Hello George;
I have some information regarding Vucinovichs that are related to my mother's line of Miholovichs born in Lepetane.
The information I have was written by a John Miholovich, (I assume is a brother to my grandfather Vincent "Vicko" born 1857 in Lepetane). He lists names of relatives.
Anton Vucinovich, first cousin.
Gildo Vucinovich and his sister Gjova? Andrik second cousins.
His sister (John Miholovichs), Nina and her family: Gracia, Vicko & Rosa Vucinovich with a Buenos Aires address.
Are you related to any of these people? Are you corresponding with anyone in Lepetane regarding family history?
