The death certificate should give you the burial place. It can be ordered from the Municipal Archives or Family Search (free). https://familysearch.org/learn/wiki/en/Photoduplication_Serv...
Death indexes at IGG only go through 1948 so, if Elizabeth died after that, her death is not indexed above. However, since George died before 1940, you might try one of these for him; it's likely they are buried together and a call to the cemetery can give you more information on Elizabeth as well. Or you might just want to take a chance and order certificates for both.
I believe another poster suggested the website Fulton History for an obit although it does not have all newspapers for all areas.http://www.fultonhistory.com/Fulton.html
Hope this helps.
