Origin
The surname DELLAVENTURA has its origins in Italy, specifically in the regions of Veneto and Lombardy. It is believed to have emerged during the 13th or 14th century, deriving from the Italian phrase "della ventura," which translates to "of fortune" or "of luck."
This surname is thought to have been initially adopted by individuals who lived near a location associated with good fortune or prosperity. It could also have been a descriptive name given to someone who was considered fortunate or lucky. The name's earliest documented appearance can be traced back to the late 14th century, with records mentioning a Nicolo Dellaventura residing in the city of Verona.
In the 15th century, the name appears in various historical documents, including tax records and legal proceedings in the Veneto region. One notable bearer was Francesco Dellaventura, a merchant from Venice who lived between 1430 and 1492.
During the Renaissance period, the surname gained prominence in the arts and literature. Giovanni Dellaventura, born in 1521 in Padua, was a renowned painter renowned for his religious frescoes adorning numerous churches in northern Italy.
As the name spread throughout the Italian peninsula, regional variations in spelling emerged, such as Dellaventura, Della Ventura, and Ventura. In the 17th century, Pietro Della Ventura (1592-1667), a scholar from Naples, made significant contributions to the field of philosophy and theology.
The 19th century saw the name gain international recognition with the exploits of Gaetano Dellaventura (1801-1875), an Italian explorer and cartographer who mapped vast regions of South America, particularly in present-day Brazil and Argentina.
While the surname DELLAVENTURA is predominantly found in Italy, it has also been carried to other parts of the world by Italian emigrants. Notable bearers include Francesco Dellaventura (1887-1967), an Italian-American opera singer, and Emilio Dellaventura (1915-2008), an Italian-Canadian artist renowned for his landscapes and portraits.
Demographics
Among Census respondents with the surname Dellaventura, the largest self-reported group is White at 89.1%. The next largest groups are Hispanic (8.2%) and Two or More Races (1.8%).
The bar chart below shows how Dellaventura 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 Dellaventura 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.
