Origin
Meaning and origin of Berriochoa
The surname BERRIOCHOA originated in the Basque region of northern Spain and southwestern France, an area known for its unique language and culture. The name itself is derived from the Basque words "berri" meaning "new" and "etxe" meaning "house" or "home," suggesting that the name was likely given to someone who had built or moved into a new house or settlement.
One of the earliest recorded instances of the name BERRIOCHOA can be found in the Cartulario de San Millán de la Cogolla, a medieval manuscript dating back to the 11th century. This cartulary, which contains records of land transactions and legal documents, mentions individuals with the surname BERRIOCHOA in the village of Ezcaray, located in the province of La Rioja, Spain.
In the 13th century, a man named Juan BERRIOCHOA was recorded as a landowner in the town of Vitoria-Gasteiz, the capital of the Basque Country. This suggests that the BERRIOCHOA family had established themselves as prominent members of the local community.
During the 16th century, the BERRIOCHOA name appeared in various records throughout the Basque region, including the Archivo General de Navarra (General Archive of Navarre). One notable individual from this time period was María BERRIOCHOA, who was born in 1543 in the village of Lekunberri, Navarre.
In the 17th century, a man named Pedro BERRIOCHOA served as a soldier in the Spanish Army during the Thirty Years' War (1618-1648). His military exploits and service to the crown were recorded in the archives of the Kingdom of Spain.
Another notable figure bearing the BERRIOCHOA surname was Sebastián BERRIOCHOA, a Basque writer and poet who lived in the late 18th century. He is best known for his work "Euskal Herriko Olerki Zaharrak" (Old Basque Poems), which helped preserve and promote the Basque language and culture.
As the BERRIOCHOA family spread throughout the Basque region and beyond, variations in the spelling of the name emerged, including Berriochoa, Berriochua, and Berriochue. Additionally, some individuals with the surname adopted place names as part of their full name, such as BERRIOCHOA de Ezcaray or BERRIOCHOA de Vitoria.

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