||I am looking for my half sister. I don't know her name, dob or pob. She would have been born in 1969 - 1970. Her mother and the person she knows/knew as her father were married in Leytonstone approx 1969. Her Mum and my Dad had an affair before the marriage. They both worked for Buck and Hickman in the East end of London. Her non biological dad knew she wasn't his but I don't know if she was ever told. The family name is something like buckwell or blackwel. I am Kevin Brennans daughter and really want to find my half sister.
