The genealogy show’s latest stars include Claire Foy, Lesley Manville and Bear Grylls. 

After a truncated 5-part 19th series last year, Who Do You Think You Are? returns for a more substantial 20th series this June.

The celebrity genealogy is back to lift the lid on the family history of nine celebrities from film, television and the stage.

This year, the show’s line-up features the composer Sir Andrew Lloyd Webber, actors Claire Foy and Lesley Manville, and former Strictly Come Dancing professional Kevin Clifton.

Also appearing are comic Chris Ramsey, actor and comedian Emily Atack and adventurer Bear Grylls. Broadcaster & DJ Dev Griffin and television medics Chris & Xand van Tulleken round out the list.

The series promises shocking truths, tears, and tragedies as well as moving and uplifting stories, as the celebrities uncover affecting moments in their family histories that will impact them in ways they didn’t think possible.

With familial discoveries that range from clog-wearing rope dancers and Scottish royalty to murder trials and tragic accidents, the celebrities’ journeys take them across the UK as well as to Ireland, the Netherlands, Canada, Jamaica and Australia in pursuit of the truth behind their family stories.

Simon Young, BBC Head of History, says:

“As one of Britain’s most beloved documentary series returns for series 20, the line-up of household names, and the array of astonishing family histories, grow from strength to strength. This series is often imitated but never bettered, and this latest edition demonstrates why.”

Who Do You Think You Are? returns in June.

Series 14 – 19 remain available to stream on BBC iPlayer. They include episodes featuring Charles Dance, Olivia Colman, Daniel Ratcliffe, Matt Lucas and Anna Maxwell Martin.
