Origin
Meaning and origin of Quirico
The surname Quirico has its origins in Italy, dating back to the 12th century. It is derived from the Latin name Quiricus, which was a personal name given to children in ancient Rome. The name itself is believed to have originated from the word "quiris," meaning a Roman citizen.
In the early days, the surname Quirico was predominantly found in the regions of Tuscany and Lazio, particularly in the cities of Florence and Rome. It is believed that the name first appeared in historical records during the 13th century, when surnames started becoming more common among the Italian population.
One of the earliest recorded instances of the surname Quirico can be found in the Florentine tax records of 1297, where a certain Niccolò Quirico is mentioned. Another early reference is in the Codice Diplomatico Dantesco, a collection of documents related to the life of the famous Italian poet Dante Alighieri, which mentions a Quirico di Fiorino in the year 1321.
In the 14th century, the name Quirico was also found in other parts of Italy, such as Lombardy and Emilia-Romagna. During this time, variations of the spelling emerged, including Quirici, Quirici, and Quirico.
One of the notable individuals bearing the surname Quirico was Domenico Quirico, a renowned painter from the city of Siena, who lived between 1492 and 1554. His works can be found in various churches and galleries throughout Italy.
Another notable figure was Vincenzo Quirico, a lawyer and politician from Naples, who lived from 1650 to 1728. He served as a judge in the Supreme Court of Naples and was known for his expertise in civil and canon law.
In the 18th century, the surname Quirico gained prominence in the field of literature with the birth of Gaetano Quirico (1746-1818), a playwright and poet from the city of Palermo. His works were widely acclaimed and performed in theaters across Italy.
Moving into the 19th century, we find Francesco Quirico (1818-1892), a renowned architect from Rome. He was responsible for designing several notable buildings, including the Church of San Giuseppe in Palermo and the Palazzo delle Esposizioni in Rome.
Lastly, in the 20th century, there was Quirico Filopanti (1912-1985), an Italian politician and member of the Christian Democratic Party. He served as a member of the Italian Parliament and was known for his work in promoting social welfare policies.

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

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
