Adoptee: 10/26/1974 Springfield Ohio

Hello, My name is Paula and I was adopted out in Springfield Ohio at birth. I am searching for my birth family. I have registered with the "official" Ohio registry and have received my non-identifying information. I have read only 10% of the Ohio birth index is available for searching. Is there anyone willing to search my date for me? I have additional biological siblings, can their years of birth be cross referenced for matches? Has anyone had any luck with this year in Ohio? Thanks so much for reading! Paula
