I wonder how you know your father died of typhoid fever in Voronezh? I ask=
because my great-uncle died there as well, also in January 1943. I learne=
d >from Yad Vashem that there was a major battle on the Don River near Voron=
ezh in January 1943, and many Jews in the Labor Service died there. Some ar=
e buried in the local cemetery. My great-uncle was not.
