Origin
The surname Mendosa originated in Spain during the medieval period. It is believed to have derived from the Spanish word "mendoza," which means a bramble bush or a place abundant with such bushes. The name was likely initially a toponymic surname, referring to someone who lived near or came from a location with an abundance of bramble bushes.
One of the earliest recorded instances of the surname Mendosa can be found in the Cartulario de San Millán de la Cogolla, a medieval manuscript dating back to the 11th century. This document mentions several individuals bearing the name, indicating its presence in Spain during that time.
The Mendosa family was influential in Spain during the Middle Ages and the Renaissance period. Íñigo López de Mendoza, also known as the Marqués de Santillana (1398-1458), was a prominent Spanish poet, nobleman, and patron of the arts. He played a significant role in the development of Spanish literature and the promotion of Renaissance humanism in Spain.
Another notable figure was Pedro González de Mendoza (1428-1495), a Spanish cardinal and statesman who served as the Archbishop of Seville and the Grand Cardinal of Spain. He was instrumental in the Spanish Inquisition and played a crucial role in the expulsion of Jews and Muslims from Spain.
During the colonial era, the surname Mendosa spread to the Americas as Spanish settlers and conquistadors carried the name to the New World. One example is Antonio de Mendoza (1490-1552), a Spanish nobleman who served as the first Viceroy of New Spain (present-day Mexico) from 1535 to 1550.
In the realm of literature, the surname Mendosa is associated with Diego Hurtado de Mendoza (1503-1575), a Spanish novelist, poet, and diplomat known for his picaresque novel "Lazarillo de Tormes," considered one of the earliest examples of the genre.
The name Mendosa has also been associated with various places and locations throughout Spain. For instance, the town of Mendoza in the province of Álava and the Mendoza district in the city of Vitoria-Gasteiz both derive their names from the surname.
Demographics
Among Census respondents with the surname Mendosa, the largest self-reported group is Hispanic at 88.5%. The next largest groups are White (7.6%) and Asian/Pacific Islander (1.8%).
The bar chart below shows how Mendosa 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 Mendosa surname at the time of the 2020 Census, not any inherent property of the name itself.
