I'm hoping that even after a decade I get a reply. I am researching my aunt's lines. Her parents are Martin and Margaret [Luzovich] Sever. They came from Austria to America between Mar 1890 and Dec 1891. On the 1910 Census for White Twp., St. Louis Co., Minnesota the language is listed as Slovenian.
Margaret [Luzovich] Sever born 24 Dec 1863 (Jugoslavia or Austria) and died 6 Oct 1950 (Midway Twp., St. Louis Co., Minnesota. Her parents are John and Mary [Zorman] Luzovich. Are these people any relation to your Luzovich family?
