If I was born in the State of GA and adopted through the state of PA at a couple weeks old which state holds my birth certificate and what parent names do I use?

In this situation, the state where you were born (Georgia) has both the original birth certificate, and the amended birth certificate. The original birth certificate lists your birth parents, but it is sealed, which means you cannot get it. The amended birth certificate with your adoptive parents names is your legal birth certificate, and the only one the state will release.
