According to a dictated note written by my great uncle, his
grandmother, Sarah Hinde KANTOR was a descendant of R' Chaim of
Volozhin and her "unterfierer" (that took her to her wedding) was R'
Itzaleh, R' Chaim's son. Sarah Hinde does not appear in any published
trees and supposedly was orphaned at a young age while R' Itzaleh (her
grandfather?) was still alive.

Sounds a bit like R'Itzaleh's daughter and son-in-law-LANDAU who both
passed away during his life time.

Does anyone have any knowledge of the above Sarah Hinde (maiden name
unknown to me).

TIA
