Polish Y-DNA by Voivodeship (2.700 samples)

[Rethel]

Btw, much more interesting is high C in central regions.

Wow, Poland has Holy Cross Voivodeship. What a nice name, a true Christian country!

Wow, Poland has Holy Cross Voivodeship. What a nice name, a true Christian country!

Świętokrzyskie (święty/święto - holy, krzyż/krzyskie - cross)

[Ion Basescul]

A lot.
People living in Lebusland and Lower Silesia are migrants mainly from Ukraine.
In 1945 all, 100% people living there migrated to the West.
There is no reason to bind living there I-people with Germans.
These are I-people from western Ukraine, probably mostly I2.
And btw, I1 is not a germanic special haplgroup.

This is what you are referring to?

[Ülev]

and till 1950 Żary and Żagań area was in Dolnośląskie (Lower Silesia), this is why I see so many Dmytros and Zlatas here (in the sense if phenotype)

[Aren]

4% N indicates rather significant Baltic input in modern Poles.

[Rethel]

Wow, Poland has Holy Cross Voivodeship. What a nice name, a true Christian country!

Holy Cross - name of the mountain peak.
Holycrossish mountains - name for the mountains.
And from that is Holycrossish Voyevodenship.

In everyday speech probably noone even notice the etymology.

But actually you are right, we have a province named like Holy Cross

[Peterski]

This is what you are referring to?

Yes, only a minority of population in this area is pre-war, the majority came from elsewhere after WW2.

I put this data on Wikipedia here: https://en.wikipedia.org/wiki/Recove...to_1950_census

Here you have data by county for pre-war locals (autochthons - with German citizenship as of 1939):

AutochthonsZO.zip

Note that among these autochthons were both ethnic Poles (who had been Polish minority in Germany before 1939), as well as Germans who stayed in Poland (although officially German minority was not recognized in Communist Poland), as well as people who identified as "Silesians" etc.:



And here a map I made showing the percent of people from the USSR (Former East Poland) by county:



And here is how it looks like by voivodeship (not by county) today, ancestry from the USSR ("Kresy"):



I can make similar maps showing the percentage of people from each region, in each county, in 1950.

[Viridian1]

Łódzkie R1a 68%

Łódzkie R1a 68%
