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.
