Origin
Meaning and origin of Aguillon
The surname Aguillon originated in France during the medieval period, likely in the 11th or 12th century. It is derived from the Old French word "aguillon," which means "spur" or "goad." This suggests that the name may have been given to someone who worked with spurs or goads, perhaps a maker of these items or someone who used them in their occupation, such as a farmer or a spur-maker.
One of the earliest recorded instances of the name Aguillon can be found in the Cartulaire de l'abbaye de Conches, a collection of charters and documents from the Conches Abbey in Normandy, dating back to the 12th century. The name is also mentioned in various other medieval records and documents from different regions of France.
During the Middle Ages, the name Aguillon appeared in various spellings, such as Aiguillon, Aguillón, and Aguilloun, reflecting the regional variations in pronunciation and orthography at the time. Some notable historical figures who bore this surname include:
1. Pierre d'Aiguillon (c. 1235-1311), a French nobleman and military leader who fought in the Crusades and served as the Grand Master of the Knights Templar from 1307 to 1311.
2. Antoinette d'Aiguillon (1572-1635), a French noblewoman and philanthropist who founded the Order of the Canonesses of St. Augustine and several hospitals in Paris.
3. Marie-Madeleine d'Aiguillon (1604-1675), a French noblewoman and courtier who was a prominent figure in the court of Louis XIII and served as the Duchess of Aiguillon.
4. Armand de Vignerot du Plessis, Duc d'Aiguillon (1720-1788), a French nobleman and military leader who served as the Secretary of State for Foreign Affairs under Louis XV.
5. Emmanuel-Armand de Vignerot du Plessis, Duc d'Aiguillon (1720-1804), a French diplomat and military officer who served as the Governor-General of Brittany and later as the Minister of War under Louis XVI.
The Aguillon surname has also been associated with various place names in France, such as Aiguillon, a commune in the Lot-et-Garonne department, and Aiguillon-sur-Vie, a commune in the Vendée department. These place names may have influenced the surname or vice versa, as it was common for people to take their surnames from the places they lived or were associated with.

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 Aguillon 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.
