our own family histories too is a sign of its enduring popularity.
