Hi! I was just doing some research on Anna Szumalo and some of the info you have is very close to some of the spellings that I have.
This is what I have:
I think Anna might be my great grandmothers 1/2 sister?? This is pretty cloudy. Here name was Anna Landowski or Liszka (this is close to the spelling you used).
So do you know what Anna's maiden name was. My great grandmother was the Poland- immigrated to Chicago and married a man by the name of Albert Lach.
Can you email me back: firstname.lastname@example.org
