Origin
Meaning and origin of Guittard
The surname GUITTARD has its origins in France, tracing back to the medieval period. It is derived from the Old French word "guitard," which means "one who keeps watch" or "guard." This suggests that the name may have been initially associated with a profession or occupation related to guarding or protecting.
The name GUITTARD is believed to have originated in the northern regions of France, particularly in areas such as Normandy and Brittany. It is found in various historical records and manuscripts from these regions, dating back to the 12th and 13th centuries.
One of the earliest recorded instances of the name GUITTARD can be found in the Cartulaire de l'Abbaye de Saint-Martin de Troarn, a medieval cartulary from the 12th century that documents the affairs of a Benedictine abbey in Normandy. The name appears in this record, indicating its presence in the region during that time.
In the 13th century, a nobleman named Robert GUITTARD was mentioned in the Livre des Bourgeois de Rouen, a historical record that documented the citizens of the city of Rouen in Normandy. This reference provides evidence of the name's usage among the nobility and upper classes in medieval France.
During the 14th century, a notable figure bearing the name GUITTARD was Jehan GUITTARD, a merchant and financier from Paris who was involved in the court of King Charles VI of France. He played a prominent role in the financial affairs of the kingdom during his lifetime (c. 1340 – 1410).
Another historically significant individual with the surname GUITTARD was François GUITTARD, a French explorer and navigator who participated in several expeditions to the Americas in the late 16th century. He accompanied the famous explorer Jacques Cartier on his voyages to Canada and helped establish French settlements in the New World.
In the 17th century, a renowned French mathematician and astronomer named Jean-Denis GUITTARD (1635 – 1718) made significant contributions to the fields of mathematics and astronomy. He was a member of the prestigious French Academy of Sciences and worked on various astronomical calculations and observations.
The name GUITTARD has also been associated with various place names and localities in France, such as the town of Guittard in the department of Mayenne, as well as other villages and hamlets bearing similar spellings, like Guitard and Guittart.

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