Origin
Meaning and origin of Monzon
The surname Monzon has its origins in Spain, specifically in the region of Aragon. The name is believed to have emerged during the 12th century, derived from the Spanish word "monzón," which refers to a seasonal wind or monsoon.
The earliest recorded instances of the name Monzon can be traced back to the town of Monzón, located in the province of Huesca, Aragon. This town was historically significant during the Middle Ages, serving as a meeting place for the Cortes (parliament) of Aragon. It is likely that the surname Monzon originated from individuals who hailed from this town or the surrounding areas.
Historical records from the 13th century mention individuals with the surname Monzon, such as Pedro Monzon, a prominent landowner and knight who fought in the Reconquista (the Christian reconquest of the Iberian Peninsula from the Moors). Another notable figure was Martín Monzon, a renowned scholar and theologian who lived in the 15th century and authored several influential works on Catholic doctrine.
In the 16th century, the Monzon family gained prominence in Aragon, with Juan Monzon serving as a prominent military commander during the Revolt of the Brotherhoods (1520-1521). His son, Diego Monzon, followed in his footsteps and became a respected military leader, participating in various campaigns against the Ottomans in the Mediterranean.
The surname Monzon also spread beyond Spain's borders, with individuals bearing this name found in various parts of the Spanish Empire. One notable example is Hernán Monzon, a conquistador who accompanied Francisco Pizarro in the conquest of Peru in the 16th century.
During the 17th century, the Monzon family established itself in the New World, with several members settling in various Spanish colonies. One prominent figure was Juan Monzon de Castilla, a wealthy landowner and entrepreneur who played a significant role in the development of the sugar industry in Cuba.
As the name Monzon spread across Spain and its colonies, variations in spelling emerged, including Monzón, Monçon, and Monçón. Additionally, the name was occasionally found in combination with other surnames, such as Monzon y Pardo or Monzon de Aragón, reflecting the importance of lineage and regional affiliations.

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

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
