The origin of Italian surnames dates back from the end of the 1500s when parish priests were required to register parishioners with their Christian names and surnames in order to stop marriages between blood relatives.
Surnames come from different sources: first names, nicknames, geographic locations, professions, objects and titles, but each Italian region has adopted some types more than others with different spelling variations. Tracing these sources and variations is part of genealogical research and unveils an important part of family history and Italian heritage.
