Origin
Meaning and origin of Aybar
The surname AYBAR has its origins in the Iberian Peninsula, specifically in the regions of Spain and Portugal. It can be traced back to the 11th century, during the Moorish occupation of the region. The name is believed to derive from the Arabic word "aib," meaning "fault" or "defect," and the suffix "-ar," which is a common Arabic surname ending. This suggests that the name may have originally referred to a person with a perceived flaw or imperfection.
One of the earliest recorded instances of the name AYBAR can be found in the Libro de Repartimiento de Mallorca, a document from the 13th century that recorded the distribution of land and property among the Christian conquerors of the Balearic Islands. The name appears as "Aybar," suggesting that the spelling has remained relatively consistent over time.
During the 14th century, the name AYBAR began to spread beyond the Iberian Peninsula, likely as a result of the Reconquista and the expulsion of Moorish populations from Spain and Portugal. Records from this period show individuals with the surname AYBAR settling in other parts of Europe, such as Italy and France.
In the 15th century, a notable figure bearing the surname AYBAR was Diego de Aybar, a Spanish conquistador who participated in the conquest of Mexico under Hernán Cortés. He was born in Seville, Spain, around 1480 and died in Mexico City in 1541.
Another prominent individual with the surname AYBAR was Pedro de Aybar, a 16th-century Spanish soldier and explorer who played a significant role in the conquest of Peru. He was born in Seville around 1510 and died in Cusco, Peru, in 1561.
In the 17th century, the name AYBAR appeared in various historical records across Europe. One notable figure was Juan de Aybar y Velasco, a Spanish nobleman and military commander who served as the Governor of Gibraltar from 1629 to 1633.
The 18th century saw the spread of the surname AYBAR to the Americas, particularly in regions colonized by Spain and Portugal. One notable figure from this period was José Antonio de Aybar, a Spanish military officer and politician who served as the Governor of Cuba from 1762 to 1766.
In the 19th century, the name AYBAR continued to be found in various parts of the world, including the Americas and Europe. One noteworthy individual was Mariano Aybar, a Dominican military leader and politician who played a significant role in the Dominican War of Independence from Spain in the 1860s.

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 Aybar 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.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
