Origin
The surname LACORAZZA is of Italian origin, originating in the regions of Campania and Calabria during the Middle Ages. It is derived from the Italian words "la corazza," meaning "the armor" or "the breastplate." This suggests that the surname may have been initially bestowed upon an individual who was a skilled armorer or someone who wore distinctive armor.
In historical records, the earliest known reference to the surname LACORAZZA can be traced back to a document from the year 1327 in the town of Salerno, located in the Campania region. This document mentions a certain Giovanni LACORAZZA, who was a local blacksmith and armorer.
During the 15th century, the surname LACORAZZA appeared in several municipal records from the city of Cosenza, in the Calabria region. One notable example is the record of a nobleman named Pietrantonio LACORAZZA, who was a member of the local nobility and served as a councilor in the city's government in the year 1482.
In the 16th century, the name LACORAZZA was also found in records from the town of Vallo della Lucania, in the province of Salerno. A notable figure from this period was Gianpaolo LACORAZZA, a respected physician and scholar who lived between 1524 and 1598.
Another notable individual bearing the surname LACORAZZA was Vincenzo LACORAZZA, a military commander who served in the armies of the Kingdom of Naples during the 17th century. He was born in 1621 in the town of Campagna, in the province of Salerno, and distinguished himself in several battles against foreign invaders.
In the 18th century, the surname LACORAZZA was also found in records from the city of Naples itself. One notable individual was Domenico LACORAZZA, a prominent lawyer and legal scholar who lived from 1735 to 1812. He authored several influential works on legal principles and served as a judge in the Neapolitan court system.
Throughout its history, the surname LACORAZZA has been associated with various geographical locations within the regions of Campania and Calabria, such as the towns of Salerno, Cosenza, Vallo della Lucania, Campagna, and the city of Naples itself. The name has also been subject to slight variations in spelling, including LACORAZA and LACORRAZZA, but the core meaning and origin have remained consistent.
Demographics
Among Census respondents with the surname Lacorazza, the largest self-reported group is White at 87.4%. The next largest groups are Hispanic (12.6%).
The bar chart below shows how Lacorazza 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 Lacorazza surname at the time of the 2020 Census, not any inherent property of the name itself.
