Origin
Meaning and origin of Maiuro
The surname "Maiuro" is believed to have its origins in Italy, specifically in the regions of Campania and Calabria. It is thought to be derived from the Latin word "maior," which means "greater" or "larger." This suggests that the name may have been initially given to someone who possessed a quality or characteristic that was considered greater or larger than others.
One of the earliest recorded instances of the name "Maiuro" can be found in the historical records of the Kingdom of Naples, dating back to the 15th century. During this period, the name was often spelled as "Maiore" or "Maiori," which further solidifies its connection to the Latin word "maior."
In the late 16th century, a notable figure named Giovanni Battista Maiuro (1550-1624) was a prominent lawyer and jurist in the city of Naples. His legal expertise and contributions to the local judicial system earned him a respected reputation during his lifetime.
Another historical figure bearing the surname "Maiuro" was Pietro Maiuro (1620-1688), a renowned painter from the city of Cosenza in Calabria. His works, predominantly religious in nature, adorned many churches and monasteries throughout the region, showcasing his artistic talents.
During the 18th century, the name "Maiuro" was also found in the records of the Papal States, specifically in the area around Rome. One notable mention is that of Francesco Maiuro (1715-1789), a respected clergyman who served as a papal diplomat and held influential positions within the Catholic Church hierarchy.
In the 19th century, Antonio Maiuro (1810-1884) was a prominent landowner and entrepreneur from the town of Caserta, near Naples. His successful business ventures and philanthropic endeavors made him a well-respected figure in the local community.
Interestingly, the name "Maiuro" can also be traced back to certain place names in Italy, such as the town of Maiori on the Amalfi Coast, which further reinforces the potential connection between the surname and the Latin word "maior."

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