I have read these posts on double surnames with great interest. My father (Martinic) was born on the island of Brac in Dalmatia. While researching his mother's family from the town of Milna I have come across many of them. (note: the church records are all written in Italian and the names are in Italian form) For example, I have ancestors named Bonasich Prati. The Bonasich/Bonacic family has at least 3 different double surname forms. These appear to be of the type where a name has been added to distinguish branches of the family. This makes even more sense when you can actually get a feel of how many people are named Bonasich in a town of only a few hundred people. "Intermarriage", such as marrying someone from a neighboring town was relatively rare. There is, though, another possible explanation. Old timers in my family have told me the Martinich family was part of the Carstulovich/Krstulovic clan. This is certainly borne out by the frequency of Carstulovich double surnames in the towns of Milna and Bobovisca. Does any one know more of Croatian clans and clan names. Thanks, Don Martinich >I read Frank's explanation of hyphenated surnames with great interest. My >Hogac' line gets longer and longer as I move back in time, mutating into >Ivoc-Hogac, and even earlier, Norsic-Ivoc-Hogac. And to make it even more >fun, they keep moving around the order of the surnames (even with the same >couple). I can only hope as I move from the 1800s to the 1700s (the >microfilms exist, they are just very difficult to read) that we don't move >to quadruple or quintuple names. LOL >
