Origin
The surname Mustard is an English surname that originated as an occupational name for a mustard maker or seller. It is derived from the Old French word "mustarde," which comes from the Latin words "mustum" (must, or young unfermented wine) and "ardens" (hot or burning). This suggests that the name originally referred to someone who made or sold a spicy condiment made with must.
The earliest recorded instance of the surname Mustard dates back to the 13th century in Cambridgeshire, England. One of the earliest known bearers of the name was Robert Mustard, who is mentioned in tax records from 1273 in Fulbourn, Cambridgeshire.
In the 14th century, the surname Mustard appeared in various records across England, including the Subsidy Rolls of Worcestershire from 1327, which listed a John Mustard. The Hundred Rolls of Huntingdonshire from 1349 also mentioned a William Mustard.
The Mustard surname can be traced back to several place names in England, such as Mustard Green in Cambridgeshire and Mustard Pot in Gloucestershire. These place names likely derived from the occupational name, indicating areas where mustard makers or sellers lived and worked.
One notable historical figure with the surname Mustard was Richard Mustard (c. 1530-1611), an English merchant and politician who served as Lord Mayor of London in 1592. Another was William Mustard (c. 1595-1679), an English clergyman who became the Bishop of Peterborough in 1667.

- David Mustard (1842-1916), a Scottish-born Australian politician who served as a member of the Parliament of Victoria.
- Leonard Mustard (1888-1957), an English cricketer who played first-class cricket for Gloucestershire and Oxford University.
The Mustard surname has been present in various parts of England for centuries and has a rich history rooted in the occupational trade of making and selling mustard. While the name has evolved over time, it continues to carry the legacy of its occupational origins.
Demographics
Among Census respondents with the surname Mustard, the largest self-reported group is White at 93.0%. The next largest groups are Two or More Races (3.1%) and Hispanic (2.0%).
The bar chart below shows how Mustard 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 Mustard 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.
