Origin
Meaning and origin of Mondares
The surname Mondares has its origins in Spain, tracing back to the medieval period around the 10th or 11th century. It is believed to have derived from the Spanish word "mondar," which means "to peel" or "to shell," possibly referring to an occupation related to agriculture or food production. The earliest recorded instances of this surname appear in historical records from the regions of Galicia and Asturias in northern Spain.
One of the earliest known bearers of the Mondares surname was Rodrigo Mondares, a nobleman who lived in the 13th century and was mentioned in a charter from the Kingdom of Castile and León. Another prominent figure was Juan Mondares, a merchant and landowner who lived in the city of Santiago de Compostela in the 15th century.
In the 16th century, the Mondares family had established itself as a respected lineage in the town of Ribadavia, located in the province of Ourense, Galicia. During this time, the name was sometimes spelled as "Mondarez" or "Mondariz," reflecting regional variations in pronunciation and orthography.
One notable individual from this era was Alonso Mondares, a military officer who served under King Philip II of Spain during the Spanish Armada campaign against England in 1588. He is recorded as having participated in the Battle of Gravelines, a significant naval engagement of that conflict.
In the 17th century, a branch of the Mondares family migrated to the Americas, settling in the Spanish colonies of Mexico and Peru. One of the earliest recorded instances of the name in the New World is that of Hernán Mondares, a soldier and explorer who accompanied the conquistador Francisco Pizarro in the conquest of Peru in the 1530s.
Another prominent figure was María Mondares, a woman from Seville, Spain, who lived in the late 17th century and was involved in the establishment of a convent in the city of Puebla, Mexico. Historical records mention her as a benefactor and patron of the religious order.
As the centuries progressed, the Mondares surname spread to other regions of Spain and Latin America, with various individuals making notable contributions in fields such as arts, literature, and politics. However, it is important to note that the prevalence and distribution of the surname may have fluctuated over time due to migration patterns, socioeconomic factors, and historical events.

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