If a birthmother lost her baby to adoption in Ohio in 1980, what should she do next to find him?

She has registered on ISSR,etc. All details were kept from her and no family left to ask. What about one of those Omni Trace type groups? Shedoesn't want to interrupt a life. Just wants to know "the end of the story" and die peacefully. Thanks for your help. She is a good friend who is quite ill and I know that this will help!
