I found your information interested about the Kmett name. My grandfather and his wife left yugoslavia and moved to Argentina, during world war II. In Argentina, the customs dept. changed their last name to Cmet. His first name was Jose or Joseph in english. I wonder if he is related to any of your grandparents? My father visited Croatia a few years ago, and told me that their is a town named Kmett there, but that nobody that lives there has that last name. Family in that area, have moved to Triete, Italy.
