Looking for brother born 10/16/76 in St. Louis, MO

I am searching for my step-brother. My (step) dad really wants to find him. His birth name was Bryan James Froelich. Bryan was born 10-16-1976 at St. Mary's Hospital in St. Louis, MO. He was immediatly geiven up for adoption after birth. He went to Catholic Charities in St. Louis, Mo. According to my dad he was still there when he was 18 months old because my dad went back to see him, without sucess. However one of the nuns gave them a picture of Bryan. My dads name is Steven Micheal Scanlon (dob 3-20-58). Bryan's mothers name is Laurie Ann Freolich (dob 2-29-58). That is all the information i know. if you know any information or you know how i can get more information please email me. gavins_mom2003@hotmail.com I have tried search angels but i cannot find any in missouri and i would like to find some one that knows about how catholic charities adoptions work. Any help will be greatly apreciated. Thank you everyone. Staci thompson
