Stars from the worlds of music, comedy, sport, television and film are set to discover their families' stories as BBC One's hit show Who Do You Think You Are? returns for its 15th series. 

WDYTYA? production company Wall to Wall revealed today that the show's latest celebrity line-up will consist of eight stars: multi-awarding winning actor Olivia Colman, musician, DJ, fashion designer and British icon Boy George, Strictly Come Dancing's head judge Shirley Ballas, comedian and Not Going Out actor Lee Mack, presenter and former JLS member Marvin Humes, barrister and television personality Robert 'Judge' Rinder, Coronation Street and Our Girl star Michelle Keegan and gold medal winning Paralympian Jonnie Peacock.

The series will start with a standalone episode in early June as Michelle Keegan discovers a suffragette ancestor with connections to Emmeline Pankhurst, in an episode aired as part of the BBC's 'Hear Her' season celebrating the 100th anniversary of women winning the right to vote. 

The rest of the series will follow later this summer, starting with Olivia Colman's episode, which airs at 9pm on BBC One on Monday 9 July.

Fatima Salaria, BBC commissioning editor, called the new series "must see TV at its best".

Who Do You Think You Are? won the Best Feature award at the 2017 BAFTA Television Awards.

The latest series will see the celebrities travelling to Genoa, India, Jamaica, South Africa and Latvia, uncovering stories of the First World War frontlines, the East India Company, adultery, asylums and more.

Colette Flight, executive producer for Wall to Wall, said: "Britain's best loved stars are once again delving into their family trees, uncovering hidden secrets and solving mysteries.

"The stories they unearth are revelatory, often unexpectedly humorous but always affecting."

Michelle Keegan

The star of Our Girl, Michelle Keegan goes from onscreen soldier to military historian as she discovers her family's connections to Gibraltar, a fortress during the Second World War. In an episode shown as part of the BBC's Hear Her season marking 100 years since women first gained the vote, the actor also unearths a special connection to Emmeline Pankhurst, leader of the suffragettes.


Olivia Colman

Acclaimed actor Olivia Colman thinks of her family as "fairly boring", and expects to find forebears in England and Ireland - and perhaps France if she's lucky. Instead, while her travels into the past begin in Norfolk, they eventually take her to India to uncover a story involving the East India Company and a brave little girl making a lonely sea journey to England.


Boy George


Boy George

The Culture Club singer and presenter of The Voice will trace his roots to Ireland, uncovering mysteries in his family tree. While his episode is still filming, George recently told ITV's Good Morning that he's hoping to learn more about his "mum's mother" found "wandering the streets" as a child.




Lee Mack

Comedian and star of Not Going Out Lee Mack thinks he inherited his knack for making people laugh from his great grandfather, Billy Mac. A music hall entertainer, Billy honed his craft in one of the toughest imaginable theatres - the Western Front during the First World War, where he served after joining one of the pals' battalions in Liverpool.



Shirley Ballas

The episode starring Strictly Come Dancing's head judge, Shirley Ballas, has still to be completed. But this much we have heard: Shirley heads to South Africa and it's been said she "makes a massive discovery". It's the second year running WDYTYA? has featured a Strictly judge. Last year, Craig Revel Horwood discovered he's descended from a champion clog dancer.



Marvin Humes

Having first found fame as a member of JLS, Marvin Humes has gone on to present This Morning and The Voice. In his episode, Marvin travels to Jamaica to traces his father's family line.




Sir Ian McKellen


Robert 'Judge' Rinder

A barrister who sprang to fame in Judge Rinder and latterly as an exuberant competitor in Strictly, Robert Rinder is a larger-than-life character. But the quieter pleasures of family life lie at the centre of his life. In a heartbreaking episode, he travels to Europe to explore how the Holocaust profoundly shaped his family's history.



Jonnie Peacock

Twice a sprint gold medalist at the Paralympics, in Rio and London, Jonnie Peacock was already an inspirational figure. Then, in 2017, he became the first amputee to appear on Strictly Come Dancing. As to what the Cambridge-born athlete will discover as he researches his family tree, his episode is currently in production.
