I found an old obit of Katie (Katazryna) Brangiel (Brongiel) nee Pyznar. Married to John her son was Walter Siwek married to Lillian with a son Michael. Died in Chicago 12/12/75. Pyznar was also a maiden name of my gr-father's first wife Sophie (Zofia) and was wondering if Katie would have been related to Sophie.

Thanks in advance for any help.
