Origin
The surname DECHAMPS finds its origins in France, emerging during the medieval period. It is derived from the Old French phrase "de champs," which translates to "of the fields" or "from the fields." This suggests that the name may have initially been used to identify individuals who lived or worked in rural areas or had an association with agricultural activities.
One of the earliest recorded instances of the name DECHAMPS can be traced back to the 13th century in the northern regions of France, particularly in the provinces of Picardy and Normandy. In historical records from this era, the name appeared with various spellings, such as "de Champ," "des Champs," and "Dechamps."
The DECHAMPS name is notably mentioned in the Rolls of the Battell Abbey, a manuscript dating back to the late 11th century. This document contains a record of the Norman soldiers who accompanied William the Conqueror during the Norman Conquest of England in 1066. However, it is uncertain whether the name referred to in this manuscript is directly linked to the modern DECHAMPS surname.
One of the earliest documented individuals bearing the DECHAMPS name was Jean Dechamps, a prominent French scholar and theologian who lived from around 1280 to 1349. He was known for his writings on various theological and philosophical topics and served as the Rector of the University of Paris.
In the 15th century, the DECHAMPS name gained prominence in the city of Dijon, located in the Burgundy region of France. Pierre Dechamps (1442-1512) was a notable figure during this period, serving as a magistrate and prominent citizen of Dijon. His descendants continued to play influential roles in the city's governance and affairs for several generations.
Another notable figure was Jacques Dechamps (1619-1692), a French Jesuit priest and missionary who traveled to North America in the mid-17th century. He is known for his work among the Native American tribes in the Great Lakes region, particularly the Huron and Iroquois nations.
During the 16th and 17th centuries, the DECHAMPS name also appeared in various regions of France, including Normandy, Brittany, and the Île-de-France region surrounding Paris. Individuals such as René Dechamps (1588-1643), a lawyer and magistrate from Normandy, and Antoine Dechamps (1635-1714), a renowned architect from Paris, contributed to the name's legacy during this period.
Demographics
Among Census respondents with the surname Dechamps, the largest self-reported group is White at 78.5%. The next largest groups are Hispanic (11.6%) and Black (8.3%).
The bar chart below shows how Dechamps 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 Dechamps surname at the time of the 2020 Census, not any inherent property of the name itself.
