PREVIEW: Long Lost Family - Born Without Trace, ITV

The BAFTA-nominated programme returns for a third series, as presenters Davina McCall and Nicky Campbell reveal more astonishing stories of foundlings desperate to discover their identities and meet birth family, after a lifetime of not knowing where they came from.

Foundlings are people abandoned as babies, often in the first hours and days of their lives. Born without trace, with no birth record or name, until now they have been unable to solve the ultimate mystery of their lives – who they are.

Over the last four years, the team behind Long Lost Family has combined cutting-edge genetic genealogy with DNA testing technology to try to help more than 30 foundlings unlock the secrets of their past.

The stories in this brand new series span five decades: from a woman left over 70 years ago on a luggage rack of a train in Paddington station, to a young man left in toilets near a football stadium in Wolverhampton as recently as 1989.

Episode one features two foundlings abandoned in Chesterfield just over 18 months apart in the 1980s, Helen Knox and Victoria Vardy.

Long Lost Family airs Monday 24th-Wendesday 26th May at 9pm on ITV.
