Origin
Meaning and origin of Locurcio
The surname Locurcio originated in Italy, specifically in the southern regions of Campania and Calabria. It is believed to have emerged during the medieval period, sometime between the 11th and 13th centuries. Linguists trace the name's roots to the Latin word "locus," meaning "place" or "location," combined with the suffix "-urcio," which may have derived from a personal name or a variation of the Latin "curtius," meaning "short" or "small."
One of the earliest known references to the Locurcio name can be found in historical records from the town of Laureana di Borrello, a commune in the province of Reggio Calabria, where a family with this surname is documented as early as the 14th century. It is likely that the name originated in this region and later spread to other parts of southern Italy.
During the Renaissance period, the Locurcio name appeared in various church and municipal records, indicating its presence in different cities and towns across southern Italy. For instance, in the 16th century, a notable figure named Giovanni Locurcio (1520-1590) was a prominent scholar and professor of philosophy at the University of Naples.
Another individual of historical significance was Antonio Locurcio (1670-1745), a skilled architect and engineer from the city of Cosenza in Calabria. He is renowned for his contributions to the design and construction of several churches and public buildings in the region.
In the 18th century, a notable member of the Locurcio family was Vincenzo Locurcio (1735-1805), a highly respected jurist and legal scholar from the town of Laureana di Borrello. His works on civil law and jurisprudence were widely studied and cited during his time.
Over the centuries, the Locurcio surname has also been associated with various locations and place names, such as the village of Locurci in the province of Catanzaro, Calabria, which may have influenced the spelling and pronunciation of the name in certain areas.
Another prominent figure bearing the Locurcio surname was Giuseppe Locurcio (1880-1956), a celebrated painter and artist from the city of Naples. His works, which often depicted scenes of everyday life in Naples, were widely acclaimed and exhibited in galleries across Italy.

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.

Keep in mind that these are self-reported numbers.
