Origin
Meaning and origin of Lonetti
The surname Lonetti originated in Italy during the late medieval period, specifically in the regions of Campania and Calabria in Southern Italy. It is believed to be a locative name derived from the Italian word "lungo," meaning "long," which could refer to a person living near a long street or road, or possibly a tall or lanky individual.
One of the earliest recorded instances of the name Lonetti can be found in the Cedolario Napoletano, a collection of historical documents from the Kingdom of Naples, dating back to the 14th century. The name appears as "Lonetto" in these records, likely an earlier spelling variation.
In the 15th century, the Lonetti family is mentioned in the Catasto Onciario, a tax record from the Kingdom of Sicily, indicating their presence in the town of Reggio Calabria. This suggests that the name had spread from its original location in Campania to the nearby region of Calabria.
During the Renaissance period, a notable individual bearing the name Lonetti was Girolamo Lonetti, a skilled painter born in Naples in 1506. His works, including religious frescoes and portraits, adorned several churches and noble residences in Naples and its surrounding areas.
In the 17th century, the Lonetti family gained prominence in the town of Trani, located in the Apulia region of Southern Italy. Records from this era show several members of the family holding positions of importance, such as notaries and landowners.
Fast-forwarding to the 19th century, the name Lonetti gained international recognition with the birth of Giuseppe Lonetti (1828-1902), an Italian-American sculptor and artist. Born in Naples, he emigrated to the United States and became renowned for his marble and bronze sculptures, many of which can be found in museums and public spaces across the country.
Another prominent figure bearing the Lonetti surname was Vincenzo Lonetti (1890-1968), an Italian jurist and politician who served as the President of the Constitutional Court of Italy from 1953 to 1960.
Despite its Italian origins, the Lonetti name has also spread to other parts of the world through emigration and migration. For instance, Pietro Lonetti (1932-2018) was a Brazilian actor and playwright of Italian descent, known for his contributions to the theater scene in São Paulo.

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. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Lonetti surname at the time of the 2020 Census, not any inherent property of the name itself.
