Origin
The surname "BOUBION" is believed to have originated in France, likely during the medieval period. It is thought to have derived from the Old French word "boubion," which referred to a small stream or brook. This suggests that the name may have been initially used as a descriptive surname for someone who lived near a small watercourse.
One of the earliest recorded instances of the name "BOUBION" can be found in the Cartulaire de l'abbaye de Saint-Père de Chartres, a medieval cartulary from the 12th century. This document mentions a person named Robertus de Boubion, indicating that the name was already in use by that time.
In the 13th century, there is a record of a nobleman named Raoul de Boubion, who was a vassal of the Count of Champagne. This suggests that the Boubion family may have held a certain degree of nobility or prominence in the region.
During the 14th century, a notable figure named Jean Boubion was a merchant and alderman in the city of Paris. He is mentioned in several historical documents from that period, indicating his involvement in the city's governance and trade.
In the late 16th century, a French Protestant minister named Jacques Boubion played a role in the French Wars of Religion. He was a vocal supporter of the Huguenot cause and faced persecution for his beliefs.
In the 18th century, a French botanist named Pierre-André Boubion made significant contributions to the study of plant life. He was particularly known for his work on the flora of the Caribbean region, where he spent several years collecting and documenting various plant species.
Throughout history, the surname "BOUBION" has been associated with various locations in France, including villages and hamlets that may have derived their names from the same root word. Examples include Boubion-en-Auvergne, Boubion-le-Petit, and Boubion-sur-Vienne.
Overall, the surname "BOUBION" has a rich history rooted in medieval France, with connections to nobility, commerce, religion, and natural sciences. Its origins can be traced back to a descriptive term related to small streams or brooks, reflecting the geographic and linguistic landscape of the regions where it first emerged.
Demographics
Among Census respondents with the surname Boubion, the largest self-reported group is Hispanic at 86.0%. The next largest groups are White (12.0%) and Two or More Races (2.0%).
The bar chart below shows how Boubion 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 Boubion surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
