Genealogy / Motyl - Tracing My Polish Roots for the 1st time [28]

I am trying to find maiden name for my grandmother, Stella or Sanistlava Jankowski. She was born in Oszmiana, Poland on January 6, 1882. She married Jozef Jankowski there on May 20,1904. She had a son there on June 8, 1905. She emigrated from there with him to America from Hamburg, Germany on the SS Blucher arriving in New york City on October 29,1905. She then went to Naugatuck, Connecticut and lived there until her death on Oct.19,1951
