Some key findings:

* There were at least 129 distinct mtDNA haplogroup founders and joiners in Ashkenazic communities whose haplogroups survived to modern times and possibly as many as 136.

* Ashkenazic Jews remain genetically linked to a significant degree to other types of Jewish populations, not only paternally but maternally as well.  Thus, for example, mtDNA haplogroup HV1b2 is shared between Ashkenazic, Romaniote, and Mountain Jews.

* The majority of Ashkenazic mtDNA haplogroups did not originate with Italian women.

* Two of the four largest lineages, K1a9 and K2a2a1, did not originate in Europe.

* There are six K branches among Ashkenazim, not only three.

* There are three N1b branches among Ashkenazim, not only one.

* Some Ashkenazic maternal lines, such as H7j and V7a, originated with Germanic and Slavic women who converted to Judaism.

* There are some Middle Eastern mtDNA haplogroups in Ashkenazim, such as K1a9 and R0a2m, that could be Israelite lineages.

* The Ashkenazic variety of mtDNA haplogroup X2b7 is closest to Spaniards.

* The Ashkenazic variety of mtDNA haplogroup N9a3 is close to Turkic-speaking Bashkirs.
