Looking for brother born march 17 1966

I am looking for my brother, Born march 17,1966 at Redington Fairview Hospital in Skowhegan, Maine. I know that he was born with a full head of Black hair. could be black or brown today. Our mother left him at the hospital after birth. not sure if he was adopted through local agency or not. I know that she had named him Troy allen Jones. while she was carrying him and my grandmother always refered to him as Troy. I would like to find Him. Help would be so appreicated. I am his sister. He has another brother and one more that was adopted by uncle thanks
