Origin
The surname Gilliard originated in France and is derived from the medieval French given name Gillard or Giliard. These names stem from the Old German word "Gisilhard," which means "brave with the spear." The earliest recorded examples of the Gilliard surname date back to the 12th century in Normandy, France.
One of the earliest known bearers of the Gilliard name was Renaud Gilliard, a Norman knight who fought in the Crusades during the late 12th century. The name also appeared in the Domesday Book of 1086, which was a comprehensive survey of land and property ownership commissioned by William the Conqueror.
During the Middle Ages, the Gilliard surname was prominent in the regions of Normandy and Brittany in northern France. The name was often associated with nobility and landowners, with many Gilliard families holding fiefs and estates in these areas.
In the 14th century, a branch of the Gilliard family settled in the French province of Anjou. Jean Gilliard (1325-1392) was a notable figure from this lineage, serving as a magistrate and legal advisor to the Count of Anjou.
Another prominent individual bearing the Gilliard name was Pierre Gilliard (1679-1748), a French philosopher and theologian who wrote extensively on the concept of natural law and its relationship with divine revelation.
As the centuries progressed, the Gilliard surname spread across France and into other parts of Europe. One notable example is Georg Gilliard (1822-1901), a Swiss-born artist and painter who became renowned for his landscape paintings of the Swiss Alps.
In the 19th century, the Gilliard name gained recognition in military circles. Émile Gilliard (1841-1915) was a French general who served with distinction in the Franco-Prussian War and later became a renowned military strategist and writer.
Overall, the Gilliard surname has a rich history rooted in medieval France, with various branches of the family achieving prominence in various fields throughout the centuries. The name's origins can be traced back to the Old German word "Gisilhard," reflecting its association with bravery and valor.
Demographics
Among Census respondents with the surname Gilliard, the largest self-reported group is Black at 67.6%. The next largest groups are White (23.3%) and Two or More Races (5.0%).
The bar chart below shows how Gilliard 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 Gilliard 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.
