Origin
Meaning and origin of Oguendo
The surname OGUENDO is believed to have originated in Spain, likely during the medieval period. It is thought to be derived from the Basque language, which has its roots in the Pyrenees region spanning parts of modern-day Spain and France. Some linguists suggest the name may be linked to the Basque word "oguena," meaning "bread," possibly indicating an early association with bakers or millers.
One of the earliest recorded instances of the OGUENDO name can be found in a 14th-century municipal record from the town of Bilbao, located in the Basque region of northern Spain. This document mentions an individual named Pedro de Oguendo, who held a prominent position within the local government at that time.
In the 16th century, a notable figure bearing the OGUENDO surname was Juan de Oguendo, a Spanish navigator and explorer who accompanied Ferdinand Magellan on his historic circumnavigation of the globe between 1519 and 1522. Oguendo assumed command of the expedition after Magellan's death, though he ultimately perished during the voyage.
Another significant bearer of the OGUENDO name was Domingo de Oguendo, a 17th-century Spanish naval officer and admiral. He played a crucial role in several military campaigns against the Dutch and English during the Eighty Years' War and the Anglo-Spanish War, respectively.
In the realm of literature, Miguel de Oguendo y Alvarado, born in 1638, was a renowned Spanish poet and playwright. His works, including the play "El Caballero de Olmedo," contributed to the Golden Age of Spanish theater and literature.
Jumping forward to the 19th century, José María Oguendo y Fernández, a Spanish military officer and politician, gained prominence during the Carlist Wars. Born in 1809, he served as a general in the Carlist army and later held various political positions, including that of a senator.
Throughout its history, the OGUENDO surname has maintained a strong presence in Spain, particularly in the Basque region, where its roots can be traced. However, due to migration and global dispersal, individuals bearing this name can now be found in various parts of the world.

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