Patricia Hart grew up in the colliery village of Moorends in South Yorkshire, where her father was a miner. Shortly after being demobbed from the Women's Royal Army Corps, she discovered she was pregnant, and with no support from her boyfriend, made the decision to give up her baby for adoption. Now, after several health scares, she fears time is running out to find her daughter. Army reservist John Farrell, from Bootle in Merseyside, was a teenager when he learnt the man he had called dad all his life was not in fact his father. At the time, anger prevented him from wanting to know more, but now, as a parent himself, his need to know his birth father has grown.
