Dell’osso Coat of Arms Record & History

Dell’osso means “of the bone.” Osso is the Italian word for bone, and dell’ means “of the.” Names like this usually began as nicknames. A man might have been a butcher, or simply thin and bony, and the name stuck to his children and their children after them. Italian families started fixing surnames this way between the 1200s and 1400s.

The family shows up in the historical record in the south. The earliest noble records point to Morano Calabro, a hill town in Calabria, from the 1400s onward. The Dell’Osso there were people of standing: they owned a palazzo in the town and had their own burial places, which in that period meant real wealth and a recognised position.

One of the better-documented early figures is Leopardo Dell’Osso, a physician of the 1500s from Morano Calabro, remembered as a teacher of Fra’ Bernardo Milizia da Rogliano. Doctors were among the small educated class of the time, which fits a family already established locally.

Over the following centuries the name spread across the neighbouring southern regions. Branches settled at Bernalda in Basilicata, Bagnoli Irpino in Campania, and Lucera in Puglia. At Bernalda the family was counted among the local nobility, and a Luigi Dell’Osso served two terms as mayor of the town in the late 1800s.

The name is still rare. Fewer than 450 people carry it worldwide, and close to nine in ten of them are in Italy. The rest are mostly in the United States, Argentina and Belgium, taken there by emigration from the south. You will also see it written Dellosso, D’Osso and Dall’Osso, spelling shifted from one clerk and one parish register to the next.

The meaning of the name reaches the arms as well. One of the two recorded coats of arms shows a hound holding a bone, a picture of the name itself, which heralds called canting arms. It was a common way to make a shield instantly recognisable in a world where most people could not read.
