I just received the death certificate in the mail today. This John G. Schuler in Chicago, Illinois was born on June 8, 1873. He died on November 16, 1935.
The daughter who completed the death certificate, Cecelia A. Schuler, stated that her father was born in Chicago, Illinois and that his father's name was Michael Schuler from Germany. No information was given for John's mother. I assume the information about John's place of birth and father's name is incorrect.
More likely, he is the John Schuller who was born in 1873 in Hennepin, MN. I was hoping that his death certificate stated that his parents were Peter Schuller and Maria Gillner.
