It is believed to have derived from an occupational name, referring to an individual who worked as a keeper or overseer of a castle or fortified dwelling, known as a "châtellier" or "châtelain" in Old French.
The name's earliest recorded instances can be found in various historical documents from the 13th and 14th centuries. One notable mention appears in the records of the Benedictine abbey of Saint-Riquier in Picardy, which references a certain Pierre DUCHATELLIER who served as a castellan in the year 1279.

The name is also linked to several place names, such as Châtellier-Châteaumur in the department of Eure-et-Loir, and Châtellier-sur-Yvette in the Île-de-France region.
One of the earliest notable figures associated with this surname was Jean DUCHATELLIER, a French knight and military commander who fought in the Hundred Years' War alongside Joan of Arc. He was born around 1390 in the town of Alençon and played a crucial role in the Siege of Orléans in 1429.
Another prominent individual bearing this name was Guillaume DUCHATELLIER (1475-1542), a respected lawyer and magistrate from Rouen, who served as a counselor in the Parliament of Normandy and was highly regarded for his legal expertise and integrity.

During the 17th and 18th centuries, the DUCHATELLIER name continued to be associated with nobility and landowners across various regions of France. Notable figures from this period include François DUCHATELLIER (1647-1721), a wealthy merchant and financier from Paris, and Marie-Anne DUCHATELLIER (1719-1798), a renowned painter and portraitist who was patronized by the French aristocracy.

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