Origin
Meaning and origin of Chappius
The surname CHAPPIUS originates from France and can be traced back to the 12th century. It is derived from the Old French word "chapuis," which means "hat maker" or "hat seller." The name was initially given to individuals who worked in the hat-making trade.
The earliest recorded mention of the CHAPPIUS surname can be found in the Cartulaire de l'Abbaye de Saint-Père de Chartres, a medieval manuscript from the 12th century. This document contains references to individuals with the surname CHAPPIUS living in the Chartres region of northern France.
During the Middle Ages, the CHAPPIUS name was often associated with the town of Chapuis, located in the Burgundy region of eastern France. The town's name was likely derived from the same root as the surname, indicating a connection to the hat-making industry in that area.
One notable bearer of the CHAPPIUS surname was Jean Chappius, a French mathematician and astronomer born in 1546 in Saint-André-de-Chalençon, Haute-Alpes. He made significant contributions to the field of mathematics and published several works on astronomy and geometry.
Another prominent individual with the CHAPPIUS surname was François Chappius, a French painter born in 1624 in Rouen, Normandy. He was known for his religious paintings and worked on various commissions for churches and monasteries throughout France.
In the 18th century, Jacques Chappius (1720-1789) was a French historian and author from Lyons. He wrote several books on the history of the Lyons region and was a member of the local academic society.
The CHAPPIUS surname also appears in historical records from neighboring countries, such as Switzerland and Belgium, suggesting that individuals with this name migrated to other regions over time.
One notable Swiss bearer of the CHAPPIUS surname was Jean-Baptiste Chappuis (1765-1832), a politician and diplomat from Geneva. He served as the Swiss ambassador to France during the French Revolution and played a crucial role in maintaining diplomatic relations between the two countries.
While the CHAPPIUS surname is not as common today as it was in the past, it remains a part of the rich heritage and history of France, particularly in regions where the hat-making industry once thrived.

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

Does the Census include every surname?
