Origin
The surname Larrazolo originated in Spain during the medieval period, specifically in the region of Navarre. It is believed to be derived from a Basque place name, likely a small village or hamlet, although the exact location is uncertain. The name itself may be a combination of the Basque words "larraz," meaning meadow or pasture, and "olo," which could signify a hill or mound.
One of the earliest recorded instances of the Larrazolo surname can be found in historical documents from the 14th century in Navarre. These records suggest that the name was initially associated with individuals who lived or worked in the vicinity of a particular meadow or pastureland.
In the 16th century, a notable figure named Juan de Larrazolo was mentioned in a manuscript detailing the Spanish conquest of the Americas. Juan de Larrazolo was a soldier who accompanied Hernán Cortés during the conquest of Mexico and is believed to have participated in the famous siege of Tenochtitlán in 1521.
Another prominent individual bearing the Larrazolo surname was Octaviano Ambrosio Larrazolo, born in 1859 in Chihuahua, Mexico. He was a lawyer, politician, and the 16th Governor of New Mexico, serving from 1919 to 1921. Octaviano Larrazolo played a significant role in advocating for the rights of Spanish-speaking residents in the region.
In the 19th century, a figure named José María Larrazolo made a notable contribution to the field of literature. Born in 1827 in Madrid, Spain, he was a renowned poet and playwright, known for his works that explored themes of love, nature, and Spanish culture.
During the 20th century, Aurelio Larrazolo, born in 1896 in Chihuahua, Mexico, gained recognition as a prominent educator and advocate for bilingual education. He dedicated his career to promoting the preservation of Spanish language and culture in the United States.
Another noteworthy individual with the Larrazolo surname was Ramón Larrazolo, born in 1888 in Chihuahua, Mexico. He was a celebrated artist and painter, whose works captured the vibrant landscapes and cultural traditions of his homeland, contributing to the development of Mexican art in the early 20th century.

The bar chart below shows how Larrazolo 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 Larrazolo surname at the time of the 2020 Census, not any inherent property of the name itself.
