Source: Cleveland Press; Cleveland Necrology File, Reel #112.
Notes: Gliwa, Stanley, residence, 3875 W. 18 St., dear brother of Jan in Poland, beloved uncle of Andrew and Walter. Services Monday, Aug. 8, at 9 a. m., at St. Barbara's Church. Friends may call at A. J. Tomon & Sons Brooklyn Funeral Home, 4772 Pearl Rd.

If Stanley is the uncle of Walter then it is very likely that his brother Jan is Walter's father. And why no mention of Walter's sister, Victoria?
