Origin
Meaning and origin of Chassey
The surname Chassey is of French origin, with its roots traced back to the northern regions of the country, particularly in the areas around Champagne and Burgundy. It is believed to have derived from the Old French word "chasse," meaning "hunt" or "chase," suggesting that the name was likely associated with individuals involved in hunting or forestry activities.
One of the earliest records of the name Chassey can be found in the cartularies (medieval records) of the Abbey of Cluny, a prominent Benedictine monastery in Burgundy, dating back to the 11th century. The name is mentioned in several land grants and transactions involving individuals bearing the Chassey surname.
In the 13th century, a notable figure named Jacques Chassey was recorded as a prominent landowner and influential figure in the town of Châlons-en-Champagne. His descendants continued to hold significant positions in the region for several generations.
During the 16th century, a branch of the Chassey family settled in the region of Lorraine, where they established themselves as respected members of the local nobility. One of the most prominent individuals from this line was Pierre de Chassey (1528-1602), a skilled military leader who served under the French kings Henry II and Charles IX.
In the 17th century, the Chassey surname gained further recognition with the birth of François Chassey (1635-1708), a renowned French architect and engineer. He was responsible for the design and construction of several notable buildings, including the Church of Saint-Sulpice in Paris and the Abbey of Saint-Germain-des-Prés.
Another noteworthy individual with the Chassey surname was Marguerite Chassey (1678-1744), a celebrated French painter who specialized in portraiture and religious scenes. Her works were highly regarded during her lifetime and can be found in various collections across Europe.
Throughout the centuries, the Chassey surname has also been associated with various place names in France, such as Chassey-lès-Montbozon, a commune in the Haute-Saône department, and Chassey-lès-Scey, a village in the Haute-Marne department. These place names may have influenced or been influenced by the surname's evolution over time.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
