Emma Prochaska was born in Butler County, Nebraska. Most likely near Abie, Ne. She was the daughter of Jan (John) and Victoria (Dostal) Prochaska. John was the son of Frank Prochaska and Clara Walla. John was born in austria Hungary-Moravia. Victoria was pregnant when they married. John died about a year after they married and is buried in the cemetary at the Catholic Church in Abie, Nebraska in the Prochaska Family plot. About Five years later(1888), in a civil ceremony, Victroria married Frank Stava. Victoria was the daughter of Joseph Dostal and Anna Cehacek. I think that Frank was also a native of Butler County but had moved to Sheridan County in his mid 20's. At the time of her marriage to Frank she was 22 and he was 30.
I hope this helps. Jane
