I just got a copy of a social security application for my great-grandfather: JOHN FRANK NATH, born 11/21/1884 in "Austria- Hungary" - but,of course, that could be just about anywhere in eastern Europe. His parents are listed as JOSEPH NATH and Elizabeth Mueller. I know JOHN FRANK NATH came over as a child,in about 1892,I assume with JOSEPH NATH and Elizabeth. I am not aware at the moment of an ANNA NATH, but I have not yet looked into these persons' siblings. These NATH's lived in the Mt. Oliver section of Pittsburgh, referred to in the census as Lower St. Clair Township.
