Wife of R' Joshua Heschel Bacharach

The wife of R' Joshua Heschel Bacharach was a descendant of a line of rabbis in NE Poland and Lithuania, descendants of the Maharam of Padua. Their genealogy can be found in The Unbroken Chain Third Edition, volume One, 2017.

One branch of the family took the name Margolis, another branch took the name Rabinson (became Robinson), or 'rabbi's son'. She was the daughter of Itel, sister of Shmuel (Margolis line) and Asher the Great of Grodno (Rabinson line).

Itel's son's took various surnames, including Efrati, Prozner (from the town of Pruzhany), and Itelson, 'son of Itel'. It's likely incorrect that this woman had a surname, Efrati would have been the surname chosen by one of her brothers in the early 1800s. Her relative, David Tebele Efrati lived in Merecz (Lithuania near Trakai) in the mid 1800s and was a scholar. He wrote a genealogy of the family that later genealogists use.
