I am searching for my Bohemian ancestors who came to New York State in the 1800's. The majority settled on Long Island. I am hitting a brick wall. I am trying to find out specifically what town/village they came from in what was Bohemia. Vincent and Marie Sigmund, were the parents of Johanna Sigmund b. abt 1834, who married Alois Kopriva b. abt 1835. Their daughter Anna married Josef Jicinsky, b. abt 1853, whose father was Franz b. abt 1830.
