My ancestors also came from Novaya Ushitsa. My grandfather's name was Zelman Miron Wolfovich Bikman and my grandmother's name was Leah Wolfova Bikman (nee Rosenblum or Rosenblit or Rosenblatt). They left before WWI and came to Canada.
Perhaps we can share information to see if there is a connection? Other surnames are Marshtein & Zaltzman.
