TV presenters Kate Garraway and Alison Hammond embark on a road trip to find out about their family history using a mix of DNA and genealogy, and by meeting living family members they never knew existed. Kate is excited as she is heading to London to meet her cousins for the first time. For Alison, visiting Jamaica - the homeland of her recently deceased mum, is an incredibly emotional and moving journey, one that brings her closer to her mum as she finds out the most jaw-dropping of maternal histories.

Old friends and now hugely successful comedians, Joel Dommett and Tom Allen are delving into their family history, as they embark on a road-trip around the UK. Through detailed genealogy and cutting-edge DNA, they'll learn of jaw dropping long lost cousins and heroic family histories.  

From London to Edinburgh to Ireland, this trip reveals what makes the pair the way they are. Joel has always felt rootless and is desperate to belong somewhere, whilst after losing his beloved father, Tom hopes learning about his past will cement his dad's presence. This duo's journey is full of emotion, a deep genuine friendship and of course, many laughs.  

Joel learns of an ancestor who not once, but twice, produced inventions that saved thousands, if not tens of thousands of lives – and it could be said helped end the First World War. Heading north, rootless Joel discovers where his DNA says he truly belongs, and it's a big surprise.

Plummy Tom has always felt like a fish out of water in his south London family – but an Irish ancestor reveals it may be his DNA is to blame. He discovers the emotional story of his great grandparents, from a criminal past to a successful career on the stage and the tragic turn that meant they had to give up their baby girl, Tom's beloved grandmother, for adoption. And everyone gets the shock of their lives when it's revealed Tom is related to true TV Royalty.   

Gavin and Stacey favourites, actors Larry Lamb and Alison Steadman, embark on a road trip to find out their family history using a mix of DNA and genealogy, meeting living family members they never knew existed, along the way.

One of the most emotional DNA Journeys yet filmed, Alison comes to learn, through production and subsequent filming that her father George Percy was adopted. Neither her nor the family had any idea. Propelled to know as much as she can and supported by her great friend, Larry they go on a journey that takes them to the Isle of Man, as Alison gets to know the story behind the Granny she never knew.

For Larry, a series of delightful coincidence occur. There's the entertaining bombshell that he's related to one of the world's first famous movie stars, a Canadian actress called Florence Lawrence. A pure coincidence, but Canada is the place where Larry started his acting career himself. He also finds out where his Jewish roots come from, all the way from Lithuania  which just happens to be where his best mate hails from. Larry is blown away by the strange and wonderful connections.
