Origin
Meaning and origin of Mabardy
The surname MABARDY is believed to have originated in the region of Normandy in France during the Middle Ages. It is thought to be derived from the Old French words "mal" and "bardy," which translates to "bad" and "bard" or "minstrel," respectively. This combination suggests that the name may have been initially given to an individual who was considered a poor or unskilled bard or minstrel.
In the early 12th century, records show variations of the name, such as "Malbardy" and "Malbardey," appearing in medieval documents from the Normandy region. It is possible that the name was initially adopted as a descriptive nickname before becoming a hereditary surname.
One of the earliest recorded instances of the name MABARDY can be found in the Cartulary of Fécamp Abbey, a medieval manuscript from the late 11th century. This document contains a reference to a landowner named Radulfus Mabardy, who owned property in the vicinity of the abbey.
In the 13th century, a notable figure bearing the name MABARDY was Sir William Mabardy, a Norman knight who took part in the Seventh Crusade to the Holy Land between 1248 and 1254. He is mentioned in various chronicles and accounts of the crusade.
Another historical figure of note was Jean Mabardy, a French poet and playwright who lived in the late 15th century. His work "Le Mystère de la Passion" was a popular medieval play depicting the Passion of Christ and was performed in various towns across Normandy.
During the 16th century, the name MABARDY appeared in records from the town of Dieppe in Normandy. One entry from 1562 mentions a merchant named Jacques Mabardy, who was involved in the local textile trade.
In the 17th century, a family of MABARDY resided in the village of Longchamps, near Rouen. One member, Pierre Mabardy, born in 1618, was a prominent landowner and served as a local magistrate.
While the surname MABARDY is not among the most common in France today, it has a rich history rooted in the cultural traditions of medieval Normandy, with references spanning from the 11th to the 17th centuries.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
