Where are Will and Erik's headstones, and what information is on them?

Will is buried at Fairview Memorial Park, and Erik has a headstone there. On Will's headstone, it says, "William Patrick Sullivan: 1938-2017. Husband, Father, Friend (163)." Erik's headstone is next to his father's. It has his name on it "Erik Ernest Sullivan" (164). Tova's maiden name, Lindgren is supposed to be Erik's second name, but it was not recorded correctly. There is a third stone, which is blank, for Tova.
