Could this John Urzendowski have been the son of Andrew and Ann (Ryba) Urzendowski of Chicago with sisters Aniela, Mary, and Antonette and brothers Albert, Frank, John, Mike, Paul, and Tom? Their birth dates would have been in the late 1880's and early 1890's. My wife is the granddaughter of Aniela.
