The Lithuanian family name Ivaskevicius is classified as being of personal name origin. The appellation (name or title) originated from "Ivask", a form of "Ivan". "Ivan" is one of several Slavic forms of the personal name "Johannes". "Johannes" is the Latin rendering of the Hebrew "Jehochanan", meaning "God is Gracious". "Evicius" is a patronymic suffix (Son of), hence the original bearer of the surname Ivaskevicius would have been the "Son of Ivask" or "Child of those that believe God is Gracious". The name began in Lithuania in the Fifteenth century with European Christians choosing personal names from the Bible. It is believed that "John the Baptist" is biblical name chosen.
