Origin
Meaning and origin of Delvillar
The surname DELVILLAR is of Spanish origin, dating back to the medieval period in the regions of Castile and Aragon. It is derived from the Spanish words "del" meaning "of" or "from," and "villar," which refers to a small village or hamlet.
The earliest recorded instances of the surname can be traced back to the 13th century in various historical documents and records from the kingdoms of Castile and Aragon. The name likely originated as a way to identify individuals who hailed from a particular small village or settlement, distinguishing them from others who shared the same given name.
One notable historical reference to the surname DELVILLAR is found in the "Libro de la Montería" (Book of the Hunt), written in the 14th century during the reign of King Alfonso XI of Castile. This text, which detailed hunting practices and territories, mentioned several individuals bearing the DELVILLAR surname, suggesting their connection to rural areas and possibly involvement in hunting activities.
In the 15th century, records from the city of Seville mention a prominent figure named Juan Delvillar, who served as a respected merchant and city councilor. His influence and wealth were indicative of the social mobility and prominence achieved by some members of the DELVILLAR family during that period.
The 16th century saw the birth of Rodrigo Delvillar (1523-1586), a notable Spanish explorer and navigator who accompanied various expeditions to the New World. His contributions to the exploration and mapping of the Americas further added to the historical significance of the DELVILLAR name.
Another individual of note was María Delvillar (1677-1743), a renowned painter and portraitist from the city of Valencia. Her works, which adorned numerous churches and private collections, were highly regarded for their artistic merits and attention to detail.
In the 18th century, the DELVILLAR surname gained prominence in the field of literature with the birth of Miguel Delvillar (1745-1819), a celebrated Spanish playwright and poet. His contributions to the Spanish Golden Age of literature were widely recognized and celebrated during his lifetime.
Throughout its history, the DELVILLAR surname has been associated with various professions, from merchants and explorers to artists and writers, reflecting the diverse backgrounds and achievements of those who bore this name across different regions of Spain.

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

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.
