Researching Anna Tauchert b:9141885 in Frankfort,Germany d:5/10/1921. She married John Valerian Borck(Borucki) b:10/14/1874 Graudenz, Germany d: 5/14/1940 in Illinois. I know they lived in Illinois but have no time frame for coming to the U.S. I am at a dead end for Anna's information regarding ancestors or siblings. Any information would be appreciated.
