Coy,
I haven't read all of your posts. But I just wanted to make a quick reply. If that is ok.
Please register with as many registries on the internet that you can find. THE FREE ONES!
Register with International Search and Support. Adoption.com.
PR adoptee search and support sites, etc. You can try: yahoogroups, googlegroups, etc. Put: Puerto Rican Adoptee in your browser, and see what comes up. Or join a search group called: Soaring Angels.
They are very helpful and supportive.
See if you can get any non-id information.
If an adoption agency was used or foster care agency.
Put your date of birth in your google browser and see what comes up.
That's a start.
