"Anton Vielgut, b 1895 in Kraebach Austria, emigrated to Milwaukee after WWI. Son of Lorenz Vielgut & Margaret Bitner. Looking for info on Vielgut and Bitner families in Austria. Also, Ludmilla Madrutter, b 1905 in Gratz, Austria. Daughter of Ludwig Madrutter and Marie Fritz. Emigrated to Wisconsin shortly after WWI. Looking for info on Madrutter and Fritz families."
Have you collected the family death notices published in the German papers for a Lorenz Vielgut and Margaret Vielgut? or for a Jacob and a Mary Vielgut? They're indexed in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950). Surnames referenced in the index with Vielgut are Madritsch and Pinter (possibly sh/b Bitner?).
There were also notices in these papers for Ludwig Madrutter. There are about 100 entries for the surname Fritz.
