Origin
Meaning and origin of Delariva
The surname DELARIVA originated in Spain during the medieval period. It is a locational name, derived from the Spanish phrase "de la riva", meaning "from the riverbank". This suggests that the earliest bearers of this name lived near a prominent river or waterway.
DELARIVA can be traced back to the 12th century in the regions of Andalusia and Extremadura in southern Spain. Historical records from this period show variations in spelling, such as De la Riba, De la Ribera, and Delaribera, which all refer to the same locational origin.
One of the earliest known references to the DELARIVA name appears in the Libro de la Montería, a hunting treatise commissioned by King Alfonso XI of Castile in the 14th century. The text mentions a nobleman named Rodrigo Delariva, who was part of the royal hunting party.
In the 15th century, a prominent figure with this surname was Pedro Delariva, a Spanish explorer and navigator who accompanied Christopher Columbus on his second voyage to the Americas in 1493. Pedro Delariva played a crucial role in establishing settlements in the Caribbean islands.
During the 16th century, the DELARIVA name gained recognition through the works of the poet and playwright, Juan Delariva (c. 1520–1580). He was celebrated in his time for his contributions to the development of Spanish Renaissance literature.
Another notable bearer of this surname was María Delariva (1602–1676), a Spanish nun and mystic who founded the Order of the Immaculate Conception. Her writings on spiritual matters were influential in the Catholic Church during the 17th century.
In the 18th century, the DELARIVA name was associated with the Spanish artist Francisco Delariva (1734–1795), known for his portraits and religious paintings. His works can be found in several churches and museums across Spain.
The DELARIVA surname has a rich historical legacy, with its origins rooted in the vibrant culture and traditions of medieval Spain. Its bearers have left their mark across various fields, from exploration and literature to religion and art, contributing to the cultural tapestry of the Spanish-speaking world.

The bar chart below shows how Delariva 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 Delariva surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Delariva (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
