Thanks to Radovan Tadej, of Zlobin, Croatia, author of "In search of the lost people of Zlobin" (English), I have just found out that the surname that was handed down to us as Schubert was actually Subat (diacritic marks are missing, but they would indicate the Sh sound). My husband's great-grandfather immigrated from Zlobin, Croatia to Fulton County, Illinois approximately 1895. The family had been in Zlobin, on the Adriatic Coast, for several generations. I am interested in hearing more from anyone who may be related.
