Volin, Wolin, Wolyn

I am looking for ancestors of Jan Volin, b1865, in Kozojedy, Plzen region. Par. Jan Volin and Anna Nemecova. The surname is written in successive church records as Volin, Wolin, or Wolyn. Jan emigrated to the Chicago, US, arr. 1882. He married Anna Slad in Chicago on 23-Apr-1885. Any information on his par., gpar., or ggpar., would be most appreciated.
