There is a Michael Kozac(ik) Sr., and a Anna Kozac(ic) on my husbands side of the family. Michael Kozacik would have been my husbands great-grandfather. They were a prominent Whiting family owning movie theaters and banks in Whiting. Michael Kozacik Jr. changed his name to Kaye. Michael Sr. came from Slovakia in the late 1880's along with a brother and cousin. Michael Jr. had 7 other brothers. Are we talking about the same family?
