Thanks for the info. I do believe that John is the brother of Joseph Ignaczynski. According to Joseph's obituary, he had a brother John that lived in the US. A family member also remembers that her father had a uncle named John in Detroit but didn't know him well. John and Joseph also had a brother named Marcel in France. Do you know what cemetery John is buried? I found him in the 1940 Census in the Eloise Hospital.
