Origin
Meaning and origin of Derosiers
The surname DEROSIERS originated in France during the Middle Ages. It is derived from the French words "de" meaning "of" and "rosiers" meaning "rose bushes" or "rose gardens." This suggests that the name likely referred to a person who lived near or owned rose bushes or gardens.
The name can be traced back to the northern regions of France, particularly in the areas around Normandy and Brittany. It is believed to have originated as a toponymic surname, referring to a specific place or location associated with rose bushes or gardens.
One of the earliest recorded instances of the DEROSIERS name can be found in the Cartulaire de Notre-Dame de Paris, a collection of medieval charters and documents relating to the Cathedral of Notre-Dame in Paris, dating back to the 12th century.
In the 13th century, a nobleman named Guillaume DEROSIERS was mentioned in records from the Duchy of Normandy. He was a landowner and vassal of the Duke of Normandy during the reign of King Philip II of France.
During the 16th century, Jacques DEROSIERS (c. 1520-1582) was a prominent merchant and trader in the city of Lyon, known for his involvement in the silk trade with Italy and the Levant.
In the 17th century, Marie DEROSIERS (1623-1701) was a French nun and educator who founded several schools for girls in the city of Rouen. She was known for her dedication to providing education to underprivileged children.
Another notable figure was Pierre DEROSIERS (1685-1748), a French naval officer and explorer who participated in several expeditions to the West Indies and the Caribbean. He is credited with mapping and charting several islands in the region.
In the 18th century, Jean-Baptiste DEROSIERS (1758-1832) was a prominent lawyer and politician from Normandy. He served as a deputy in the French National Assembly during the French Revolution and was actively involved in the drafting of the Declaration of the Rights of Man and of the Citizen.
While the name DEROSIERS has its roots in France, it has since spread to other countries through migration and immigration. However, the historical records and accounts mentioned above provide insight into the origins and early bearers of this surname.

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.

Keep in mind that these are self-reported numbers.
