ISO Birth mom, Born 2/20/80, West Penn Hospital, Pittsburgh, PA. Birth Name: Mamula

I was born on Feburary 20, 1980 in West Penn Hospital in Pittsburgh, PA. I was adopted out of Butler County, through Butler Catholic Charities. I am looking to find my birth mom and from there, meet any siblings and my birth father. My mom was 19 years old when she gave birth to me and my father was 17. My adoptive parents were told that she did not tell the father of her baby that she was expecting. I also know that my name given at birth was Nicole Mamula. My maternal grandfather had an influential position in the Pittsburgh area at the time I was born. Any help in my search that anyone can offer would be greatly appreciated!! Thanks a million!!
