Origin
The surname Girouard is of French origin, with roots dating back to the medieval period in France. It is believed to have derived from the Old French words "girer" and "ouard," which respectively mean "to turn" and "guard" or "watchman." This suggests that the name may have been initially associated with individuals who had occupations related to guarding or patrolling, perhaps as sentries or watchmen.
One of the earliest recorded instances of the Girouard surname can be found in the historic Domesday Book, a comprehensive survey of land and property ownership commissioned by William the Conqueror in 1086. This document includes references to individuals bearing variations of the name, such as "Girouart" and "Girouarde," indicating the presence of the surname in Normandy and other parts of northern France during the 11th century.
During the Middle Ages, the Girouard family established a presence in various regions of France, including Normandy, Brittany, and the Loire Valley. Some historical records suggest that members of the Girouard family were involved in military service, potentially serving as guards or sentries in castles or fortified towns.
One notable figure with the Girouard surname was Jean Girouard (1545-1618), a French soldier and explorer who participated in several expeditions to the Americas during the late 16th and early 17th centuries. He is credited with being one of the first Europeans to explore parts of what is now eastern Canada and the northeastern United States.
Another prominent individual bearing the Girouard name was Pierre Girouard (1765-1838), a French-Canadian businessman and landowner who played a significant role in the early development of the city of Montreal. He was involved in various commercial ventures and owned extensive property holdings in the region.
In the 19th century, Louis Girouard (1825-1892) was a renowned French-Canadian educator and author. He founded several schools and educational institutions in Quebec and wrote extensively on topics related to education and French-Canadian culture.
Léon Girouard (1890-1970) was a French military officer and civil engineer who served in both World Wars. He is particularly notable for his role in overseeing the construction of the Suez Canal during the early 20th century.
Lastly, Désiré Girouard (1836-1911) was a Canadian politician and lawyer who served as a member of the House of Commons of Canada and held various political offices in the province of Quebec.
While the Girouard surname has its roots in France, it has since spread to various parts of the world, including Canada, the United States, and other regions with significant French-speaking populations or historical ties to France.
Demographics
Among Census respondents with the surname Girouard, the largest self-reported group is White at 91.8%. The next largest groups are Black (3.6%) and Two or More Races (2.4%).
The bar chart below shows how Girouard 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 Girouard surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
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.
