My family is from Walter, Russia. My grandfather Johannes Klippert b:1889 left Walter with my grandmother and 2 sons in 1912. He left behind 2 sisters at the time Magdalena b:1895 and Elizabeth b:1891. In the 1970's the red cross sent my uncle a letter which I have never seen that said one of them had died in Siberia. My question: are they any lists that I can look at or resources to seach for this information?? Thank you in advance, Mary B.
