I'm an Australian looking to apply for Hungarian citizenship via ancestry. My Grandfather was born in Hungary and moved to Australia after the war. I have all of his documents, (birth certificate, military ID, passport, etc), but I don't have access to his marriage certificate. I contacted the consulate in Canberra and they're telling me I need the marriage certificate, but I'm reading accounts from people saying they were able to get citizenship just by showing the ancestral lineage with birth certificates.
Does anyone know whether they actually need the grandparent's marriage certificate?
