I suppose that your grandfather John was born on 8th December 1886 in Poland in the region called Kujawy. Some members of the family Szutenbach came to the USA at the end of the 19th and the beginning of the 20th century. Unfortunately, the different lines in the USA do not know how they are related to each other.
Do you maybe know whether your grandfather had a sister Helena (Helen) who also came to the USA and was married with Mr Kamedula?
Due to your answer your grandfather died about 1934. Is it possible that he died at the age of +/- 48 years?
