Origin
Meaning and origin of Buezo
The surname Buezo is believed to have originated in Spain during the medieval period. It is thought to be derived from the Spanish word "buzo," which means "diver" or "deep-sea diver." This suggests that the name was likely given to someone who worked as a diver, perhaps in the fishing or pearl-diving industries.
One of the earliest recorded instances of the name Buezo can be found in the archives of the city of Seville, where a man named Juan Buezo is mentioned in a document dated 1492. This was the same year that Christopher Columbus set sail on his famous voyage to the Americas, so it is possible that Juan Buezo was a diver involved in the maritime industry during that time.
In the 16th century, there are records of a family by the name of Buezo living in the town of Moguer, located in the province of Huelva in southwestern Spain. This region was known for its thriving fishing industry, which lends further credence to the theory that the name Buezo was associated with those who worked as divers or in related occupations.
One notable individual with the surname Buezo was Francisco Buezo, a Spanish explorer who accompanied Hernán Cortés on his expedition to Mexico in the early 1500s. Buezo played a significant role in the conquest of the Aztec Empire and is mentioned in several historical accounts of the time.
Another prominent figure bearing the name Buezo was Pedro Buezo, a Spanish military officer who served in the Spanish Armada during the Anglo-Spanish War in the late 16th century. He is recorded as having participated in the famous naval battle against the English fleet in 1588.
In the 17th century, a family named Buezo settled in the town of Cadiz, located in southern Spain. One member of this family, Diego Buezo, was a successful merchant who traded goods between Spain and its colonies in the Americas.
As the centuries passed, the Buezo surname spread to other parts of Spain and eventually to other Spanish-speaking countries, particularly in Latin America. Notable individuals with the name Buezo include Jorge Buezo, a Chilean novelist and poet born in 1928, and Rafael Buezo, a Mexican artist and sculptor who lived from 1922 to 1998.
While the exact origins of the surname Buezo may never be known with certainty, its connection to the diving and maritime industries in Spain's coastal regions during the Middle Ages and beyond is a plausible and widely accepted theory.
Demographics

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