If you go online to "Find a Grave" type in "Walworth County Cemetery" you can see the marker at the cemetery near Elkhorn. Most of the burials are also recored on this site.
Ed Nace was born in 1831 and died Nov. 01, 1915. He is buried in the Walworth Co. Cemetery. If you can not get the pictures of the cemetery, I will send them to you.
