Origin
Meaning and origin of Dinaro
The surname Dinaro originates from Italy, specifically from the region of Sicily. It is believed to have emerged in the 13th or 14th century, during the period when the island was under the rule of the Crown of Aragon.
The name is derived from the Italian word "denaro," which means "money" or "coin." This suggests that the original bearer of the surname may have been a moneylender, a banker, or someone involved in some form of financial or monetary profession.
One of the earliest recorded instances of the name Dinaro can be found in a document from the city of Palermo, dated 1376. This document mentions a certain "Giovanni Dinaro," who is described as a merchant and landowner.
The surname Dinaro has also been associated with several notable individuals throughout history. One such figure is Vincenzo Dinaro (1720-1795), a Sicilian architect who designed several churches and palaces in the Baroque style, including the Church of Santa Maria della Pietà in Palermo.
Another prominent bearer of the name was Gaetano Dinaro (1839-1916), an Italian botanist and professor at the University of Palermo. He made significant contributions to the study of Sicilian flora and published several works on the subject.
In the 16th century, the name Dinaro appears in records from the town of Militello in Val di Catania, where a family of that name owned several estates and vineyards. One member of this family, Francesco Dinaro (1542-1612), was a renowned winemaker and is credited with developing a particular method of aging and blending wines that became popular in the region.
In the 18th century, the Dinaro surname can be found in documents from the town of Acireale, near Catania. Here, a family of that name was involved in the production and export of citrus fruits, particularly lemons, which were a major agricultural product of the area at the time.
Another notable figure bearing the Dinaro surname was Giuseppe Dinaro (1876-1944), an Italian painter and sculptor from Palermo. He is known for his works depicting scenes of everyday life in Sicily, as well as his sculptures of religious subjects.
While the surname Dinaro is not as common today as it once was, it remains a part of the rich cultural heritage of Sicily and serves as a reminder of the island's longstanding ties to commerce, agriculture, and the arts.

The bar chart below shows how Dinaro bearers described their own race and ethnicity on the 2020 Census form. 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 Dinaro surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
