I am searching for the burial place of both Minnie Sherer Marders and her husband, Cay Nelson Marders. Both died in Marysville, so I'm assuming they are buried in a local cemetery there.

Minnie Sherer Marders: 1868- Nov. 25, 1940
Cay Nelson Marders: 1858- Mar. 29, 1935

Thank you for any help you can give me!
