When actress Jacqueline Clarke was still a young child, her mother revealed something that was to change her life forever - that she was adopted. It was never spoken about again but, after the death of her adoptive parents, Jacqueline began browsing the family registers for any trace of her birth mother. Drawing a blank, she turned to a professional genealogist for help. Before long the genealogist hit gold, uncovering a sister, Sylvia, who had also been adopted as a young child. After 70 years apart, the sisters are back in touch and are going to visit the house where their mother lived and where they were both born. Sisters Tracy Kerrison and Theresa Horsler had a happy childhood growing up with their parents in Hounslow, London, but they were aware from a young age that they had an older half-sister, Leslie. Tracy and Theresa's dad had been married before and Leslie had been born to this marriage. For several years, the sisters saw each other regularly, with the younger siblings even attending Leslie's wedding, but when Tracy and Theresa's parents moved house the sisters lost touch. Years later, when their dad died, Tracy and Theresa were keen to contact Leslie and, with the help of a family-finding company, they tracked her down and are meeting up for the first time in nearly half a century.
