Y-DNA haplogroups in Silesia before WW2

Hello Tomenable. I'm not convinced but to end this offtopic I will make my last post concerning Mecklenburg. You can reply to me using PM in a matter concerning this post :).
Hi Artmar,

It was probably not too low, really.

As of year 1950, "Vertriebene" were 42% or 45% (another source) of entire population of Mecklenburg:

1) This map shows 871,000 of them in Mecklenburg-Vorpommern in 1950 (so 41.7% of the total population):

2) But this table claims an even higher number - 981,000 (which is 45% of the total population as of 1950):

<LINK REMOVED - I can't post them and quote them>

Allright, so we now know something more. A simple fact - Mecklenburg was a region with higher participance of migrants. However, was it possibly connected with another fact, that this region remained relatively peaceful during the last months of WW2 in Europe? Maybe it's also connected with a fact, that many migrants were transported with a ships and it's a coastal region? Hamburg was bombed and so were other significant ports - Bremen and Kiel.

And again - were they just registered there and gathered in some kind of transit camps and later went elsewhere or they rather stayed? How many of them stayed? Have they settled mostly in cities/towns or on a countryside? Was there enough place to take ~40-45 % of new inhabitants? I guess not, because Mecklenburg wasn't affected by warfare - there weren't many perished people to be replaced.
Please also remember that it's 1950 and authorities had greater concerns than building block housing. It started later.

Mecklenburg had to be crowded. Migrant's didn't have a good perspectives there:
Older people told me that the post-WW2 refugees were rather unwelcome in Mecklenburg, so many of them moved further west, but I don't know how many.

So, if they didn't have enough place and were not welcome, they likely got displaced to other regions (or chosen to do so) after 1950. If not to West Germany with better opportunities, then probably to re-populate big cities which undergone a considerable loss of "human factor" - like Dresden or Berlin, among others.


And exact percentages for West Germany in 1950 and in 1961 can be found here:

<LINK REMOVED - I can't post them and quote them>

(from 1950 to 1961 many of them moved from East Germany to West Germany):

And here we are. How many of them actually left Mecklenburg after 1950? How many of them stayed until today or the moment of sampling a populations of Mecklenburg? What was their Y-DNA composition? We have to be sure that they had much of an R1a to double its frequency in that region.

Sample of Rebala consisted of 131 individuals for the whole region of Mecklenburg and it's considered to be representative. Sample for two single cities -Rostock and Greifswald, although we can't be certain on how many descendants of migrants were sampled here, numbered 200.

I'm well aware that migrants could've risen a frequency of R1a, since I have an eye on ~5000 R1a samples. The question is - was it a really significant rise? Do we know enough to say anything more than - "well, slight rise is likely but significant rise is in question"? We don't :). It remains a possibility but I have my own reasons to feel skeptical about it. Data that we have doesn't suffice.

Good argumenting and reasoning. Lot's of time is going to fly by till we get all genetic data to be sure how it went around. Well, at least we have fun guessing now, and check who was right later.
Thanks!

I may sound like a lingerer sometimes but I'm just long enough "in the topic". I've seen many population studies and how significantly the % can actually change depending on a sample and sampling methods. Tomenable may be right eventually but I feel a need of pacifying him a bit.
There is nothing wrong in saying "I don't know" or "I'm not sure".

PS. Hey neighbor, I used to live in Siedlce.
Pretty much unexpected, how come? You can write a PM to me :)

I thought it was my job here, lol. On other hand I love his energy and enthusiasm, and many good ideas.

Agree, likewise there is nothing wrong with using "perhaps" and "maybe" presenting new ideas or acknowledging shortcomings of our understanding.

I should find some time after work.
 
Frequencies of R1a in samples from East German and Austrian (Graz) cities:

Graz - 42,9%
Dresden - 32,6%
Rostock - 32,4%
Halle (Saale) - 30,3%
Leipzig - 27,1%
Berlin - 22,3%
Magdeburg - 21%
Greifswald - 19,2%
Hamburg - 16,8%

^ This data is from: Immel 2005; Kayser 2005, Roding 2007, Wiik 2008.

=============

In Rebala's sample from pre-war Mecklenburg, there was 13,7% of R1a.

In a modern sample from Rostock in Mecklenburg, there is 32,4% of R1a.

Greifswald has a lower share, but it is in Vorpommern, not Mecklenburg.

=============

The sample from Halle (an der Saale) has 30,34% R1a and 29,06% R1b:

R1a - 71 out of 234
R1b - 68 out of 234

Other haplogroups from this sample of 234:

I1 - 30
I2a - 18
J2a - 11
J2b - 7
J2 - 1
E1b - 12
G - 8
N - 3
J1 - 2
T - 1
H - 1
C - 1
 
As for Austria, frequencies of R1a differ vastly depending on region. For example:

The city of Graz - ca. 43% of R1a
North-East Tyrol - ca. 16% of R1a
South-East Tyrol - ca. 0% of R1a


Here a map illustrating this (R1a frequencies for East Tyrol are from Berger 2012):

One R1b sample could not be placed on the map because its location is only described as "Lower Silesia".

Out of the remaining 10 samples which could be placed, as many as 4 are in the region around Grünberg:

https://en.wikipedia.org/wiki/Zielona_Góra

So it seems that percent of R1b among Y-DNA was relatively high in North-Western part of Lower Silesia.
 
^ If we apply that line of divide, we get:

Upper Silesia - 48 samples of which 30 R1a = 62,5%
Lower Silesia - 48 samples of which 23 R1a = 47,9%

However:

Grünberg region - 11 samples of which 4 R1a = 36,4%
Rest of Lower Silesia - 37 samples of which 19 R1a = 51,4%


 
Subclades of R1a (excluding CTS6) in FTDNA "Polish Project" and in Silesian sample:

L260 is known as P-Type ("Polish Type") as it was named by Peter Gwozdz long ago.
 
I collected data on German Y-DNA haplogroups from peer-reviewed studies about modern populations, and from Family Tree DNA. Data from Family Tree DNA represents people who lived in the past - every customer provides information about place of birth of his oldest known ancestor. Thanks to this we can trace each customer's Y-DNA lineage to a particular place in the past. Samples from FTDNA represent frequencies of haplogroups in pre-1914 populations - effects of modern migrations are not visible.

=========================================

Here is a comparison of % of haplogroup R1a in various populations. You will see that there are large regional differences - and that East Germans have much more of R1a than West Germans. Also South-East Germans have more than North-East Germans:

I added data on R1a among some West Germanic, Celtic, Slavic and Baltic populations for comparison.

Samples for Lithuanians and Latvians refer to ethnic groups - minorities like Poles in Lithuania or Russians in Latvia aren't included.

* Data for inhabitants of Haale an der Saale includes only 234 men with German and German-Slavic surnames. The total sample was 419 - including 234 men with German or mixed German-Slavic and 185 men with purely Slavic surnames. However, among those with Slavic surnames there were probably also some recent immigrants, not only descendants of local Wends. Having German surname does not mean that ancestor wasn't Slavic in the Middle Ages - it just means that he became Germanized before surnames became popular. In East Germany, peasants started commonly using surnames only after Medieval times, in the Early Modern Era.

Based on that, I made a map of R1a in Germany (Mulheim not included, because I found this data after I made the map):

Im from North Western Germany. R-YP1337* here.
 
Interesting, one of the rare surnames in my tree appears, which is from a German region, but more likely to be of Slavic origin, and its R1a. But while its rare, its not so super rare as that there couldn't be different regional branches all around Silesia, Saxony, Bohemia.
