Origin
The surname Otamendi is of Spanish origin, specifically tracing its roots to the Basque region of northern Spain and southern France. It is believed to have originated in the late medieval period, around the 14th or 15th century.
The name Otamendi is derived from a combination of the Basque words "ota" meaning "foothill" or "low hill" and "mendi" meaning "mountain." This suggests that the name likely referred to a person or family residing in a mountainous area near foothills or lower elevations.
One of the earliest recorded mentions of the Otamendi surname can be found in the archives of the town of Vitoria-Gasteiz, the capital of the Basque Country, dating back to the late 15th century. It is documented that an individual named Juan de Otamendi was a prominent landowner and merchant in the region during that time.
In the 16th century, the Otamendi name appears in records related to the Spanish conquest and colonization of the Americas. Pedro de Otamendi, born around 1510, was a Spanish conquistador who participated in the expeditions of Hernán Cortés in Mexico and later became one of the first settlers in the region of modern-day Guatemala.
During the Golden Age of Spanish literature in the 17th century, there was a notable poet and playwright named Gonzalo de Otamendi, who was born in Seville around 1620. His works, though not widely known today, were celebrated in his time and contributed to the rich cultural heritage of Spain.
In the realm of science, the name Otamendi is associated with José Otamendi, a renowned Argentine physician and medical researcher who lived from 1892 to 1958. He made significant contributions to the field of neurology and was recognized for his pioneering work in the study of brain tumors and surgical techniques.
More recently, Nicolás Otamendi, born in 1988, is a professional football player from Argentina who plays as a defender for the Portuguese club Benfica and the Argentine national team. He has represented his country in multiple World Cup tournaments and is considered one of the top defenders in modern football.
Throughout its history, the Otamendi surname has been present in various regions of Spain, as well as in Spanish-speaking countries in Latin America, reflecting the far-reaching influence of the Spanish colonial empire. While its exact origins may be shrouded in the mists of time, the name carries the essence of the rugged Basque landscape and the resilience of those who called it home.
Demographics
Among Census respondents with the surname Otamendi, the largest self-reported group is Hispanic at 95.6%. The next largest groups are White (4.4%).
The bar chart below shows how Otamendi 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 Otamendi surname at the time of the 2020 Census, not any inherent property of the name itself.
