Thomas was left as a baby in the waiting room of Reading train station in 1965. Extraordinarily, the first birth relative the team finds for him is another foundling: Martina - left as a baby on the steps of a Dublin church. Apart from DNA, all they share at first are questions – however, their meeting soon leads to life-changing discoveries for them both.

‘Euston Baby’ Rachel’s adoptive mother always told her ‘you were like Paddington Bear, you were found at a train station’, but the parallels end there as Rachel still bears physical scars from her time left alone in a battered carry cot in Euston Station’s long-stay car park more than 50 years later. For most foundlings, the time and place they were left is all they know about their beginnings. Foundling Steve doesn’t even know this – taken into care from an unlicensed foster home, he doesn’t exist in any records before he was nine months old.

We find out what happened next to two foundlings - Harvey and Caroline - who forged new and enduring relationships after their stories were told.
