Looking for descendants of Joseph/Barbara Wollenberg from Poland. Lived in far northern Minnesota. Barbara's maiden name may have been Lubianski. Joseph died between 1910 and 1920. Barbara then married Joseph "Frost" (Mrozek or Mroz??), also from Poland, before 1920. By 1930 she is a widow again. Her children were Michael, Helena, Joseph, Stanley, Leon or Leonard and Victoria Wollenberg. Barbara moved to Chicago with Leon and Victoria between 1920 and 1930. Stanley apparently came to Chicago too and married Mary (unknown maiden name).
