Origin
The surname CUCULLU has its origins in Italy, dating back to the late medieval period. It is believed to have derived from the Latin word "cucullus," which means "hood" or "cowl," referring to the hooded garments worn by monks.
The name was likely first adopted by individuals who lived near monasteries or had some association with monastic orders. It may have been a nickname or a descriptive term for someone who worked or lived in proximity to monks or was known for wearing a similar hooded garment.
One of the earliest recorded instances of the name CUCULLU can be found in the archives of the Benedictine monastery of Monte Cassino, located in the region of Campania, Italy. A document from the 13th century mentions a certain Frater Cucullu, a monk residing at the monastery.
In the 14th century, the name appears in various municipal records from the city of Naples, suggesting that the CUCULLU family had established roots in the area. One notable reference is the mention of Giacomo CUCULLU, a merchant who owned several properties in the city's historic center in the mid-1300s.
As the name spread throughout Italy, it underwent slight variations in spelling, such as CUCCULLU, CUCULLUS, and CUCCULO. These variations were likely influenced by regional dialects and the preferences of local scribes.
In the 15th century, the CUCULLU name gained prominence in the Republic of Venice, where a branch of the family settled. One of the most notable figures from this period was Marco CUCULLU, a successful merchant and diplomat who served as the Venetian consul in Constantinople (modern-day Istanbul) from 1456 to 1463.
Another significant figure bearing the CUCULLU name was Girolamo CUCULLU, a renowned philosopher and humanist who lived in the 16th century. Born in Naples in 1508, Girolamo was a prolific writer and scholar, known for his works on philosophy, literature, and theology.
In the 17th century, the CUCULLU family had a presence in the Papal States, particularly in the city of Rome. One member of note was Cardinal Pietro CUCULLU, who served as a high-ranking official in the Catholic Church and played a influential role in the Vatican during the pontificate of Pope Innocent XI in the late 1600s.
Throughout its history, the CUCULLU surname has been associated with various professions, including clergy, merchants, scholars, and diplomats. While the name may have originated from a humble nickname, it has left a lasting mark on the cultural and intellectual fabric of Italy.
Demographics
Among Census respondents with the surname Cucullu, the largest self-reported group is White at 71.8%. The next largest groups are Hispanic (22.2%) and Two or More Races (2.6%).
The bar chart below shows how Cucullu 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 Cucullu surname at the time of the 2020 Census, not any inherent property of the name itself.
