Long Lost Family: Born Without Trace

ITV, Tuesday, 9pm

Over the past four years, the team has used detective work to try to help 30 people abandoned as babies learn about their pasts.

However, sometimes their discoveries have only been the start of the story.

Here, Davina Mccall and Nicky Campbell update us on foundlings David Mcbride and Helen Ward, who were left as newborns on either side of the Irish border six years apart.

David and Helen learn how they were born out of a forbidden relationship, and look into the possibility that their parents may have been forced to leave another child.
