Origin
Meaning and origin of Deluna
The surname DELUNA is believed to have originated in Spain, specifically in the region of Andalusia, during the time of the Moorish occupation in the 8th to 15th centuries. It is derived from the Spanish words "de" meaning "from" and "luna" meaning "moon," suggesting a connection to a place name or location associated with the moon.
One of the earliest recorded instances of the name DELUNA can be traced back to the 13th century in the city of Seville, where a family bearing this surname was mentioned in a local municipal record. It is also believed that the name may have been influenced by the Arabic word "al-qamar," meaning "the moon," as the Moors had a significant cultural impact on the Iberian Peninsula during their rule.
In the 14th century, a nobleman named Juan DELUNA was documented as a knight in the service of King Alfonso XI of Castile (1311-1350). He is mentioned in several chronicles from that period, including his participation in the Battle of Rio Salado in 1340, where he fought against the forces of the Marinid dynasty of Morocco.
During the 15th century, a prominent figure named Pedro DELUNA (c. 1420-1490) was a Catholic priest and scholar who played a significant role in the Spanish Inquisition. He served as an advisor to the monarchs Ferdinand II of Aragon and Isabella I of Castile, and was known for his expertise in theology and canon law.
In the 16th century, the DELUNA name can be found in records from the Spanish colonies in the Americas. One notable individual was Diego DELUNA (c. 1510-1575), an explorer and conquistador who participated in several expeditions to Florida and the Gulf Coast region of present-day United States. He is often credited with establishing some of the earliest Spanish settlements in that area.
Another prominent figure with the DELUNA surname was María DELUNA (1661-1734), a Spanish nun and mystic who lived in the 17th and 18th centuries. She was known for her spiritual writings and was beatified by the Catholic Church in 1891, being recognized for her exemplary life and virtues.
These are just a few examples of individuals with the surname DELUNA who have left their mark throughout history, illustrating the rich heritage and origins of this name rooted in the Iberian Peninsula and its cultural influences.

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 Deluna 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.
