This is probably the largest number of samples I've ever used in a G25 model, from various Ashkenazi Jews. Razi sent me his and his wife's coordinates so I could use them as a proxy here.
I selected samples from Erfut with Northern European ancestry greater than 29%.
Likely descendants of Knaan Jews, who in turn migrated eastward from the Holy Roman Empire through Ashkenazi centers in Austria and the Rhineland, we can observe very low germanic ancestry. Compared to modern Ashkenazim, who may have up to 10% Germanic ancestry, this suggests that smaller-scale conversions in France and Germany may have persisted until the end of the Middle Ages.
Why do Iraqi Arabs have more Arab ancestry than Arabs in Palestine, Syria, Lebanon, etc.? Why was Arab settlement stronger in Iraq and not in other countries of the Arab world?
The model was based on u/Hour_Might_9153's model; I just added a Czech source for Ashkenazi Jews.
