Origin
Meaning and origin of Jiron
The surname Jiron has its origins in Spain, with records of the name dating back to the 16th century. It is believed to be derived from the Spanish word "jirón," which means a piece or strip of cloth, suggesting a possible connection to occupations related to textile or clothing industries.
One of the earliest known references to the name Jiron can be found in the archives of the Spanish Inquisition, where a certain Juan Jiron was mentioned as a defendant in a trial held in Seville in the year 1567. This record provides valuable insight into the historical presence of the name in the region.
In the 17th century, the Jiron surname appeared in various municipal records and parish registers across several Spanish provinces, such as Andalusia, Extremadura, and Castile. This suggests that the name had spread and established itself in different regions of the country during this period.
The earliest known bearer of the Jiron surname was Alonso Jiron, a merchant and landowner who lived in the city of Cordoba in the late 16th century. He was a prominent figure in the local community and his descendants continued to use the Jiron surname for several generations.
Another notable individual with the Jiron surname was Diego Jiron, a Spanish explorer and navigator who accompanied the famous expedition of Juan Ponce de León to present-day Florida in 1521. Jiron's accounts of the journey provide valuable historical insights into the early Spanish exploration of the Americas.
In the 19th century, a prominent figure named Gaspar Jiron gained recognition as a leading political figure and activist in the fight for Spanish independence from French rule. Born in 1785 in the province of Seville, Jiron played a crucial role in the resistance movement against the Napoleonic occupation.
Throughout history, the Jiron surname has also been associated with various places and toponyms. For example, the village of Girón in the province of Burgos, Spain, may have a connection to the surname, although the exact relationship is not well-documented.
While the surname Jiron is not among the most common in Spain, it has a rich historical legacy spanning several centuries and has been borne by individuals from diverse backgrounds, including merchants, explorers, and political activists.

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

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Jiron (2000, 2010, 2020).
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.
