Origin
Meaning and origin of Delarme
The surname DELARME is of French origin, tracing its roots back to the 13th century. It is believed to have originated in the northern region of France, particularly in areas like Normandy and Picardy. The name is derived from the Old French words "de l'arme," which translates to "of the weapon" or "of the arms."
This surname likely has a connection to the medieval practice of adopting descriptive surnames based on occupations or personal characteristics. In this case, DELARME may have been initially assigned to an individual who worked as a weaponsmith, armorer, or someone associated with the manufacturing or maintenance of arms and weapons during that era.
The earliest recorded instances of the DELARME surname can be found in various medieval records and documents from the 13th and 14th centuries. One notable mention is in the Rolls of the Parlement of Paris from 1286, where a certain Jean DELARME was listed as a citizen of the city.
In the 15th century, the name DELARME appeared in the Armorial Général de France, a comprehensive registry of French nobility and gentry compiled in the late 17th century under the orders of King Louis XIV. This suggests that by this time, some branches of the DELARME family had achieved a degree of social standing and recognition.
Throughout the centuries, several individuals with the surname DELARME have made noteworthy contributions in various fields. For instance, Pierre DELARME (1561-1637) was a renowned French jurist and legal scholar who served as a judge in the Parlement of Paris. His treatises on civil and criminal law were widely influential during his time.
Another notable figure was Marie-Marguerite DELARME (1719-1796), a French poet and dramatist who gained recognition for her lyrical works and plays. Her collection of poems, "Les Fleurs du Parnasse," published in 1765, was highly acclaimed by literary circles of the day.
In the 19th century, Louis DELARME (1812-1879) made his mark as a prominent French architect. He was responsible for designing several iconic buildings in Paris, including the Palais de la Bourse (Paris Stock Exchange) and the Grand Hôtel du Louvre.
The name DELARME also found its way into the military annals of France. During the Napoleonic Wars, General Jacques DELARME (1776-1842) distinguished himself as a skilled cavalry commander, playing a crucial role in several pivotal battles against the Allied forces.
Throughout its long history, the DELARME surname has undergone various spelling variations, such as Delarme, De L'Arme, Delarmes, and Delarmet, reflecting regional linguistic differences and the evolution of the French language 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 Delarme surname at the time of the 2020 Census, not any inherent property of the name itself.
