Origin
Meaning and origin of Agregado
The surname AGREGADO has its origins in Spain, dating back to the 16th century. It is derived from the Spanish word "agregado," which means "attached" or "added." This name was given to individuals who were attached to a particular group, organization, or household.
In the early days, AGREGADO was often associated with individuals who held administrative or clerical positions within the Spanish royal court or religious institutions. They were considered part of the noble household or attached to the clergy, hence the name.
One of the earliest recorded instances of the name AGREGADO can be found in the records of the Spanish Inquisition during the 16th and 17th centuries. The name appears in documents detailing the trials and proceedings against individuals accused of heresy or other religious offenses.
During the Spanish colonization of the Americas, some individuals bearing the surname AGREGADO accompanied the conquistadors and settlers to the New World. They may have been members of the military, clergy, or administrative staff attached to the expeditions.
In the 18th century, a notable figure with the surname AGREGADO was Juan Antonio Agregado (1712-1789), a Spanish military officer who served in the Spanish colonies in the Americas. He was known for his role in the defense of Cartagena de Indias (present-day Colombia) against the British forces in 1741.
Another historical figure was María Josefa Agregado (1756-1832), a Spanish nun and writer who authored several religious texts and poems. Her works were widely circulated within the Catholic church and among the literary circles of her time.
In the 19th century, Pedro Agregado (1810-1885) was a prominent Spanish politician and lawyer. He served as a member of the Spanish parliament and was involved in drafting legal reforms during the reign of Queen Isabella II.
The surname AGREGADO also found its way to other Spanish-speaking countries through migration and colonization. In Mexico, for instance, there are records of individuals with the surname AGREGADO dating back to the 17th century, possibly descendants of Spanish settlers or officials.

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