Who’s on Who Do You Think You Are? tonight?
Tonight (30 ) features actor Ralf Little.
Death in Paradise star Ralf Little leaves the sun-drenched Caribbean well behind as he heads to the Orkney Islands off the north coast of Scotland to investigate his grandfather Arthur’s experiences during the Second World War.
Ralf is astonished to discover that Arthur was caught up in one of the most important battles of the conflict.
Looking into another branch of his family, Ralf is thrilled to confirm a family rumour that he has a Welsh international footballer on his family tree.
Once a serious footballer himself, Ralf’s joy turns to despair when he learns that his great-grandfather’s devotion to the beautiful game was severely tested by a wave of religious fervour that swept through Wales in the early 1900s.
Finally, on returning to his hometown of Manchester, Ralf is delighted to learn that another ancestor played a key role in the development of this great industrial city.
The episode airs on Thursday, 30 June at 9PM on BBC One.
It’s a brand new episode from series 19.
Also taking part in the new series are Sue Perkins, Richard Osman, Matt Lucas and Anna Maxwell Martin.
