Origin
Meaning and origin of Vallillo
The surname Vallillo has its origins in Italy, originating in the 14th century. It is believed to be derived from the Italian word "valle," meaning valley, and the suffix "-illo," which is a diminutive form indicating "little." This suggests that the name may have initially referred to someone who lived in a small valley or a person from a specific location known as "Vallillo."
One of the earliest recorded instances of the name Vallillo can be found in the Italian archives from the early Renaissance period. A document dated 1432 mentions a certain "Giovanni Vallillo," a merchant from the city of Genoa. This provides evidence of the name's existence and usage during that era.
In the late 15th century, a notable figure with the surname Vallillo emerged. Antonio Vallillo (1456-1531) was a renowned Italian architect and engineer who contributed to the design and construction of several notable buildings and fortifications in various Italian cities, including Rome and Naples.
Moving forward to the 17th century, the name Vallillo appears in the birth records of a small village near Salerno, Southern Italy. In 1623, a child named Matteo Vallillo was born to a family of farmers in this region, suggesting the surname's continued presence in the area.
During the 18th century, a painter named Giuseppe Vallillo (1718-1788) gained recognition for his religious and mythological works. His paintings can still be found in various churches and galleries across Italy, particularly in the regions of Campania and Lazio.
Another notable figure with the surname Vallillo was Antonio Vallillo (1789-1862), a Italian composer and music teacher who lived during the late 18th and early 19th centuries. He is credited with composing several operas and sacred works that were performed in various theaters and churches throughout Italy.
Throughout its history, the surname Vallillo has maintained a strong presence in various regions of Italy, particularly in the southern and central parts of the country. While not widespread, it has been carried by individuals from diverse backgrounds, including merchants, artists, architects, and musicians, contributing to the rich cultural tapestry of Italian society.

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