Origin
Meaning and origin of Mansanares
The surname Mansanares originates from Spain, first appearing in historical records during the medieval period. It is believed to derive from the Spanish place name "Manzanares," which itself comes from the Mozarabic Arabic term "manğan-nar," meaning "water reservoir" or "water ditch."
The earliest known documented use of the surname Mansanares can be traced back to the 13th century in the region of La Mancha, located in central Spain. This area was once a frontier between Christian and Moorish territories, and the name likely arose as a toponymic surname, indicating a person's place of origin or residence near the Manzanares River.
In the 15th century, a notable figure named Juan Mansanares was recorded as serving as a royal scribe for King Juan II of Castile. Another individual, Diego Mansanares, was a renowned cartographer and navigator who accompanied Christopher Columbus on his second voyage to the Americas in 1493.
During the 16th century, the Mansanares surname appeared in various Spanish colonial records, indicating that individuals bearing this name had participated in the exploration and settlement of the Spanish territories across the Atlantic. One such example is Pedro Mansanares, a conquistador who was involved in the conquest of Peru under Francisco Pizarro in the 1530s.
In the 17th century, a prominent figure was Sebastián Mansanares, a Spanish playwright and poet who lived in Madrid and contributed to the Golden Age of Spanish literature. His works included several comedies and religious plays.
Another notable individual was María Mansanares, a 19th-century Spanish painter and artist known for her portraits and genre scenes depicting everyday life in Spain. She was born in Valencia in 1815 and her works were exhibited at various salons and exhibitions during her lifetime.
While the Mansanares surname has its roots in Spain, it has since spread to other regions through migration and diaspora, with individuals bearing this name found in various parts of the world, including Latin America and some Spanish-speaking communities in the United States.

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