Origin
Meaning and origin of Caldrone
The surname Caldrone has its origins in Italy, specifically in the regions of Tuscany and Umbria, dating back to the 13th century. It is believed to be derived from the Italian word "calderone," which means "large cauldron" or "kettle." This suggests that the name may have been originally associated with metalworkers or those involved in the production or use of cauldrons.
One of the earliest recorded instances of the name can be found in a document from the city of Perugia in 1274, where a certain Guido Caldrone is mentioned as a craftsman. This indicates that the name was already established in the region during that time period. The name also appears in various municipal records and tax rolls from the 14th and 15th centuries in towns such as Siena and Arezzo.
In the 16th century, a notable figure named Giovanni Battista Caldrone (1525-1599) was a renowned architect and engineer from Siena. He was responsible for the design and construction of several notable buildings and fortifications in his hometown and other parts of Tuscany. His works are considered important examples of Renaissance architecture in the region.
Another prominent individual with the surname was Tommaso Caldrone (1670-1738), a Baroque painter from Perugia. He was renowned for his religious and mythological works, many of which can still be found in churches and galleries throughout Umbria and neighboring regions.
During the 18th century, a branch of the Caldrone family settled in the city of Naples, where they became respected members of the local nobility. One of their descendants, Vincenzo Caldrone (1789-1867), was a prominent lawyer and politician who served as a member of the Neapolitan Parliament during the turbulent years of the Risorgimento.
In the 19th century, a notable figure was Giuseppe Caldrone (1825-1898), a scholar and linguist from Tuscany. He is known for his contributions to the study of Etruscan language and culture, as well as his translations of ancient Greek and Latin texts.
As the name spread beyond its original regions, variations in spelling emerged, such as Caldroni, Caldron, and Caldrone. These variations can be found in historical records from different parts of Italy and other European countries where Italian immigrants settled.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers.
