Judis Alpert

Source: The Unbroken Chain, Vol 1, Third Edition, 2017 by Neil Rosenstein.

Neil Rosenstein has the sons in a chapter on the Efrati and Itelson family. The sons took three distinct surnames: Prozner (from Pruzhany), Efrati, and Itelson (son of Itel, their mother).

He has the two daughters in the next chapter about the Bacharach family. One daughter married R' Yehoshua Heshel Bacharach and that chapter gives the couple's descendants, starting on page 146.

All he says about the second daughter is "G10.8 Wife of R. Shabtai (see fn 249)". Fn. 249 says she is only mentioned in Divre Dodim by R' Mordechai David Alpert published in 1902. Also page 146 of The Unbroken Chain, Vol 1, Third Edition.

Very interesting. I don't know where her given name, Judis, came from in the Geni tree.
