In the 16th century, the name appears in various documents from the region of Abruzzo, particularly in the town of Chieti. Records from this era indicate that a branch of the DeMayo family owned land and vineyards in the area.

As the name spread throughout Italy, it underwent slight variations in spelling, with forms such as DeMAIO, DeMAYO, and DiMAIO being documented in different regions. These variations likely arose due to regional dialects and the transcription of the name by scribes.
