This sample contains minimal amounts of Germanic and Levantine ancestry, resulting in little overfitting.

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.

The model was based on u/Hour_Might_9153's model; I just added a Czech source for Ashkenazi Jews.
