I would try contacting the cemetery and see if they can help you.I'm not sure what cemetery this is.
You could also contact the public records office in North Platte (the clerk's offic) and ask them what you can do to get information on her, etc. They should be able to tell you what cemetery Helen is buried in. Here's the main link:
If you click on the link for the Public Library, you could ask them if they have archived newspapers on microfilm.If they do, you could ask if they would look for an obituary for Helen, and what the cost would be, etc.
