Origin
Meaning and origin of Giron
The surname Giron is of Spanish origin, originating from the region of Castile in the Iberian Peninsula. It is believed to have derived from the Spanish word "girón," which means "corner," "wedge," or "triangular piece of cloth." This suggests that the name may have initially been associated with someone who lived near a particular corner or distinctive triangular-shaped land.
Historically, the name Giron can be traced back to the 10th century, during the era of the Reconquista, when Christian kingdoms in the Iberian Peninsula were engaged in a prolonged conflict with the Moors. Some early records mention individuals bearing the Giron name, such as Pedro Girón, who fought alongside King Alfonso VIII of Castile in the Battle of Las Navas de Tolosa in 1212.
The Giron family became prominent nobles in the Kingdom of Castile, and their descendants played influential roles in the political and military affairs of the region. One notable figure was Juan Téllez-Girón (1456-1528), a Spanish nobleman and military leader who served as the Grand Master of the Order of Santiago and fought in the Conquest of Granada.
During the 16th century, the Giron name appeared in various historical records, including the chronicles of the Spanish conquest of the Americas. Juan Girón (c. 1510-1554), a Spanish conquistador, participated in the conquest of Peru and later led a rebellion against the Spanish crown in Panama.
Another notable individual with the Giron surname was Pedro Agustín Girón (1778-1846), a Spanish military officer and politician who served as the Prime Minister of Spain from 1842 to 1843. He played a significant role in the political events surrounding the reign of Queen Isabella II.
The Giron name has also been associated with several Spanish writers and artists throughout history, such as Juan Ruiz de Alarcón y Mendoza (1581-1639), a prominent Spanish playwright and writer of the Golden Age, and Juan Bautista Girón (1613-1684), a Spanish painter known for his religious works and portraits.
While the Giron surname originated in Spain, it has since spread to various parts of the world, including Latin America and other regions with Spanish cultural influence. However, the historical roots and earliest recorded instances of the name can be traced back to the medieval period in the Castilian region of the Iberian Peninsula.

The bar chart below shows how Giron 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 Giron 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.
