From the 1920 census it shows that Kristina Hlad Navratil was born in Bohemia. It also shows a grandmother named Jossey (short for Josefa) Hlad living with them in Chicago. On the marriage records from St. Ludmilla Catholic church in Chicago it shows that she is from Suleberg or Sulcberg. I have checked on my map of the Czech Republic and Slovakia (which shows every little village) but there is no name like that. Kristina's father is listed as Jan Hlad and mother is Josefa Spurna, both from Suleberg/Sulcberg. Sorry that I can not give you more information. Good luck in your research. Kelli
