still searching for bmom in columbia S.C.

anyone have any ideas about getting non-id. I was a private adoption in columbia S.C. and I tried to get info from the SCDSS. they were of no help. I'm pretty much stuck. I don't know where to look and it's tough because I live in N.Y. Anyone with any ideas please respond to this message. I was born baby girl Lee in columbia hospital on 2/28/68.
