Pickholz - Hersch Pickholz of Podkamen married Jutte-Leah Kwoczka. Children were born 1877-1897.
Pollak - Basche Pollak of nearby Jezierne married Mordecai-Meir Kwoczka. Children include Jutte-Lea Pickholz, probably Pinkas Kwoczka and perhaps Rachmiel Kwoczka.
Franzos - Feige Franzos married Rachmiel Kwoczka. Children were born 1894-1907. Feige and Rachmiel were supposedly (first?) cousins. There is also a Franzos-Pollak marriage, which may fit into this structure..
Schapira - Beile Rachel Schapiro of Brody married Mendel Kwoczka. They had children in the 1870's. She was likely a second wife.
Zwiebel - Jutte-Leah Zwiebel married Pinkas Kwoczka. It is not clear if this Jutte-Leah is connected to the Kwoczkas who have two Jutte-Leah of their own. The Zwiebels are from Zbarazh and one of their descendants married a daughter of Hersch Pickholz.
And maybe...
Szwadron - when Rachmiel Kwoczka entered
the US, his passenger list said he was going to his cousin Hersh Szwadron.
Szwadron is a Zalosce name.
