Solving a Puzzle–Who is M. M. Colbiørnsen?

Sometimes in genealogy we work long and hard to find someone we’re looking for.  These are often called “brick walls”.  People who we just can’t seem to locate.  Other times we have the inverse problem.  Seeing a person and having no idea who they are.  Well, when you find out who they are (or even if you think you have) it’s just as exhilarating as breaking through a brick wall.  I managed to solve just such a puzzle in my own family that dates back to my very beginnings last summer.  My mystery woman was named Mary Colbiørnsen.
