Origin
Meaning and origin of Herazo
The surname HERAZO originates from Spain and can be traced back to the 15th century. It is believed to have derived from the Spanish word "herrazo," which means "large nail" or "spike." This suggests that the name may have been given to someone who worked with metal or had a distinct physical characteristic related to nails or spikes.
One of the earliest recorded instances of the name HERAZO can be found in the baptismal records of the parish of San Pedro in Seville, Spain, where a certain Alonso Herazo was baptized in 1487. Another notable historical figure with this surname was Hernando Herazo, a Spanish conquistador who accompanied Francisco Pizarro on his conquest of Peru in the 16th century.
In the 17th century, the HERAZO surname appeared in various documents from the Canary Islands, suggesting that individuals bearing this name may have migrated from the Spanish mainland to the islands during this period. One such record mentions a Juan Herazo, a prominent landowner in the town of Tegueste, Tenerife, in the late 1600s.
As the Spanish empire expanded across the Americas, the HERAZO surname also spread to the New World. In the early 19th century, a notable figure named Tomás Herazo y Montes de Oca (1789-1854) was a Colombian poet and politician who served as the governor of the province of Cartagena.
Another remarkable individual with the HERAZO surname was Juan José Herazo (1920-1992), a Colombian poet and writer widely regarded as one of the most influential figures in Latin American literature of the 20th century. His most acclaimed work, "El Viaje del Agua" ("The Journey of Water"), published in 1962, earned him widespread recognition and numerous literary awards.
The HERAZO name has also been associated with various place names in Spain and Latin America. For example, there is a small town called Herazo in the province of Seville, Spain, as well as a municipality named Herazo in the department of Córdoba, Colombia.

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