You are right, something does not add up.
He is born on Feb. 12, 1892 in NJ but than the obituary has him coming here [from where] 30 years ago.
Anything in his state marriage application? Did he and his wife get married in the church? What religion? Do you have his Death Certificate?
Do you know where he is buried? Did he come to America as Iwan/Ivan PET.....? If that is what his father's name was?
If I could unscramble and locate the "Tamliow, Russia and "Spascai, Poland than you would be in business to continue. For sure with Gabriel/Gavril it is Krytyszyn, Belarus.
