I have one Cermak in my tree. Antonie Cermak (b abt 1856) married Jan Kroc who was born in Privetice 1854 and emmigrated to Chicago abt 1884 with 2 daughters, third was born here. It is possible she was also from Privetice.

All my Kroc family was from Privetice however my Kosar family were all born in Vejvanov a mere 4.8 km distant.
