I wish I could help, but I can eliminate onefor you...
I am guessing your Mary Szymanski was buried in St Adalberts, in April of 1971. (There are 4 other Mary's there)
The Valentine Szymanski buried there on Sept 1942 was the husband of Antonia Herod and Victoria Piekarski -- the rest of his family (my husbands) are all in the Portage County area. He had no children of his own in Milwaukee
I have ALOT of zielinski/zelinski and szymanski/ shemanski /schemanski but none that can be of help to you, yet. I am trying to create a index of both familys so I can keep them straight...I just have names and not alot of info yet on the Milwaukee Zelinski's and Szymanski's. I would LOVE to share info with you. Thanks for posting what you have.
