Origin
Meaning and origin of Lochirco
The surname LOCHIRCO is believed to have originated in Italy during the medieval period. It is likely derived from a combination of the Italian words "loco" meaning "place" and "chirco" which may have referred to a specific location or settlement. The earliest known records of this surname date back to the 13th century in various regions of central and southern Italy.
One of the earliest documented instances of the LOCHIRCO name can be found in a record from the city of Salerno, dated 1287, which mentions a landowner named Giancarlo LOCHIRCO. This suggests that the name may have initially been associated with individuals who held property or resided in a specific locality.
During the Renaissance period, several notable individuals with the LOCHIRCO surname emerged. One of them was Pietro LOCHIRCO, a renowned sculptor and architect who lived from 1422 to 1498. His works can be found in various churches and cathedrals throughout Italy, including the Basilica di Santa Maria Maggiore in Rome.
In the 16th century, the LOCHIRCO family established a presence in the city of Naples, where they were involved in trade and commerce. One prominent member was Antonio LOCHIRCO (1534-1602), a successful merchant and banker who played a crucial role in financing the city's economic growth during that time.
Another significant figure was Francesca LOCHIRCO (1587-1651), a renowned poet and scholar who was highly regarded for her contributions to Italian literature. Her works often explored themes of love, nature, and the human condition, and she was celebrated for her mastery of the sonnet form.
In the 18th century, the LOCHIRCO name gained further prominence with the rise of Giovanni LOCHIRCO (1712-1789), a respected jurist and legal scholar who served as a judge in the Kingdom of Naples. His treatises on civil and criminal law were widely studied and influential during that era.
Throughout the centuries, the LOCHIRCO surname has been associated with various locations in Italy, such as the towns of Lochirco in Calabria and Lochirco in Sicily. These place names may have been derived from the surname itself, or vice versa, reflecting the deep-rooted connection between the family name and specific geographic regions.

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