the Vienna cemeteries search page https://www.wien.gv.at/grabauskunft/internet/suche.aspx
shows several Krumpholz buried at the Stammersdorf-Zentral location (cemetery=Friedhof), at least one of them is on your list.
If you want to have a look, just enter Krumpholz under 'Familienname' and select Stammersdorf-Zentral from the list of cemeteries.
You might btw also look at the Krumpholz entries in the Austrian phone directory at www.herold.at
If you select the English language option and PeoplePages, just enter Krumpholz as the Name and 1210 for the Zip code (=21st district, where Stammersdorf today lies). Or select Lower Austria as the Region. People with an address in Groß-Enzersdorf, Langenzersdorf, Hochwolkersdorf and (not exactly, but possibly also) Leopoldsdorf are quite close to the area.
