GD,
With just a first name, that is a tough one, do you know where she lived? maybe you could check the real estate records and find out who owned the house, maybe it was her parents, you might get a last name that way.
As far as reporting your abuse and getting any kind of satisfaction from the courts, all i can say is it is a very difficult, long, sometimes very painful, frustratiing process and the end results i dont think ever leave anyone feeling much beyond drained at the best and far worse when things dont go as one would hope. It is a very tough road to go under the very best of circumstances. I suppose the first step would be getting an attorney interested that was willing to help get the details you need and find her....
I hope your getting some therapy for the issues that come out of being abused at that age.
I wish you well, and i am glad you found us. Feel free to come back and keep talking, if anything helps i know keeping the talking going does.
Best of luck to you with all your dealing with,,
John
