My great-grandparents were Harry and Rifka (Reva) Plavnick, whose children included Samuel (Simon), Fannie (Plavnick) Fleisch, Alex, Hyman, Rose (Plavnick) Lipkowitz, Samuel (Plavnick) Plavin, Max, Charles (Plavnick) Cooper, and another unknown daughter. This family was in Vitibsk, Belarus. Samuel (Simon) came to USA about 1905. My daughter is doing extensive research. Email me at plavnickpm at yahoo.com.
