I have a Mary Nilan in my family history. She was a witness to my great grandparents' marriage. My great grandparents were Daniel David Cadogan and Mary Jane Morse. They were married St. Stephen, Boston MA 1891. The other witness to the marriage was John P. Quigley. My great grandparents first child was born the following year (Daniel) and his godparents were John P. Quigley and Mary Sullivan. Since it is traditional for the bestman and maid of honor to be godparents to the first child I wonder if Mary Nilan's married name was Sullivan. At this point I know of no connection to my family and Mary Nilan, however if anyone does know of a connection I would very much like to hear fromthem.
