I don't have Udovich in my tree or any surnames mentioned except Intihar from Staritrg pri Lozu a hamlet outside Loz and Likar from Godovic.
Your Intihars from Rakek could be distant relatives. There are Intihars all around that area and south towards mine.
Have you tried Facebook group Slovenian genealogy 2000? You can make good connections there and learn about available research resources through the very helpful regulars there.You may then also find info regarding the Ljubljana archdiocese who can do research for you. Good luck!!!
