I am looking for any information about my grandparents Morton and Helen Rathburn of Melrose (Boston), Mass. Specifically, I am trying to locate the cemetery where their gravesites are located. My father, Marty Rathburn (their only child), passed away in 2003. Now I do not know where to locate their gravesite as he was my only source for this information. I only know that it may be somewhere in the Cape Cod area. All my research has dead-ended. Any information is appreciated.
