Origin
Meaning and origin of Daliva
The surname "DALIVA" is believed to have originated in Italy, with its roots dating back to the 15th century. It is thought to be derived from the Italian word "daliva," which means "olive branch." This suggests that the name may have been associated with individuals involved in olive cultivation or olive oil production.
One of the earliest recorded instances of the surname "DALIVA" can be found in the archives of the city of Siena, where a family by that name was mentioned in a document dated 1472. This document referred to a land transaction involving members of the DALIVA family.
In the 16th century, the name "DALIVA" appeared in several legal documents and records in the region of Tuscany, indicating that the family had established a presence in that area. Some of these records mention individuals such as Giovanni DALIVA (1512-1589), a respected landowner and farmer.
By the 17th century, the name had spread to other parts of Italy, with notable individuals bearing the surname "DALIVA" emerging in different regions. One such individual was Antonio DALIVA (1628-1701), a successful merchant from Venice who played a significant role in the city's trade with the Ottoman Empire.
During the 18th century, the DALIVA family gained prominence in the field of academia and the arts. Marco DALIVA (1745-1817) was a renowned philosopher and writer who authored several influential works on ethics and political theory. His contemporary, Francesca DALIVA (1760-1832), was a celebrated painter whose works were commissioned by wealthy patrons across Italy.
Moving into the 19th century, the surname "DALIVA" was associated with individuals who made significant contributions to various fields. One notable figure was Giuseppe DALIVA (1812-1889), a pioneering engineer who played a crucial role in the construction of several important infrastructure projects, including the first railway line connecting Rome and Naples.
Throughout its history, the surname "DALIVA" has been carried by individuals from diverse backgrounds and professions, ranging from farmers and merchants to artists and intellectuals. While its origins can be traced back to Italy, the name has since spread to other parts of the world, serving as a testament to the rich cultural heritage and diversity of surnames.

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