Looking for birth family dob 8/15/1952

My mother had to give up her daughter up for adoption when she lived in Vermont. My mother would have been around 22, which would make the year abour 1952. She says that she went through a state agency, so I don't know if a doctor was involved. Perhaps we could talk more? There may or may not be a connection. I know who the birth father is, if you are my sibling. Terri
