Aiello derives from the Latin areolum — a diminutive of area, meaning a small open space, threshing floor, or courtyard. The name was applied to settlements across southern Italy, and dozens of towns and villages carry the root: Aiello del Sabato in Campania, Aiello Calabro in Calabria, Aiello di Mel in Veneto. Families living in or near these places — or who migrated from them — carried the place-name as their own.
The surname is concentrated in Sicily and Calabria, where the great majority of Italian-American Aiello families originated. In the late nineteenth and early twentieth centuries, as the mezzogiorno (southern Italy) faced severe economic hardship under the post-Unification Italian state, hundreds of thousands of families emigrated. The Aiellos joined the great wave, settling most densely in New York and New Jersey, where the name became well-established in Italian-American communities.
The most famous American bearer of the name is Danny Aiello — born Daniel Louis Aiello Jr. in New York City in 1933 to a family with Neapolitan roots. His career spanned five decades, including an Academy Award nomination for Do the Right Thing (1989). In Italian-American culture, he embodied the Bronx-Italian working-class world that many Aiello families inhabited.
In Sicily, the name appears in records going back to medieval times. The Sicilian spelling Ajello — with a 'j' in place of 'i' — is the older form, reflecting the southern Italian tendency to write the consonantal 'i' as 'j'. Many American Aiello families have ancestors whose documents in Italy spell the name as Ajello.
If your family name is Aiello, you are almost certainly descended from southern Italians — Sicilians, Calabrians, or Campanians — who came to America in the great emigration of 1880–1920. The name plants you firmly in the Italian-American working-class tradition of New York and New Jersey, and in the sun-drenched landscapes of southern Italy where your ancestors threshed grain in small courtyards under Mediterranean skies.
