Origin
Meaning and origin of Lalonde
The surname Lalonde has its roots in France, specifically originating from the Normandy region during the Middle Ages. It is derived from the French phrase "la londe," which translates to "the heathland" or "the moorland." This suggests that the name may have been initially used to identify individuals who lived near or worked on such uncultivated lands.
During the 11th century, the name Lalonde can be traced back to the Normandy region of northern France. Historical records from that time period show various spellings, including Lalonde, Lallonde, and La Londe, indicating the name's evolution over time.
One of the earliest known mentions of the name Lalonde can be found in the Domesday Book, a comprehensive record of landholdings and property ownership commissioned by William the Conqueror in 1086. The entry refers to a landowner named Robert de Lalonde, who held lands in the county of Essex, England, after the Norman conquest.
In the 13th century, the name Lalonde appeared in documents related to the Hundred Years' War between England and France. A notable figure was Jean de Lalonde, a French knight who fought alongside Joan of Arc during the Siege of Orléans in 1429.
The 16th century saw the rise of a prominent Lalonde family in the Normandy region. Pierre Lalonde (1512-1578) was a respected farmer and landowner, known for his innovative agricultural practices and his involvement in local affairs.
During the 17th century, the name Lalonde gained prominence in the New World, as some members of the family emigrated to the French colonies in North America. One notable figure was Jacques Lalonde (1635-1712), a fur trader and explorer who established trading posts along the Great Lakes region.
In the 19th century, a famous bearer of the Lalonde name was Marie-Rose Lalonde (1819-1897), a French-Canadian educator and advocate for women's education. She founded several schools in Quebec and was instrumental in promoting the rights of women in education and society.
Other notable individuals with the surname Lalonde include:
1. Charles Lalonde (1878-1953), a Canadian politician and lawyer who served as a member of the House of Commons.
2. Émile Lalonde (1904-1987), a French-Canadian artist known for his impressionist paintings and landscapes.
3. Josée Lalonde (born 1964), a Canadian actress and comedian, known for her work in television and film.
4. Marc Lalonde (born 1939), a Canadian politician and lawyer who served as a member of the House of Commons and held various cabinet positions.
5. Suzanne Lalonde (1925-2003), a French-Canadian author and poet, known for her contributions to the literary scene in Quebec.

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

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
