Hi :-)
My grandma was a Hungarian citizen (born on 1928 in Nagykőrös, Hungary) but after WWII moved to a different country and later lost her Hungarian documents in a fire incident. She passed away in 2012.
My father is currently trying to obtain her birth certificate or at least locate her in the government's records so that he can register for the Hungarian citizenship, but we only know her full name, date of birth, her father's name, and her mother's first name (not maiden name). We also aren't exactly sure of the Hungarian spelling of their names, but I was able to find common spellings through search on FamilySearch, but still I'm not 100% sure.
The only family member in Hungary (my grandma's sister) we have contact with refuses to help us. My cousin even tried going to Hungary to work with government centers directly but they weren't able to locate her, saying she doesn't exist in their records (I assume because we aren't sure of the spelling)
Now my question is can I go anywhere with the information I have? Who would be the best person/entity to reach out to help "search" for my grandma's records? Any help would be extremely appreciated!
