According to Michael Pizer: The Perlmutter family came from the neighbouring town of Przedecz to Klodawa to manage a large flour mill owned by the Krzewacki family. The
Perlmutters lived in the Krzewacki home, as well as managing the mill. There were two Perlmutters, Guthca and Eda who survived the war and moved to Israel.

Per email from Evelyn Marczak, 1/17/07: "For sure our part of the Marczak family was from Klodawa. The other side of the Polish branch is Perlmutter"....Also, from another Evelyn Marczak email on 6/17/07: "Yes...our family was involved in mills."
