I am trying to find out what happened to my grandmother, Anna Cowles Hrudicka, born about 1894. Father was Albert Cowles. Mother was Mary Fuhs. Brother Hal Blake Cowles. She was married to Robert B. Hrudicka and had a son Robert Jr. born about 1917 according to the 1920 Illinois census. Robert Jr. & Hal Blake Cowles were living with Mary Fuhs and her 2nd husband, James Sullivan in the 1930 Illinois census. Somewhere between 1930 and 1940 Robert Jr. changed his name from Robert Hrudicka to Robert Sullivan. Robert B. Hrudicka remarried a Rosella McGartland in 1930. My father, Robert Jr., lost his life in World War II when the USS Spence went down in a typhoon.
