Searching for foster parents

This is prob a strange request and it will prob lead nowhere since it’s been so long but I’m going to try. In the late 1960s, prob somewhere around 1967, my brother and I were put into the foster care system. Our mother was pregnant and the baby was put into care at birth.We were all separated but my parents fought hard and were able to get us back, so a happy ending.But here’s our request, we would like to know how our foster families are.My brother has the biggest request.The foster care system actually adopted my brother out to a family who had 2 or 3 daughters but wanted a son. I’m not sure what happened, how they were able to adopt him out and then my parents were able to get the adoption overturned. My sister was taken into care at birth and her foster parents stayed in touch with my parents until we moved out of Ohio.I don’t remember much except the room I slept in had several small beds and I do remember 3 or 3 kids and an older boy. I also remember celebrating my bday with them.We were living in Columbus so I believe that’s where they were located. Can anyone help?
