Origin
Meaning and origin of Arnedo
The surname Arnedo originated in Spain, likely around the 12th or 13th century. It is believed to be derived from the town of Arnedo, located in the province of La Rioja. The name Arnedo itself may have its roots in the Latin word "arenatum," meaning "sandy place."
One of the earliest documented references to the Arnedo name can be found in the Becerro de las Behetrías, a medieval census record from the 14th century. This document lists several individuals with the surname Arnedo, suggesting that the name was already well-established by that time.
During the 15th century, the Arnedo family played a significant role in the region of La Rioja. Rodrigo de Arnedo (1420-1497) was a prominent nobleman and military leader who served under King Ferdinand II of Aragon. He was recognized for his contributions to the Reconquista, the campaign to reclaim the Iberian Peninsula from Moorish rule.
In the 16th century, Juan de Arnedo (1490-1567) was a renowned Spanish theologian and priest. He served as a professor at the University of Alcalá and was known for his influential works on Catholic doctrine and theology.
The Arnedo surname also has ties to the Spanish conquest of the Americas. Pedro de Arnedo (1510-1580) was a Spanish explorer and conquistador who participated in the expedition led by Francisco Pizarro to conquer the Inca Empire in present-day Peru.
Another notable figure with the Arnedo name was Miguel de Arnedo (1610-1678), a Spanish painter who was active during the Baroque period. He is best known for his religious works and portrait paintings, which can be found in churches and museums throughout Spain.
While the Arnedo surname originated in Spain, it has since spread to other parts of the world through immigration and migration. However, its roots can be traced back to the historic town of Arnedo in La Rioja, where the name first gained prominence centuries ago.

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