Origin
Meaning and origin of Robilotta
The surname Robilotta is believed to have originated in Italy, likely during the medieval period. It is thought to be derived from the Italian word "robillotto," which means a small oak tree or shrub. This suggests that the name may have initially been given to someone who lived near or was associated with such vegetation.
One of the earliest known records of the name appears in a document from the 14th century, where a person named Giovanni Robilotta is mentioned as a landowner in the region of Calabria, located in southern Italy. This indicates that the name had already become established in that area by that time.
In the 15th century, there are references to a family by the name of Robilotta residing in the city of Naples. Historical records show that they were involved in the local government and held positions of influence within the community.
During the 16th century, a notable figure named Antonio Robilotta (1522-1592) gained recognition as a skilled architect and engineer. He was responsible for designing several notable buildings and structures in Naples and its surrounding areas.
Another individual of note was Giancarlo Robilotta (1675-1741), a renowned painter from the city of Cosenza in Calabria. His works, primarily religious in nature, were highly regarded during his lifetime and can still be found in various churches and galleries throughout Italy.
In the 18th century, a prominent lawyer and legal scholar named Giuseppe Robilotta (1712-1795) made significant contributions to the field of jurisprudence. His writings and interpretations of law were widely studied and influential in shaping legal practices of the time.
Over the centuries, variations in the spelling of the name have emerged, including Robiglotta, Rovilotta, and Robilotta. These variations are often associated with different regions or local dialects within Italy.
While the surname Robilotta is not among the most common in Italy today, it has a rich history and can be traced back to its origins in the medieval period, where it was likely derived from a connection to oak vegetation in the southern regions of the country.

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

Does the Census include every surname?
