Origin
Meaning and origin of Culebro
The surname Culebro has its origins in Spain, originating in the late 15th century. The name is derived from the Spanish word "culebra," which means snake. It is believed that the name was initially given as a descriptive nickname to someone who was associated with snakes in some way, perhaps a snake charmer or someone known for their agility and quickness.
One of the earliest recorded instances of the Culebro surname can be found in the Spanish town of Culebro, located in the province of Alicante. This town likely took its name from the Spanish word "culebra," suggesting a connection between the place and the surname. The name Culebro also appears in various historical records from the 16th and 17th centuries, including church records and municipal documents.
In the late 16th century, a notable figure named Juan Culebro was a prominent merchant and landowner in the city of Seville. He played a significant role in the city's trade and commerce during the height of Spain's Golden Age. Another notable Culebro was Rodrigo Culebro, a Spanish explorer who accompanied Hernán Cortés on his expedition to conquer Mexico in the early 16th century.
During the 18th century, the Culebro family gained recognition in the field of art and literature. Pedro Culebro (1705-1782) was a renowned painter and portraitist, known for his works depicting the Spanish aristocracy. His contemporary, María Culebro (1712-1789), was a celebrated poet and playwright whose works explored themes of love, religion, and social commentary.
In the 19th century, the Culebro name gained prominence in the world of politics and military affairs. General Emilio Culebro (1825-1897) was a prominent figure in the Spanish Army, leading several successful campaigns against the Carlists during the Carlist Wars. He was also a respected military strategist and author of several books on military tactics.
Throughout its history, the Culebro surname has been associated with various professions and areas of expertise, from art and literature to commerce and military service. While the name's exact origins may be shrouded in mystery, its connection to the symbolic snake and its connotations of agility and cunning have endured over the centuries.

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