Origin
Meaning and origin of Anasco
The surname ANASCO is believed to have its origins in Spain, dating back to the 15th century. It is thought to be derived from the Spanish word "añasco," which means "old" or "ancient." This suggests that the name may have been initially given to someone who lived in an old or ancient settlement.
The earliest known records of the surname ANASCO can be found in various historical documents from the regions of Andalusia and Extremadura in southern Spain. One notable mention is in the archives of the town of Écija, where a certain Juan Anasco is listed as a landowner in the year 1487.
As the name spread across Spain and into other parts of Europe, it underwent various spelling variations, such as Anascio, Annasco, and Añasco. These variations were likely influenced by regional dialects and the preferences of local scribes or record keepers.
In the 16th century, the ANASCO surname made its way to the New World, carried by Spanish explorers and settlers. One of the earliest recorded instances of the name in the Americas is that of Pedro Anasco, a soldier who accompanied Hernán Cortés in the conquest of Mexico in the 1520s.
Throughout the centuries, several notable individuals have borne the ANASCO surname. One such person was Juan Bautista Anasco, a Spanish military officer and explorer who led expeditions to the Bahamas and Florida in the late 16th century. Another notable figure was Gaspar de Anasco, a Spanish missionary who worked among the indigenous populations of New Spain (present-day Mexico) in the 17th century.
In the realm of literature, the poet and playwright Juan de Anasco y Mendoza, born in Seville in 1592, was a prominent figure of the Spanish Golden Age. His works, which include plays and poetry collections, contributed significantly to the cultural landscape of his time.
Moving into the 19th century, we find José María Anasco, a Mexican politician and military leader who played a role in the Mexican War of Independence against Spain in the early 1800s.
It is worth noting that while the ANASCO surname has its roots in Spain, it has since spread to various parts of the world, particularly through Spanish colonization and migration. However, the earliest and most significant historical references to the name can be traced back to the Iberian Peninsula and its influence in the Americas.

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