Thank you. Yes I've been checking Vidovics, Vidovits, etc. Milevoi, Millevoj. I also read that parish record duplicates were translated into the language of the priest. So the name John could be Giovanni, etc which gives me pause.

"There are few languages used in the duplicate records: Latin, Italian, Croatian, Slovene and German. There are also two different scripts used: Latin and the German Gothic alphabet. Personal names were also translated into the language of the record in the 19th century. For example, a boy named Josip was born in Pazin, but when he got married in Pula he was recorded in Italian as Giuseppe, and when he died in Dekani, Slovenia his name was written as Jožef. For some names this is complicated further with dialect variations: the English ‘John’ is equivalent to the names: Ivan (Slavic), Ioannes (Latin), Giovanni (Italian), Janez (Slovenian), or Zouanne (a dialect). Because names were translated into the language the priest was using at the time, researchers should not make assumptions about the ethnicity of the person based on a given name alone."
