Raford Olson is buriied at Marble Lutheran Church Cemetery, as found on Find a Grave website. I do not see Lizzie listed, but Find a Grave does not maintain complete lists of burials. You could write to Marble Lutheran Church to ask about Lizzie. Marble Lutheran Church is in Hendricks, Lincoln, Minnesota.
There may be a local paper for Hendricks, Minnesota, that might have an obituary for Raford. Now that you know his death date, that becomes easier to obtain.
