Vich, vič, vić. General suffix among probably all Slavic nations but more prevalent among some than others. It usually tells of one of your ancestors name for example Jovanović is son of Jovan but that’s not in all cases but definitely most. These surnames are mostly “static” nowadays but i assume long ago ones surname changed according to your fathers name.

Its exclusively my opinion so it can’t be for sure but i believe that it is more prevalent among nations that kept tribalistic elements for longer.
