Origin
Meaning and origin of Ottoboni
The surname Ottoboni originates from Italy, with its earliest known roots dating back to the 13th century in the city of Rome. The name is believed to be derived from the Italian words "otto" meaning "eight" and "boni" meaning "good" or "virtuous," suggesting a possible connection to an eighth child or the fulfillment of a good quality.
Historical records indicate that the Ottoboni family was a prominent and influential noble family in Rome during the Middle Ages and Renaissance periods. One of the earliest documented mentions of the name appears in a 14th-century manuscript, where a certain Pietro Ottoboni is listed as a prominent citizen and landowner in the city.
In the 17th century, Cardinal Pietro Vito Ottoboni (1610-1691) was a notable figure who served as the Dean of the College of Cardinals and became a patron of the arts, sponsoring composers such as Arcangelo Corelli and Alessandro Scarlatti. His nephew, Pietro Ottoboni (1667-1740), also held the position of Cardinal and was an accomplished scholar and art collector.
Another prominent individual with the surname Ottoboni was Flavio Ottoboni (1524-1590), who served as the Bishop of Arezzo in Tuscany during the late 16th century. His ecclesiastical writings and contributions to the Catholic Church earned him a reputation as a respected theologian and reformer of his time.
In the realm of arts and culture, the name Ottoboni is associated with the influential Ottoboni family of Rome, who were renowned patrons of music and the arts during the Baroque period. Their patronage supported the works of numerous renowned composers, painters, and artists, leaving a lasting impact on the cultural landscape of Italy.
Other notable figures with the surname Ottoboni include Giovanni Ottoboni (1643-1692), a Venetian diplomat and ambassador to the Holy Roman Empire, and Marcantonio Ottoboni (1737-1827), an Italian architect and urban planner who designed several prominent buildings in Rome and its surroundings.

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