The obelisk with a cross is peculiar to Catholic cemeteries; it is almost never found in Protestant cemeteries. Here is a typical example from St. Michael’s Cemetery, the vertiginous burying-ground of a German Catholic parish on the South Side Slopes. As with many of the older monuments here, the inscriptions are in German.
It appears that the family lost touch with this monument at some time between 1944 and, perhaps, 1960 or so; the death date of Anton Imling, born 1868, was never filled in.
