You need to search for the birth record of Maria Feiler or Feiller in the church records for Poppendorf and nearby areas. On cursory glance, I cannot find a Maria Feiler born in and around years 1887/88 either in the r.c. parish records of Heiligenkreuz (which was the parish for Poppendorf) or Königsdorf which was the r.c. parish for Eltendorf and Zahling (Körtvelyes). Could Maria have been born into a Lutheran family? If so, please check the related birth records of Eltendorf which served Lutherans in Poppendorf as well.

Kreinecker does not sound like a name present in and around Poppendorf. I recommend that you consider checking the residency records (Meldezettel) of Vienna. The residency records of the early 20th century most of the time contain the birth date and place of the person. Check also for the name Matzka. Even if Lorenz was born in Vienna, his parents may have moved there from their home town.
