ISO any birthfamily member - 7/31/69 Miami

I was born 7/31/69 in Miami. Do not know the hospital-- I have one of those weird blue birth certificates that lists on the certificate number, not the hospital code. Bmom signed consent for adoption 8/6/69, same day I was placed with my adoptive parents. Adoption handled through Helen Tanos Hope and finalized in Juarez, Mexico on 11/23/71. Was told Bmom was 21 at the time of birth and a native of Illinois. Would love to find any member of my birthfamily.
