Have you contacted the agency you used? You can leave contact info in the file. If you want me to find her for you I can. Please send me a private messgae with her birth name and anything else you know.
I don't charge a fee.
I contacted the agency a few years back. They told me that when they moved they "misplaced" my file. Then, somehow they contacted the adoptive mom but she said she didn't want to make any contact. My daughter was 21 at the time.
