I am trying to find out what happened to my great-grandmother's brother, Anton Prause, primarily: where, when and how did he die? What became of his two children?
Anton Prause and my ancestors lived in the town of Mitteldorf which is just north of what is now called Rokytnice v Orlických horách. Mitteldorf is now called Prostredni Rokytnice. The Prauses had a grain mill there.
Anton was born 25 January 1874 to Catholic master-miller Franz Prause and Theresia Rucker. Anton himself became a master-miller and I am pretty sure served in the Austrian-Hungarian army for a while. He married Anna Diwischek on 8 Oct 1901. Together they had two children: Anton Eduard Prause (b. 9 March 1904) and Anna Elisabeth Prause (b. 17 November 1905). Anton's wife Anna died on 31 March 1906, only 23 years old, from tuberculosis. On 22 October 1909, Anton arrived in New York, having emigrated from Mitteldorf, Austria-Hungary. He went to live with his sister Anna (Prause) Christen and her husband Rudolf at their farm in Nebraska. Anton's children did not come with, as far as I can tell. After a while at his sister's farm he returned to Europe, presumably to Mitteldorf. I think he returned before World War I. I don't know what happened to him since then, other than he might have been alive after World War II. Family lore is that my great-grandmother (his sister) sent care packages to him following the war. A cousin's uncertain recollection was that he was in a concentration camp of some sort. I also do not know what became of his two children, whether they grew up and had families. It's entirely possible that Anton & family were nowhere near Mitteldorf during either world wars.
Any information or ideas where to look for the fate of Anton and his two children would be most appreciated.
