HI ALL-I have recently been visited by the geneology fairy. There was a VERY large family of hlavacek's that came from bohemia to the U.S. in the 1800's. Chances are most of us belong. or are part of the family who came after- or didn't come at all. in 1850or so Wenzel Hawaschik (hlavacek), wife Magdalen Stebor came to this country with children, ann, adfaline,Thomas, joseph, frantisek, barbora, and Mary. son thomas .m. Mary Steffel children:Anna, Mary, antonia,sophia, emil,frances, celeste, lucy, wenzel. son joseph m. sarah, children Jno, joseph, fredrica. Son frantisek m. Josepha children Rudolph and frank. those would be the ones carrying on the surname.
