Margolios Family Tree Scroll down . . .
Mendel and Sheindel also had seven daughters, one of whom married Mordechai Mardosh Auerbach. They had a son- Rabbi Arye Leib, and a daughter-Sheinza Auerbach.
Once Sheinza married her cousin Tzvi Hirsch, (mutual grandchildren of Mendel and Sheindel Margolioth), both her and her brother Arye Leib adopted their original name ‘Margolioth
Arye Leib was a Torah giant, renowned Gaon in the revealed and esoteric aspects. Yet the author of Elef Margolioth concedes that his father's name remains a mystery.
Tzvi Hirsch Margolioth, Av Bais Din of Yezlavich, married Sheinza Auerbach, sister of Harav HaGoan Ariyeh Leib Auerbach, Av Bais Din of Stanislaw.
Sheinza and Ariyeh Leib were the children of Harav HaGoan Mordechai Mardosh Auerbach Av Bais Din of Stanislaw. In the Magnum Opus Elef Margolioth, Rabbi Wunder concedes that Ariyeh Leib
s fathers name remains a mystery.
(In keeping with the family tradition) Ariyeh Leib (Auerbach- Margolioth) had a daughter Raizel married her cousin Rabbi Meir Margolioth, the son of Tzvi Hirsch; and Sheinza Margolioth/ Auerbach.
This explains the difficulty Rabbi Wunder had in identifying the lineage of the Saintly Ariyeh Leib: While he was born to the esteemed Rabbi Mordechai Mardush Auerbach, he reverted his name to Margolioth after his maternal Grandparents, Mendel and Raizel.
In addition to his sister Sheinza marrying Tzvi Hirsch Margolioth, his daughter Raizel now became married to his nephew, Rabbi Meir Margolioth, the son of his sister, Sheinza Auerbach/Margolioth.
Tzvi Hirsh and Sheinza had two sons, Yitzchak Dov and Meir, who were “of the first Talmidim of the Baal Shem Tov” (prior to his Hisgalut (revelation) as Tzaddik (Saint) and were referred to by the BSHT as his closest (original) students (also referred to as to as “Chasidim Harishonim”).
