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