Companies that claim Ashkenazi Jews are 100% European are incorrect. Ashkenazi DNA is a mix of Southern European and South West Asian (Middle East) DNA. Ashkenazim do not cluster with Eastern Europeans. PCA charts show that Ashkenazim cluster close to Southern Italians.
Eastern Europeans cluster directly to the east of North West Europeans, and in fact they overlap with some North West Europeans. A legitimate map of where Ashkenazim cluster would include Southern Italy, Tuscany, Northern Italy, Malta, Cyprus, Turkey, Armenia, Georgia, Azerbaijan, the Levantine countries, the Persian Gulf states, and the Arabian Peninsula states.
I did my test with Living DNA, and score a mixture of Southern European (South Italy, and North Italy), and South West Asian (South Caucasus, and Arabia).
