Searching for Birthmother/father or siblings

Hello, I am currently in the search for my birth family. I was born on November 18, 1966 in Cornerbrook, Newfoundland. I was told by my adoptive mother that I was removed from my mothers care and placed in the foster system. I was adopted some time later, probably thru a Catholic organization. I do not know my last name, but my first may have been Jeffrey, or Barret or a combination of the two. Thanks, Neil
