My grandmothers maiden name was Sofia Szcaerba, married to Martin (Max?) Filip, who died, then married to Niemic (don't know first name). They lived in Keisterville, PA, which is a tiny former mining town near Uniontown (southwestern PA). I don't seem to be able to obtain much information from immediate relatives, I realize this is a very long shot. I do know she emigrated from Polish Austria, probably around the late 1890s.
