Joseph Yasgur's birthdate

Joseph Yasgur's tombstone says he was 60 years old when he died on December 1, 1950, putting his birthdate at 1890. But his Petition for Naturalization that he filled out and signed in 1920 says he was born September 1, 1892, which would have made him 58 when he died. For the purpose of this tree, we're going to assume that his signed, 1920 Petition for Naturalization is correct.
