In my childhood and teen years, I was unaware of any adult trans women in the countries I was living in, and as a young adult, the first local trans woman that I read about was working in sheltered employment for people regarded as mentally deficient. I can't say that I was inspired by anyone local to me but I did occasionally venture out in women's clothes.
When I was about 13, though, I read a lurid article about the British trans woman April Ashley. That was my introduction to the idea that it might be possible to transition from male to female. The article suggested that she was not having a successful time of being recognised as female, though. She would have to be my first role model, although I don't approve of her outing Amanda Lear in later life.
Later I eagerly read about "Tula" Cossey, already mentioned by Dawn. She was the first trans person that I read about who seemed to be having a successful life. I think that I still have my first magazine cutting about her, somewhere.
