Want to find my cousin

Hi. I am looking for my cousin. I am almost certain that my cousin is a she. I found out on Mother's day of 2003 that my aunt had to give her child up for adoption in 1981. I was born in February of 1981 and from what my mother has told me, which has not been too much, my cousin was born shortly after, like no more than a couple of months I assume. My aunt was moved to Erie, Pa by my grandparents so that the birth was not known. Ya, it was and still is a family secret my aunt was pregnant. I understand why it was done although I don't know that many people would understand and accept the circumstances of the situation. Anyways, what I learned over a year and a half ago explains so much about my aunt and my grandparents. By the way, no one, including my aunt knows that I know about this. My mother let it slip which I sometimes think that she didn't realize she was telling me but a part of her wanted to tell someone who didn't know in order to get it off of her chest so to speak. If someone can help me to find my cousin, born between February and say April of 1981 in Erie,Pa but whose birth mother was from West Virginia and the mother was 19 years old at the time, please contact me. I know the information I have provided is very wide and can really relate to so many people, but it is worth a try.
