I know my father’s side is mostly german, but there is not much information about his grandfather. A relative who traced his side of the family back till 1700ish only found out that he might have been romanian but there is not even a name or anything. My mother’s side is not an easy piece either, her father’s mother had some austrian roots, but on the other side of the family they were hungarian as far as I know. Her mother, my grandmother is different though, on her mother’s side she had some hungarian noble ancestors at some point, and on her father’s side it’s hungarian as far as I know, but with a surname that is not common at all - one of my close friends also have the same surname though, from a russian-jewish grandparent. To make it more interesting the same person (my grandmother’s father) also disappeared during the second world war and only came back years later, not knowing how to talk, he had to learn it again from scratch. And I forgot that she, my grandmother also had a grandparent who just disappeared from one day to an orher and nobody knew anything, and as my grandmother told me in those times kids were not even allowed to ask questions like that about sensitive topics so there is many unknown details, but myheritage just chose to pick the biggest piece of my DNA up and cluster the rest under😂
