Not sure about a database per se. Paper records go back years and years and I can't imagine a state or a county or a township paying someone to create a database and input all those records. Alabama, Alaska, Hawai’i, Kansas, Oregon, Maine, New Hampshire, and Rhode Island are the only U.S. states where adult adoptees have unrestricted access to their own original birth records. Otherwise you need a court order and a darned compelling reason.
