Marvin Humes’ Who Do You Think You Are? episode moves viewers with its revelation about his family’s history of slavery

Who Do You Think You Are? often astonishes celebrities with its revelations about their family history – and the latest episode with Marvin Humes was no exception.

The former JLS band member turned TV and radio presenter discovered on Monday night’s show that one of his relatives was a black slaveowner.

• The best TV shows to watch on Netflix
• Everyone is now even more in love with Olivia Colman after her Who Do You Think You Are? episode

As the BBC1 programme helped Humes trace his roots in England and Jamaica, he learned that his four-times great-grandfather owned two slaves, despite his own parents having once been slaves themselves.

The revelation, and Humes’ reaction to the news, moved viewers who took to Twitter to praise the show.

Ahh imagine finding out your black ancestor was a slave master.. #WhoDoYouThinkYouAre

Sometimes family history can be difficult and unexpected hearing. Always be prepared to learn something you would rather not know #WDYTYA

Loving this #WhoDoYouThinkYouAre. Marvin is fantastic – bright, thoughtful, warm, assimilating the unexpected, like a black ancestor owning slaves, and absorbing the history. Absolutely fascinating. #WDYTYA

Humes was “shocked” to discover his ancestor was a slaveowner as he didn’t know that black people owned slaves. He recently told TV Times: “I’m not angry, I’d like to think that being a black man himself, knowing what was going on, he’d have treated them with respect.”

Beyoncé has also recently revealed in a new interview with Vogue that she is descended from a slaveowner. “I researched my ancestry recently and learned that I come from a slaveowner who fell in love with and married a slave,” she said.

Who Do You Think You Are? continues on Monday 13th August, when TV judge Robert Rinder will be tracing his family history.
