Where the Caldaronello surname comes from
Caldaronello is a nickname of debated origin. The most solid explanation starts from the calderone, the large copper cauldron used to boil liquids. From there, most likely, it points to the coppersmith, the craftsman who made those vessels. The ending -ello sounds like an affectionate diminutive, almost a “little Caldarone.”
A surname of fire and copper
Caldaronello is so rare that the major surname dictionaries don’t give it an entry of its own. You have to look for its traces in town archives, where the family already appears in the first half of the 1800s. Another theory about its origin remains open, and one branch crossed the ocean before the 1900s. The PDF covers both.
Where the Caldaronellos live today
In Italy barely fifty people carry it, almost all of them in Sicily. Its heart is the countryside inland from Palermo, between the towns of Marineo and Ciminna. The few families in Piedmont, Emilia-Romagna and Abruzzo are recent, the result of the migrations of the 1900s. The PDF has the map and the countries around the world the Caldaronellos reached.
