Seymour Knox and Frank Goodyear Mausoleums.
Knox's daughter, Virginia, married Goodyear's son, Frank, Jr. in 1915, the year that Knox died and Goodyear's wife died. Knox's wife, Grace, would build a house at 806 (now 800) Delaware, four doors from the Goodyear house at the corner of Delaware and Summer (now the Red Cross parking lot).
