Origin
Meaning and origin of Camastro
The surname CAMASTRO has its origins in Italy, with the earliest records dating back to the 12th century in the regions of Campania and Basilicata. The name is believed to be derived from the Latin word "camastra," which referred to a type of rural dwelling or farmhouse. This suggests that the surname may have been initially associated with those who lived in or worked on such properties.
In the 13th century, there are references to the name CAMASTRO in several historical documents, including land ownership records and tax rolls. One notable early bearer of the name was Giovanni Camastro, a landowner from the town of Potenza in Basilicata, who was mentioned in a legal document from 1259.
As the name spread across Italy, different variations in spelling emerged, including Camastri, Camastra, and Camastri. These variations were often influenced by regional dialects and local pronunciation patterns.
During the Renaissance period, the CAMASTRO surname gained some prominence in the arts and academia. Francesco Camastro (1510-1587), a renowned painter from Naples, is known for his contributions to the Mannerist style of painting. His works can be found in several churches and galleries across Italy.
In the 18th century, Giuseppe Camastro (1740-1815) was a respected scholar and philosopher from Calabria. His writings on ethics and political theory were widely studied and discussed in academic circles of the time.
As Italian immigrants began to settle in other parts of the world, the CAMASTRO surname traveled with them. In the late 19th century, Antonio Camastro (1857-1932) was among the first Italians to establish a successful winemaking business in California's Napa Valley.
Throughout the 20th century, several notable individuals bore the CAMASTRO surname, including Mario Camastro (1908-1998), a celebrated Italian opera singer who performed in major venues across Europe and the United States, and Maria Camastro (1925-2010), a renowned sculptor whose works are featured in public spaces and museums in Italy and abroad.

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