Rose Klestil Hadac (wife of Frank Hadac) of Kojakovice was a third cousin of my great-great grandmother Rozalie Bruzek Pesek (1856-1938). Rozalie was born in Petrovice, near Trebon. She immigrated to Chicago with her husband Frantisek Pesek in 1880. Our nearest common ancestor is Josef Klestil (d.1808, Kojakovice 7); he was the great-great grandfather of both Rozalie Pesek and Rose Hadac.
If you wish,I would be glad to exchange genealogical information with you.
