My mother was adopted out of Childrens Home Society Oakland, CA in 1947. We have not had success, however, we have her non identifying information. My mom was told that there was some sort of fire where records were stored. (?) I'm not sure how accurate that is. The non ID information is so detailed and lengthy, you can almost imagine what the names would be! We were told to file through the courts to see if records can be opened. We have not found the time to do this...yet. But we planned to within the next year. If we have any success, I will let you know.
Good luck in your search! Lea
