boy born 2/12/71 in Philadelphia Area looking for birth parents

HI everyone! I am new to this site, but I am REALLY hoping to find my birth parents someday. Here is the information I have about myself and my adoption: Born 2/12/71. Birth certificate says place of birth is montgomery county, Borough of Norristown. Taken to St. Vincents Hospital after my birth. Placed with Catholics Children's Bureau, Inc. at 49th Street & Wyalusing Ave, Phila. PA for adoption. Adopted by John and Helen Morris of Havertown , PA. Both adoptive parents are now deceased and looking for my birth parents. I was told that my mother may have been 18 years old when she gave birth and from Florida....not sure how accurate this is. Thanks ahead of time for any information anymore may have. If you know of any good agencies to contact to help me I would appreciate that information also!
