I just read your post from 2006. I saw that your Josef had a sister, Rose (Rosalia). The first names of my grandmother Rose's children included Anna and Joseph. I have my grandmother's baptismal certificate, and it names Nicholas and Agatha as her parents. Could be that Michael is actually Nicholas. Do you have any idea where Josef lived in Chicago? If it is the McKinley Park area, then most likely your Josef is my grandmother's Rose's brother. According to what I know, Rose came from Cracow/Tarnow area in Poland. I have very little info because Rose died in 1959 when I was very young.
