Vlasic Family History
Vlasic Name Meaning
Croatian and Serbian (Vlašić); Slovenian (Vlašič): patronymic from the ethnic name Vlah meaning ‘Vlach Wallachian Aromanian’ (see Vlachos ) but in the past also used to denote in Croatia a Serb or a member of Orthodox Church and in Dalmatia (Croatia) and Lower Carniola (Slovenia) a Croatian or Serbian refugee from the Turks (i.e. the Ottoman Empire). Compare Lasich 3 and Croatian and Serbian (Vlašić rarely Vlasić): patronymic from the personal names Vlaho and Vlasije both derived from a name of a Christian saint from Greek Vlasios Latin Blasius . The surnames Vlašić and Vlasić are (very) rare in Serbia.
