Israel Pickholtz presents a puzzle of sorts. The patronymic he
identifies as Benyamin is fine, but the second patronym could also be
a matronym? Boneh could be a feminine form (per Kolatch) and might
suggest the mother. If this is so, then the two Zalmans could be the
same. In the absence of more documented information, the issue is
still fuzzy.
