The surname Delarosa is a Spanish surname that originated in Spain during the medieval period. It is a locational surname, derived from the Spanish phrase "de la rosa," which means "of the rose." This suggests that the name may have originally referred to someone who lived near a rose bush or garden.
The earliest recorded instance of the surname Delarosa dates back to the 13th century in the region of Castile, Spain. It is believed that the name may have been associated with a particular place or location, possibly a town or village with the word "rosa" in its name.
In the 15th century, the surname Delarosa appeared in historical records related to the Spanish conquest of the Americas. One notable figure was Juan Delarosa, a Spanish explorer and conquistador who participated in the conquest of Mexico alongside Hernán Cortés in the early 16th century.
During the 16th and 17th centuries, the Delarosa surname spread throughout Spain and its colonies in the Americas. In the 18th century, a prominent figure named María Delarosa (1702-1789) was a renowned Spanish poet and writer who gained recognition for her literary works.
In the 19th century, the Delarosa surname was found in various parts of Latin America, particularly in Mexico, where it became a prominent surname. One notable individual was Ignacio Delarosa (1823-1901), a Mexican politician and military officer who played a significant role in the Reform War and the French Intervention in Mexico.
Another notable figure with the Delarosa surname was Pedro Delarosa (1876-1942), a Cuban writer and journalist who was known for his contributions to the literary movement of the early 20th century in Cuba.

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 Delarosa 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.
