Adam,

Thank you for sharing your interesting thoughts here and elsewhere.  I've been closely following the discussions and data modeling of these Jews.

Although 5 particular mtDNA haplogroup branches were shared between Ashkenazim and Langobards, they are also shared with many other kinds of populations.  Plus, as Erikl86 said in the comments section of Eurogenes, "There is no proof that Lombards converted to Judaism".

And although the linguist Paul Wexler had suggested that some Avars could have converted to Judaism in the early Middle Ages, there is no documentary or genetic evidence for this, and scholars still debate the dating of Jewish-inscribed gravestones and the ethnic and religious identities of some of the people buried at the Chelarevo gravesite, where Avars were also buried (as I discussed at length in "The Jews of Khazaria, Third Edition" on pages 147-149).  Only some of them think any Jews were buried there, but even for those who believe Jews were, there are still major anthropological differences between that population and the Avar skeletons.

I continue to see Chinese and Khazarian contributions as the best explanations for East Asian and Siberian admixtures in 14th-21st century Ashkenazim and for the three East Eurasian maternal haplogroups in Ashkenazim.

I also believe evidence shows that all, or nearly all, Sephardic migrations into Ashkenazic lands occurred after 1492.  I agree with Erikl86's comments in Eurogenes that "There's also no proof for any substantial Sephardic migration in Germany that early on. Also, there doesn't seem to be any significant Sephardic subclades among these samples."

The few numbers of modern Western Ashkenazim from Alsace-Lorraine and southwestern Germany whose families remained genetically isolated from Eastern Ashkenazim (i.e., not descended at all from the back-migrations of some Eastern Ashkenazim into German-speaking lands) cluster much closer to Italki Jews and Sephardi Jews than Eastern Ashkenazim do.  We don't need to explain this by Sephardic migrations.  It's clear to me that those Western Ashkenazim are very similar to what 9th-century German Jews, recently arrived from Italy, would have been like.
