I am uncertain if John is really a brother of Joseph, however they lived at the same address in the 1920 census and were only 2 years apart in age, so it seems like that they were siblings even though I haven't located an obituary or other documents to confirm the relationship.

Dear Sandra,
I know the place of the burial of Apolonia Oprzadek-she has a tomb and her husbend Andrzej Oprzadek-he doesn't have one. It is in Poland in Brzostek. One day ill go there and check the dates written on it.They are the parents of Jan , Frank and August who come to USA about 1920s. My grandfather was theirs the youngest brother. His name was Jozef(Joseph)
