Dagostino History, Family Crest & Coats of Arms
The Emilia Romagna region of Italy is the locale where the Dagostino surname was first found. Although the people in this region were at one time known by only a single, personal name, it later became necessary for them to adopt a second name to identify themselves as populations grew and travel became more frequent. The process of adopting fixed hereditary surnames was not complete until the modern era, but the use of hereditary family names in Italy began in the 10th and 11th centuries. Dagostino is one of the Italian patronymic surnames, created from the father's given name. The surname Dagostino came from the personal name Agostino. This personal name is derived from the Latin word "augustus," which means "favored with good omens."
