Bryan-searching for bio-family/mother

I was born in Alburquerque, New Mexico at the Presbyterian Hospital in albuquerque, but my adoption was finalized in Illinois. My date of birth is 9/14/1968. I was adopted 7 days after my birth by the Pratt family. I am an African American Male. My birth mother was very fair skinned, and my birth certificate states caucasian as my ethnicity, so it could be possible that my mother is bi-racial or caucasian. The name on my birthcertificate is Baby Boy Stultz. This is the only information I have.
