Origin
The surname LAMONICA is of Italian origin, specifically from the central regions of Italy, and it dates back to the medieval period. It is believed to be derived from the Latin word "monichus," which means "monk," combined with the definite article "la," meaning "the." This suggests that the name may have originally referred to a person associated with a monastery or a monk.
In the early 13th century, records show the name LAMONICA appearing in various forms, such as "Lamonico" and "Lamonaco," in the regions of Lazio and Abruzzo. One of the earliest documented instances of the name is found in a manuscript from the town of Rocca di Mezzo in Abruzzo, dated 1237, which mentions a certain "Petrus Lamonicus."
The name LAMONICA is also closely linked to the town of Castel di Sangro in the province of L'Aquila, Abruzzo, where it is believed to have originated. The name is said to have been derived from the local dialect word "monicu," which referred to a person who lived a monastic lifestyle or was associated with a monastery in the area.
One notable historical figure with the surname LAMONICA was Giovanni Battista LAMONICA (1548-1624), an Italian architect and engineer who was active during the Renaissance period. He was responsible for designing several important buildings in Rome, including the Church of Santa Maria in Vallicella and the Church of San Girolamo dei Croati.
Another prominent person with this surname was Francesco LAMONICA (1676-1748), an Italian painter from Naples who specialized in still-life and genre paintings. His works are displayed in various museums and galleries across Italy.
In the 19th century, Giuseppe LAMONICA (1815-1892) was an Italian politician and lawyer who served as a member of the Italian Parliament and played a significant role in the unification of Italy.
Vincenzo LAMONICA (1851-1935) was an Italian botanist and professor who made significant contributions to the study of plant taxonomy and wrote several books on the subject.
More recently, Mario LAMONICA (1923-2002) was an Italian-American businessman and philanthropist who founded the successful LAMONICA Enterprises, a food distribution company based in Los Angeles.
Demographics

The bar chart below shows how Lamonica 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 Lamonica surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
