MyHeritage DNA results of my grandma. She is a German from Russia and her roots go back to West Prussia. Her ancestors migrated from West Prussia to the Planer colonies near Mariupol, thats why they are also called Black Sea Germans. Pointing out that she is from West Prussia because many other Germans from Russia came from West and South Germany, so their genetic makeup will be different.

Thanks for share! MyHeritage is quite inaccurate in my opinion.. the most complete in ancestry to me is 24Genetics (https://24genetics.ru/) with more than 400 regions. You can do it also from 23andme raw data
so your Grandpa was 25 % West European ( German) and your Grandma Zero Precent West European , what kind of Germans are you ? 🙂
