Do you know her family's religion and where she died (was it at or near Bowman, ND?). These ND towns are so small you might contact a Catholic or Lutheran (whatever the faith) church in Bowman ND. If they don't have records, at the very least they should be able to direct you to the county library (is it in the city of Bowman?) and there you should be able to find her obituary. The obit usually listed cemetery or city where interred. If you are not living in ND you might ask the librarian for help. Bowman is a very small town, probably under 700 people. All it took was 15 minutes in a library to locate ancestral graves for my friend who lives in Georgia. She had only the year died and names of her ancestors and the cities where they lived.
