Waterville Maine

I am a 26 year old male born and adopted in Waterville Maine on June 12th 1982 in one of the hospitals in Waterville. I was sent to Michigan with my adoptive parents. My bio father was in his late 50's or early 60's at the time. He had many daughters that are much older than me, one may even be in her 60's. I was told that there was a divorce going on at he time of my birth and keeping me was not an option. My bio mother was much younger than my bio father and I was told that I had 6 sisters and possible more half siblings. My Bio mother may have named me Joshua. I may be of Italian decent. Any info would be great:):thanks:
