Pesia Kaganskaya and Omo Kaganski

This is a picture of my paternal grandmother, Pesia Kaganskaya, and her younger son, Omo Kaganski. The photo was taken in Radomyshl in the 1920s. My paternal grandfather, Meyer Kaganski, born in the 1870s, worked for his older brother, Moshe, who was a leather specialist and became rich during the Civil War. During the Civil War a gang of a White Guards officer came into Radomyshl. My grandfather Meyer, a handsome tall man with a big dark beard, was the first they met on their way. The bandits brutally murdered him. My grandmother Pesia had to raise her three children on her own: her daughter, Malka, my father, Yakov, and her younger son, Omo. This incident happened in 1918 or 1919. I know little about Grandmother Pesia. I know that after her husband perished she tried to move to America with her younger son, Omo, but he didn't receive a medical certificate due to some health problems and they stayed in Radomyshl. I saw her once in 1940 when she visited my mother. My grandmother was very religious. She wore a kerchief, celebrated all Jewish holidays and Sabbath, observed Jewish traditions and followed the kashrut. She died after the war, sometime in 1946. My father's younger brother, Omo, lived in Moscow. He was a cab driver. He had a Russian wife. He died in 1955. That's all I know about him. We were not in contact.
