Looking for birth Mother or Father

I was born 3/8/79 and my birth name was GORDON i was born in Pittsburgh, PA. My adoptive family will not tell me any information on my birth parents and i would love to meet them and try to reconnect with them as well. The adopted family name is GORTON, im told by my adopted sister that me and my younger brother are blood brothers, our parents names were Debra( not sure if this is how she spells her name) Warner and John Gordon i do geneaology research and have found that my birth father is deceased but mother is suppose to be alive and liveing in Pittsburgh some where. was woundering if someone might be able to help me find her. im married now and my wife and i are wanting to start a family but knowing of family medical history and such, would be nice to know who i came from and what they were like :)
