Hi,
My wife is Ljubic. His grandfather Nicolas Ljubic immigrate to Argentina because the ship sank (Principesa Mafalda). He was in reality going to USA where lived his brother Ivan Ljubic. Some (Ljubic) relatives of her live actually in California, USA. They are Ivan Ljubich (son) and his sons. Do you know them ? My wife Julieta Ljubic knows them. In fact the family name Ljubic was changed by error by "LjubicH" when he entered Argentina, but it is Ljubic...
Bye !
Enrique.-
