Citizenship by descent - GGF year of birth.
Hello! I'm trying to understand if I'm eligible for citizenship by descent. My GGF was born in Gölnicbánya, Szepes. I have all documents in chain from me to my grandmother, his daughter (her birth certificate, where he's mentioned as the father, her marriage certificates, etc.). Also, he was repressed in Leningrad in 1938, and I have got a copy of his personal Arrestee Questionnaire, where the correct place of birth, his name, and patronymic are listed in Cyrillic, and my grandmother as his daughter as well. Also, thanks to r/csaladfakutatas, I have a scan with a baptism record from Gölnicbánya, with his Hungarian name (Andor Patz / Andrej Patz in Cyrillic) and father's name (Martin / Martyn in Cyrillic), which seems to be okay. The only issue I see is the birth year. In his Arrestee Questionnaire, it's June 14, 1875, but in the baptism record, it's June 14, 1874. I'm almost sure that this is my GGF record, as I didn't find any other matching records in Gelnica from 1873 to 1878. Could this year inconsistency be an issue? I have to say we don't have any other of his documents. Thanks for any advice.
