Born 10/19/1955

I would like to find my birth brother or half brothers/sisters. My last name at birth was "Gerace". I know that I was born at McAlpine Hospital on Broadway in Providence. My birth mother's name at another point in her life was Mary Maurice. I have a half sister who got married years ago to a "John Medeiros". I also know I have a full brother "Gregory" who is 10 months younger than me (born 1956) who was also given up for adoption. I know I have a few older siblings probably in the Providence area. Any information would be helpful in contacting them. My adoption was what they called a "direct adoption". Someone in my family who is now deceased knew my birth mother, but my adoptive mother would not tell me any details because of insecurities.
