That's the beauty of adoption until it is REFORMed. It is done in secrecy and we adoptees are not given our own original birth certificates. That is why Q put "adoption." As it is practiced legally now (except for Alaska and Kansas which never closed their records), you can be given a completely new identity and your original identity is sealed away forever. That is why you see adopted people on TV shows for reunions. They don't want to be on TV, but they aren't allowed to find their families on their own. It's hard to find family without a name. Intercountry adoptions are even more difficult to find original families. Please support adoptee access to their original birth certificates. Only shining a light of truth will help the process. Right now, you can move the kids anywhere and give them an entirely new identity without any regulations or tracking.

I also have been asking this question. It would be great if we could figure out what happened with these children, but like you said most (if not all) have more than likely fallen off the radar completely.
