I am researching my husband's family "Kac" Bencion & Brindel Kac from Warsaw Poland before 1914. After 1914 moved to Rotne (Rokitno) Poland. Brokering fodder(hay, grain & straw to the Austrian army). The children of Bencion were; Hassa, Jonah, Aron, Sheftel and others. Sheftel is my husband's father who came to the US in the late 1930's. We would like any information on any other family in Poland. Also possibly the area of Kewel (Kowel or Kovel) K. Kass (Kac)
