Origin
Meaning and origin of Lucidi
The surname Lucidi is of Italian origin, derived from the Latin word "lucidus" meaning "bright" or "shining." The earliest known records of this name can be traced back to the 12th century in the region of Tuscany, Italy.
Lucidi is believed to have originated as a nickname or descriptive name given to individuals with bright or radiant personalities or those who possessed a certain brightness or clarity in their appearance or demeanor. It may have also been given to those engaged in professions or trades that involved working with light or illumination, such as candle makers or lantern bearers.
One of the earliest recorded instances of the Lucidi name can be found in a 13th-century manuscript from the city of Siena, where a certain Guido Lucidi is mentioned as a prominent merchant and landowner. Another notable figure from this period was Giacomo Lucidi, a renowned artist and fresco painter active in Florence during the late 14th century.
In the 15th century, the Lucidi family gained prominence in the city of Pisa, where they were known for their involvement in the textile trade. One member of this family, Giovanni Lucidi (1425-1498), was a respected merchant and diplomat who represented the Republic of Pisa in negotiations with neighboring cities.
During the Renaissance period, the Lucidi name was also associated with the arts and intellectual pursuits. Andrea Lucidi (1495-1572), a scholar and humanist from Arezzo, was a renowned teacher and writer who authored several works on philosophy and rhetoric.
In the 18th century, the Lucidi surname gained further recognition through the achievements of Gian Domenico Lucidi (1708-1784), a celebrated architect and engineer from Rome. His most notable works include the design of several churches and palaces in the city, as well as the renovation of the ancient Roman aqueducts.
Throughout the centuries, the Lucidi name has been found in various parts of Italy, with notable concentrations in the regions of Tuscany, Lazio, and Umbria. While the spelling has remained relatively consistent, some variations such as Lucido and Lucida have also been recorded.

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 Lucidi surname at the time of the 2020 Census, not any inherent property of the name itself.
