Origin
Meaning and origin of Lauzon
The surname Lauzon is of French origin, originating from the Normandy region of northern France. It is believed to be derived from the Old French term "l'auson," which means "the little stream." This suggests that the name may have originally referred to someone who lived near a small creek or brook.
The earliest recorded instances of the Lauzon surname date back to the 12th century in Normandy. In 1195, a man named Guillaume de Lauzon was mentioned in the records of the Abbey of Fécamp, a Benedictine monastery located in the region. This suggests that the name was established in Normandy by this time.
During the Middle Ages, the Lauzon surname also appeared in various records and manuscripts across Normandy and other parts of northern France. For instance, a Robert Lauzon was listed in the census records of the town of Rouen in 1278.
In the 16th century, the Lauzon family gained prominence with Jean de Lauzon, who was born in 1583 and served as the Governor of New France (present-day Quebec) from 1651 to 1657. He played a significant role in the early administration and development of the French colony in North America.
Another notable figure with the Lauzon surname was François de Lauzon, who lived from 1622 to 1666. He was the son of Jean de Lauzon and served as a member of the Sovereign Council of New France, which was the governing body of the colony at the time.
In the 19th century, Charles Lauzon, born in 1820 in France, became a prominent architect and engineer. He was responsible for designing several notable buildings in Paris, including the Gare de l'Est railway station.
The Lauzon surname has also been associated with various place names throughout history. For example, the town of Lauzon, located across the St. Lawrence River from Quebec City, was named after Jean de Lauzon, the former governor of New France.
Overall, the surname Lauzon has a rich history spanning several centuries, originating in the Normandy region of France and eventually spreading to other parts of the world through the French colonial expansion and emigration.

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.

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

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Lauzon (2000, 2010, 2020).
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.
