Dear fellow researchers,
Rabbi Mordechai WEITZ of Kalish (Kalisz) was one of the most
important genealogists before the holocaust.
However, only one of his books was published -- Ateret Paz (1937),
while other manuscripts have been presumably lost in the war.
These manuscripts are of major genealogical importance, e.g. Matteh
Horowitz (on the Horowitz family), Paz Na'eh (on Pozanan's rabbis),
Toledot Rabeinu Ba'al Tosefoth Yom Tov, another book on the
ETTINGA-LANDAU-MARGULIES families, and possibly more.
I would be interested to know if someone has information on writings
that have "survived" the war, and/or any copies made by others, of
the whole books or any parts thereof.
