Maoist 'slave' thought to be the daughter of a member who died in mysterious circumstances Having moved to London in the early 1970s to study, she and her boyfriend were recruited to the Workers Institute of Marxism Leninism Mao Zedong Thought. Eventually her boyfriend's family became so concerned for his welfare that they virtually kidnapped him for his own safety, according to relatives of Miss Davies. It is not clear whether he was the father of Miss Davies" daughter, but when she died in 1997, the collective effectively adopted her daughter who was 14 at the time. Miss Davies died seven months after falling out of a bathroom window at a house in Shakespeare Road in Herne Hill. Last night Miss Davies" cousin Eleri Morgan said she and her brother would be willing to take a DNA test to prove that Rosie or Prem as she was known by her mother, is their relative. The property in Herne Hill where Sian Davies fell out of a bathroom window, dying seven months later from her injuries (JACK TAYLOR/NATIONAL PICTURES) Miss Morgan, a retired teacher who lives in south London, told ITV news: "From looking at the papers today and looking at photos I have of Sian when she was younger, no one can dispute there is a likeness there." She added: "We'd always wondered if Sian had any children and I know her mother was always wondering if she had grandchildren. So it's such a shame, if this turns out to be Sian's daughter, that they didn't have the compassion to let her know. We'll have to wait and see. Miss Morgan added: "When Sian was lying in King's hospital for seven months, I believe they did know where I lived, which was down the road from King's. I could have seen her. Her mother could have had the chance to have said her goodbyes to her. That is unforgivable. She went on: "I have no problem about meeting her at all because she could be part of the family. I'd be very happy to do that and so would my brother, be very happy to see her. Hopefully some of the women in the house may well have been the ones who were there when Sian was with them all those years ago. I certainly feel there is far more information that needs to be found about her death.
