Etymology
D’Agostino is an Italian patronymic surname built from the personal name Agostino, the Italian form of Augustine. That name ultimately comes from Latin Augustinus, meaning “belonging to Augustus” or “venerable,” from augustus. In surname form, the prefix d’ or di means “of” or “from,” so the name originally identified a person as belonging to, or descended from, someone named Agostino.
History
The surname is strongly associated with Italy, especially southern Italian naming traditions where di/d’ surnames are common. It spread beyond Italy through migration in the late 19th and early 20th centuries, especially to the Americas. The apostrophe is often preserved in formal Italian spelling, though many records simplify it to Dagostino.
