I'm hoping to find the names of the parents of an Adolf Grossbard, who married in Vienna in 1917 to Fanny Kupferstein-Binder.  I'm particularly interested in his place of birth and his mother's maiden name.  1917 is too recent for Ancestry to have the Viennese marriage record scanned, and it was a military service so maybe not easily found, anyway.  Adolf died in 1935 and is buried in Zentralfriedhof, under the misspelling "Grossbart", in the same grave with a Sarah Grossbard and close to a Solomon Grossbard (their ages suggest they could be his parents). Adolf's death in 1935 was also too recent to be online.  If this Sarah is his mother, it's possible her maiden name was Laufer or Sperber. Any suggestions how to find more? 

Thank you,
