[Ger-Poland-Volhynia] Wolf& Schlag or Schlack families

[MARTHA JACOBS]

My mother and her parents came from the Zhitomir area of then Prussia.
They were the only members of either family that came to this country in
1895.  I am looking for possible kin folks who may or may not still live
in the area.  The only reference I have is some old letters which is as
follows:
