Origin
Meaning and origin of Lacourciere
The surname LACOURCIERE originated in France during the Middle Ages. It is derived from the Old French words "la cour" meaning "the court" and "cier" meaning "wax maker" or "chandler." This suggests that the name likely referred to an occupation or trade involving the production of candles or other wax-based products for the court or nobility.
The earliest recorded instances of the name date back to the 13th century in the region of Normandy, where it was often spelled as "Lacourcière" or "Lacoursierre." Records from this period indicate that individuals bearing this surname were employed in various capacities within the households and estates of noble families.
One of the earliest known bearers of the LACOURCIERE name was Jean Lacourcière, a chandler who lived in the village of Évreux, Normandy, in the late 13th century. His name appears in local tax records and land registries from that time.
In the 14th century, the name LACOURCIERE began to appear in official documents and records across other parts of northern France, particularly in the regions of Picardy and Île-de-France. This suggests that individuals with this surname may have migrated or established themselves in these areas during this period.
During the 16th and 17th centuries, several prominent figures with the LACOURCIERE surname emerged, including:
1. Nicolas Lacourcière (1540-1612), a renowned lawyer and legal scholar from Paris, who served as a magistrate in the Parlement of Paris.
2. Suzanne Lacourcière (1578-1645), a noblewoman from Rouen who became a prominent patron of the arts and supported several artists and writers during her lifetime.
3. Pierre Lacourcière (1620-1688), a French explorer and fur trader who played a significant role in the early exploration and settlement of parts of what is now eastern Canada.
In the 18th and 19th centuries, the LACOURCIERE name continued to be found across various regions of France, with notable individuals including:
1. Jacques Lacourcière (1742-1815), a military officer who served in the French army during the Napoleonic Wars and rose to the rank of brigadier general.
2. Émilie Lacourcière (1805-1882), a French author and poet from Lyon, who wrote several acclaimed works of poetry and literature during her lifetime.
Throughout its history, the LACOURCIERE surname has maintained a strong association with its French origins, although it has also been adopted and used in other parts of the world, particularly in regions with significant French cultural influence or immigration.
Demographics
Ancestry and ethnicity for Lacourciere

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