Origin
Meaning and origin of Iguado
The surname "IGUADO" has its origins in the Basque region of northern Spain and southwestern France. It is believed to have emerged in the 14th century, derived from the Basque word "igualdu," which means "to level" or "to equalize." This suggests that the name may have been associated with occupations involving land surveying or construction work.
One of the earliest recorded instances of the Iguado surname can be found in the Basque provincial archives of Navarre, dated back to the late 15th century. Here, the name is mentioned in connection with a family of landowners from the town of Pamplona.
During the 16th and 17th centuries, the Iguado name spread across various parts of Spain, particularly in the regions of Castile and Aragon. Notable individuals bearing this surname include Juan Iguado (1502-1572), a prominent architect who contributed to the design of several churches and monasteries in Toledo and Valladolid.
As the Spanish Empire expanded across the Atlantic, the Iguado name also found its way to the Americas. In the 18th century, records show the presence of Iguado families in various parts of Latin America, including Mexico, Colombia, and Peru. One such individual was Pedro Iguado (1712-1789), a Spanish explorer and cartographer who played a crucial role in mapping the Amazon basin.
In the 19th century, the Iguado surname gained recognition in the field of literature. Miguel Iguado (1825-1901), a renowned Spanish novelist and playwright, achieved critical acclaim for his works depicting the lives of the Basque people and their cultural traditions.
Another noteworthy figure was Isabel Iguado (1867-1942), a pioneering feminist and educator who advocated for women's rights and established several schools for girls in Madrid and Barcelona.
While the surname Iguado is relatively uncommon today, it continues to be found in various parts of Spain, particularly in the Basque Country and surrounding regions, as well as among Hispanic communities in the Americas.

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