In 1657, the Doge of Venice, Bertuccio Valiero, decided to repopulate the town by bringing 15 families. Five of these families were of Orthodox religion, originally from the Cernizza region in Montenegro that had escaped from the Turkish occupation. Based on evidence, it is generally assumed that these Montenegrin settlers carried the surnames Brcela, Draković, Brajić, Vučeta, and Ljubotina. The remaining ten were of Roman Catholic religion but of unknown origin and are thought to be either of Croatian origin from Albania Veneta or of Albanian origin. However, these Catholic families soon emigrated from Peroj. Following the Cretan War of 1645–1669, twenty other families originally from Montenegro migrated to Peroj, amounting to 25 in total by 1677. These families remained in Peroj and until recently Serbo-Croatian was taught in the local schools due to their presence.
