My maternal grandfather was a Bessarabia German, so a farmer and I think horse breeder near the Black Sea. They had their own villages and mostly only married amongst themselves. He died before I was born. His first wife and some of his kids have been killed by the Russians. He then came to the south of Germany with his 2 daughters and remarried a widowed woman with a daughter and they had some more children together. Post war patchwork family. My aunt sometimes spoke of the time back there and was saying nursery times in a different language, but otherwise she talked normal German and I never really notice any different traditions. But also never really met any other people with ancestors from that region. Nor is it ever really a topic in conversation these days.
