Great. Thanks! Very interesting for me, because nearly 60% of my known ancestry is from "East Germany" (however, I consider Mecklenburg more as North German than as East German because of the origin of the majority of the population). My ancestry: Mecklenburg 39.4%, Brandenburg 10.9%, Thuringia 5.5%, Bohemia 1.8% etc.... 3 of my great-grandfathers are from Mecklenburg, 1 from Thuringia, 1 great-grandmother is from Brandenburg.
My Eurogenes K36 using your categories: NW Euro 41.14, SW Euro 18.47, Balkanid 5.69, NE Euro 11.22, Fennoscandian 13.01, Central Euro 8.72, Caucasic 1.72.

Here is my PCA with all individual samples. Czechs pull towards South-West Euro admixtures (Iberian, Italian, etc.) while East Germans pull towards NW Euro admixtures (North Sea, North Atlantic, etc.):

Green - Poles, Red - Czechs, Blue (including Light Blue) - Germans

Here I added East Slavic labels (averages). Label "Lviv" = Poles from Lviv, not Ukrainians:

"Austria" = East Austrians (mix of regions but not Tyrol, which plots much further west):



East Slavic area shown:



Edit: Of course UA Vitebsk should be BY Vitebsk (as Vitebsk is in Belarus).

What surprised me a little bit is that ethnic Poles from Lviv and surrounding areas plot more to the west than geography would suggest. They plot close to Lesser Poles and close to Upper Silesians. Map posted below show them as SE-Kresy (South-East Kresy). On the other hand, Poles from Wilno and Grodno region are clearly Baltic-shifted and plot close to Belarusians and Lithuanians.

What I noticed is that Mecklenburg is less Slavic-shifted than Vorpommern and Pommern.

BTW, is Rostock area counted as Mecklenburg or already Vorpommern?

Rostock is Mecklenburg.

Rostock is Mecklenburg.

So Rostock area is already genetically more Wendish than some other samples from Mecklenburg.

The coastal areas of Mecklenburg and Pomerania experienced more old-German settlement than the inner land. This is because of the heavy and good soils there. In spite of they are good, the Slavs could not really exploate them because there was needed an iron plow, which they did not have available, but the old-Germans. Parts of the inner land remaind Slavic for rather long times. As far west as in eastern lower Saxony there is the Wendland, where there was the last Slavic language spoken til mid 18th century. I expect this circumstances to show up genetically too. BUT: The more west Wends were the more they have probably assimilated smaller parts of prior Germanics.

Btw. the Slavic expansion - at least the westward one - is one of the big conundrums in history. From AD 1 till End of migration period (i. e. abt. 500 years) Germanics with an enormous historic "noise" managed to push the ethnic border some 100 or 150 km towards former Roman Empire. And then the Slavs expanded kind of "overnight" to cover half of Europe till the Line Kiel - Trieste. And half of "Magna Germania" just dissolved quite without any historic narrative. This is just incredible.

There are two big events touching identity of Germans east of the Elbe/Saale rivers. One is the old-German colonisation from, say, AD 900 to AD 1900. A how big proportion of the Germans east of Elbe/Saale rivers are old-Germans (per AD 900) and how much are Western Slavs? And the other event is the Slavic expansion. A how big proportion of Western Slavs are "originally" Slavs from north-east slopes of Carpathians and what´s the rest?

This question gets more complicated when one gets aware of the "rest" must not necessary be Germanics, at least not in a maybe expected sense. Eastern Germanics had germanized Celtics in Silesia, Bohemia, Moravia and also Slovakia, probably also in lesser Poland. But all these inhabitants were of course not Celts proper from Southern Germany, but to notable proportions celticised earlier inhabitants. No matter how the IE people originally between Germanics and Slavs are to be called, "Northern Illyrians" or whatever, they ought to be "part of the game"...
