Stolarek et al: Genetic history of East-Central Europe...

[Dewsloth]

The Celto-Germanic admixture of today's Poles is ambiguously due to residual Germanic peoples of antiquity such as Goths, Vandals and Celtic Boians. However, most Germanic groups migrated to Pannonia, Hispania, North Africa and the Crimea.
2. from German settlers from the Middle Ages (German East Settlement) such as the Forest Germans, the new settlers come from Brandenburg, Saxony and also many from the Rhineland, Hessen, Swabia, Flanders... but also a third smaller aspect, German ones Second World War in the People's Republic of Poland and were assimilated (citizenship, marriage with Poles...)

Funny you should mention that, because the only known modern Spanish DF19 is on a small branch shared with a Polish and a German tester, and their FTDNA-calculated TMRCA is around 400CE. And the spanish sample’s surname is a patronymic supposedly referring to a Germanic tribal origin, such as the Visigoths.

Bad news: They only determined the mtdna haplogroup of the individual.

If I understand correctly, in Russia they do not do autosomal analysis for ancient samples. At least in earlier studies, they were limited to mitochondrial and Y-DNA only.

Well, as I see the researchers and institutes involved in this study are also the ones who are working on this project:

https://www.siriusuniversity.ru/research...oi-ravnini

The project description says: "For more than 100 samples of high quality and percentage of ancient human DNA, full-genome sequencing and bioinformatics analysis of the data obtained were carried out." So I believe we'll see the autosomal results for many ancient samples relevant to the slavic ethnogenesis, maybe even this sample's nuclear genome will be sequenced in the future.

Well, there are some labs in Russia that try to get autosomal data, but aDNA research in Russia is limited because of

1) Later start than the west
2) Systematic underfunding
3) Sanctions
4) Overreliance on prior anthropological/archeological/linguistic data
5) Some weird methodological quirks.

About the last part - the most well known Russian population geneticists, Balanovskys, have fixation on Y-DNA and mtDNA data and do not pay as much attention to autosomal data as they should have.

[FR9CZ6]

Ah, yes those sanctions. I guess the military expenditure and the war also cost a lot.
However, maybe some recent developments gonna help to boost up the russian archaeogenetic researches in the future.

“ Solopharm, a leading Russian pharmaceutical company, announces the completion of new laboratories to expand knowledge about the history of the ancient peoples of Russia.

The company's investments in the amount of 24 million rubles made it possible to build two laboratories for paleogenetic research. One of them is located on the territory of the European University in St. Petersburg, the second is at the Solopharm pharmaceutical plant.

These laboratories will become a scientific platform for conducting a large number of genetic tests at the intersection of archeology and genomics.”

There are obviously a lot of immigrants in Medieval Poland.

These can also be the Restgermanen, not necessarily recent immigrants.

I find it hard to believe that Goths and other Restgermanen survived in Poland another 500-600 years after the collapse of Wielbark and Przeworsk cultures. Recent immigration is much more probable.

I'm not saying that they survived, but that they were their genetic descendants.

They could be already Slavicized linguistically but still very Germanic autosomally.

How would you explain "young" Y-DNA lines such as R-S22194 (TMRCA 517 CE according to FTDNA, shared mostly with modern Western Germans and Theo der Pfeifenraucher) in Santok other than Medieval German migrations?

[Radko]

BTW, do you remember Germans buried in the 14th c. Lübeck (which was Slavic settlement in the past)? Some samples have been added to FTDNA.

For example HGH-1607 belongs to I-FT337024 (TMRCA 916 CE, shared with modern Danes, Germans and Brits).

And there was one "Eastern European" sample, but it looks like a Balto-Finnic rather than Slavic person.

Genealogically, Dmitry seems largely Kievan Rus, descending from multiple Rurikid branches on both sides, on his father's side he has a great-grandmother Maria of Ossetia and a gg-grandmother likely Helena Komnene (Byzantine); further back there is Swedish input. Dmitry's maternal grandmother is unknown to me.
