Baal Shem Tov, Israel ben Eliezar Isserles - Baal Shem Tov y-dna

Hi Randy:
My wife Rose Hager Galston is a Female Line to the Baal. We were contacted by someone a few years back but he couldn't use her or our son Joel because it broke the male line. However they asked for Roses late brother Bruce's son...our nephew Eric Hager and he did do the DNA work with them and there was a report of sorts...Maybe that might help you?
Good Luck, Norm Galston

There is an author who says he tested three pedigreed descendants of the Baal Shem Tov and the Terminal clade was J-Z6048

The Baal Shem Tov
Yisrael ben Eliezer (c. 1698–1760), known as the Baal Shem Tov or Besht, was a Jewish
mystical rabbi considered to be the founder of Chassidic Judaism.26
We have tested three pedigreed patrilineal descendants of the Baal Shem Tov whose YDNA results genetically matched. We received a surprising result when a pedigreed
descendant of another notable rabbi matched the Y-DNA genetic signature, indicating that
this rabbi and the Baal Shem Tov may share a common ancestor. We are in the process of
identifying and testing other pedigreed descendants to help clarify this issue.
The predicted haplogroup to which the pedigreed descendants belong is J-M172; the
confirmed haplogroup, as reported through a J2–M172 SNP Pack test, is J-Z6048; we are
currently awaiting additional confirmation from the results of a Big Y-700 test. The
pedigreed descendants have an average of 37 genetic matches at 37 STR markers,
representing 25 different surnames for genealogically relevant genetic matches (≥33/37
STR markers; the 90% probability prediction for the TMRCA27 is within 12 generations).
We have recently discovered original census documents enumerating the Baal Shem Tov
and his family members; we plan to publish these findings in our forthcoming book.
