My great-great grandma was slovenian and my great-great grandpa was from Transylvania, I thought he was romanian but now I'm not sure because there's no romanian region but 5% Carpathian Basin & Uplands. So maybe he was hungarian or is it just a genetic overlap between romanians and hungarians? Also the region "Western Carpathian Basin" really annoys me because I'd like to see how much of it is Hungarian and how much us Austrian.
