Gaetani is a surname of both toponymic and patronymic origin, associated with the city of Gaeta, located in the province of Latina (Lazio). It is also connected to the personal name Gaetano, derived from the Latin Caietanus, meaning “native or inhabitant of Gaeta.”

Origin and Etymology

The authors agree that the surname has a dual origin. On the one hand, it may derive directly from the place name Gaeta; on the other, it may originate from the personal name Gaetano, which became widespread in Italy through Christian tradition and the cult of Saint Cajetan.

The name Gaetano comes from the Latin Caietanus, originally a demonym identifying someone from Gaeta. Over time, this designation became a personal name and later developed into a surname.

F. De Laurentiis points out that the form Gaetano preserves primarily the value of a personal name rather than merely a geographic designation, indicating that surnames of this family may have developed through different historical paths.

Distribution in Italy

E. Rossoni identifies the main areas of distribution of the surname Gaetani as:

• The province of Cosenza (Calabria).
• The Salento area in southern Puglia.
• Lazio.
• Marche.

The variant Gaetano is especially characteristic of Calabria, although it is also found in the area of Naples.

Historical Families

Rossoni records the presence of the noble Gaetani d'Aragona family around the 14th century. They were lords of Fondi, in the present-day province of Latina, and played an important role in the political and noble history of central and southern Italy.

Summary

Gaetani is a surname connected to the city of Gaeta and to the personal name Gaetano, both derived from the Latin Caietanus, meaning “native of Gaeta.” It may have either a toponymic or patronymic origin and has a long historical tradition in Italy, including associations with prominent noble families. Today it is found mainly in Calabria, Puglia, Lazio, and Marche.
