Thank you for responding once again. I have both Emergency Passports for John Slezak and one for John and Helen. I also have one manifest with an arrival date of 11 Dec 1919.
I have their burials and their cemetery plots information. John used various names of his homeland and I am sure that was because of the area changing it's name at the time.
I really just would like to know Helen's name but I guess I can go to Milwaukee for the death certificate, hopefully it will be listed.
