I searched the Lodz Ghetto list for any surname sounding like FRANKENSZTAJN. Of the variants that turned up, only one was a girl with a first name starting with B, of the correct age for school #4b. Berucha is listed as Schuelerin also.Note that this is an "A.M." address, meaning his family lived at this address before and immediately after the creation of the ghetto.
