info about my adoption??

Hi All... I am an adoptee, born may 19 1980. I was in foster care in the bethel park south hills area until december of 1980. I was told that my birth mother was around 38 in 1980, birthfather was older and was previously married. I am aware that i may have older siblings, one of which has downes syndrome. He would be approxamately 2 years older than me. I was born in West penn hospital. If anyone has any info or insights to anything i've posted please let me know. I'm new at this whole thing so please bare with me.... babyblupea1980
