Seeking info on my great grandfather Walter (Vaslav) Niznik. Here is what I know: He was born about 1880 in the Polish section of Russia. He emigrated to the US sometime before 1908 because he married Aniela Rusak in Pittsburgh, PA in late 1907. She was born in Wilno, Russia and emigrated in 1907. They lived in Bruceton, PA and raised six children - Margaret (Panaride), Mary (Lenger), Sophia (Robbins), Veronica (Karhut), Michael, and Katherine (Karhut). I believe Walter had two brothers who emigrated together in 1907 - Ossip (Joseph?)and Steven. Any help would be most appreciated.
