Origin
Meaning and origin of Monier
The surname Monier is of French origin, with its roots dating back to the medieval period. It is derived from the Old French word "monier," which means "a monk" or "a member of a monastic order." This suggests that the name may have initially been given as a descriptive name to someone who lived a monastic lifestyle or had close associations with a monastery.
The earliest recorded instances of the name Monier can be traced back to the 13th century in various regions of France, such as Normandy, Burgundy, and the Île-de-France region. Some variations in spelling, like "Monnier" and "Moinier," were also common during this time.
One notable historical reference to the name Monier is found in the Livre des Bourgeois de Rouen, a medieval French manuscript dating back to the 14th century, which lists several individuals bearing the surname Monier among the citizens of the city of Rouen.
In the 15th century, the name Monier appeared in several records, including those of Jean Monier (c. 1420-1490), a French architect and sculptor who was involved in the construction of the Châtelet in Paris. Another notable figure was Gilles Monier (c. 1455-1525), a French jurist and legal scholar who served as the president of the Parlement of Paris.
During the 16th century, the name Monier gained prominence with individuals like Claude Monier (c. 1530-1585), a French poet and translator known for his translations of classical works. Around the same time, there was also a notable family in the Champagne region known as the Moniers de Merville, who were renowned for their involvement in the wine trade.
In the 17th century, the name Monier was associated with Jean Monier (c. 1615-1688), a French Jesuit missionary who spent several years in Canada and was known for his work among the indigenous populations.
Another prominent figure with the surname Monier was Jean-Baptiste Monier (1699-1755), a French sculptor and architect who was instrumental in the design and construction of several notable buildings in Paris, including the Church of Saint-Sulpice.

The bar chart below shows how Monier 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 Monier surname at the time of the 2020 Census, not any inherent property of the name itself.
