Dr. simcha gershon bohrer Thanks for the inquiry. Here is some information to help with the research: 1) L816 is associated with R' Tzvi Elimelech Spira of Dynov keep in mind that L816 alone is not specific enough to compare to the R' Tzvi lineage, which has been tested in more detail to the J-FGC65704 level; you would need to do further testing to confirm a match to R' Tzvi's lineage, 2) there are currently three Jaffe haplogroups to my knowledge: a) one is in the J1a-Z640 branch, b) another is in the J2a-M410 branch, and c) another one mentioned by Private User is in the E-V13 branch. Both (a) and (b) have been tied via family trees to Baal Halevush, so which one is still uncertain. I have no family tree information regarding the E-V13 persons.
The ydna sample you tested (L816) cannot be part of these two known Jaffe branches (Z640 and M410), and therefore appears not to be connected to Baal Halevush, but could still be part of another Jaffe branch. The use of Jaffe as a name may be connected to various haplogroups, just as Margolis, Shapiro, etc. have several haplogroups. There is no one exclusive Jaffe haplogroup.
