Origin
Meaning and origin of Larosa
The surname Larosa has its origins in Italy, where it emerged during the medieval period, likely in the 12th or 13th century. It is derived from the Italian phrase "la rosa," which translates to "the rose." This name may have initially been a descriptive nickname referring to someone associated with roses, perhaps a rose cultivator or a person who lived near a rosebush.
One of the earliest recorded instances of the Larosa name can be found in the Codice Diplomatico Padovano, a collection of historical documents from the city of Padua, dated around 1250. This suggests that the name was already well-established in northern Italy by the 13th century.
In the 14th century, the Larosa surname appeared in various records from the Republic of Venice, particularly in the city of Verona. One notable figure was Bartolomeo Larosa, a merchant and diplomat who lived from 1325 to 1390. He was involved in trade negotiations with other Italian city-states and played a role in strengthening Verona's economic ties.
As the surname spread throughout Italy, variations in spelling emerged, including LaRosa, La Rosa, and De Rosa. These variations often reflected regional dialects and local pronunciation patterns. In the 16th century, a prominent member of the Larosa family was Girolamo Larosa, a Renaissance scholar and humanist born in Naples in 1505. He was renowned for his literary works and contributions to the study of classical Greek and Latin texts.
During the 17th century, the Larosa name gained prominence in Sicily, where several members of the family held influential positions in the local nobility. Vincenzo Larosa, born in 1620 in Palermo, was a celebrated poet and playwright who wrote numerous works in the Sicilian dialect.
As Italians began to emigrate to other parts of the world in the late 19th and early 20th centuries, the Larosa surname spread to new regions. One notable figure was Salvatore Larosa, an Italian-American artist born in 1890 in New York City. He became known for his vibrant paintings depicting scenes of Italian-American life in the early 20th century.
While the origins of the Larosa surname can be traced back to medieval Italy, it has since become a widespread name found in various parts of the world, reflecting the global reach of Italian migration and cultural influence.

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

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Larosa (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
