I would find a library in Rolla or Cando ND. Next, try cities of Devils Lake or Rugby. If you can't go there in person, at a slow time of day call the library. The head librarian might be able to look up county records for Towner County. Depending on settlement of the area, there also might have been an obituary. The librarian should also know about what newspapers were in circulation in that era. I don't remember when the person you seek died - 1910 or was it later. I think that part of ND was settled around 1900.
