Origin
Meaning and origin of Demaret
The surname DEMARET has its origins in France, with records dating back to the 12th century. It is derived from the Old French word "demer," meaning "to remain" or "to dwell," suggesting that the name may have been given to someone who lived in a particular place for an extended period.
One of the earliest known references to the name DEMARET can be found in the Cartulaire de Saint-Père de Chartres, a collection of charters and documents from the Abbey of Saint-Père in Chartres, France. This document, which dates back to the late 12th century, mentions a person named Petrus Demeratus, likely an early spelling variation of the modern DEMARET.
Another early record of the name comes from the Trésor des Chartes, a collection of royal charters and documents from the French monarchy. In a document dated 1278, a person named Johannes Demerez is mentioned, indicating that the name had already evolved into a more recognizable form by the late 13th century.
One notable bearer of the DEMARET surname was Jacques DEMARET, a French painter who lived from 1505 to 1570. He was known for his religious works and is particularly renowned for his altarpiece in the Church of Saint-Jean-au-Marché in Troyes, France.
In the 17th century, the name DEMARET was found in various regions of France, including Normandy and Picardy. This is evidenced by the birth records of individuals such as Nicolas DEMARET, born in Rouen, Normandy, in 1623, and Marie DEMARET, born in Amiens, Picardy, in 1678.
The DEMARET surname also has a connection to the town of Demaret-Montauban, located in the Champagne-Ardenne region of France. It is possible that the name originated from this locality, although the exact link has not been definitively established.
Other notable individuals with the DEMARET surname throughout history include:
1. Jean-Baptiste DEMARET (1768-1853), a French politician and lawyer who served as a deputy in the National Convention during the French Revolution.
2. Eugène DEMARET (1826-1898), a Belgian painter known for his landscapes and genre scenes.
3. Auguste DEMARET (1860-1936), a Belgian architect who designed several notable buildings in Brussels, including the Hôtel Métropole.
4. Jean-Marie DEMARET (1905-1975), a Belgian writer and poet who was a prominent figure in the Walloon literary movement.
5. Robert DEMARET (1947-2022), a French professional golfer who won numerous tournaments on the PGA Tour and the European Tour.

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