Years ago I joined a forum a lot like this one for adoption related issues. It helped me to understand things so much better. I gave up a son at a young age not because I didn't want him, but because I wasn't able to take care of him. I hope some day that he will find me. I'll never be his mother, I hope he has a great one, but it would be nice to know him. He should at least have medical info. Hopefully he will find me someday. I won't look for him because I don't feel that's my right. I sealed the adoption records at the beginning for his sake. We have a Florida Adoption Reunion Registry (FARR), 1-850-922-6234, 1317 Winewood Blvd., Bldg A Room 102, Tallahassee, FL 32399-0700. This might not help, but I do hope you do find your sister and can at least fill that gap. You may want to consider a private detective. A third party is usually advised for both your sake and the other party's. Good Luck Hon.
