Long Lost Family: Born Without Trace returns to ITV tonight, with hosts Davina McCall and Nicky Campbell back for a fifth series.
The emotional programme follows people who were abandoned as babies, often in the first days and weeks of their lives, who until now have had no way of uncovering their own identities.
The team behind Long Lost Family has combined genetic genealogy with DNA technology to try to help more than thirty people unlock the secrets of their past. All are searching for answers to the most fundamental questions: when’s my birthday; where do I come from; who are my parents and who am I?
