Origin
The surname Wiltz has its origins in Germany, and it is believed to have emerged during the medieval period, around the 13th or 14th century. The name is thought to be derived from the German word "wilz," which means "wild" or "untamed." This could suggest that the name was initially given to someone who lived in a remote or wilderness area.
One of the earliest recorded instances of the name Wiltz can be found in the Codex Diplomaticus Anhaltinus, a collection of historical documents from the Anhalt region of Germany, dating back to the 12th century. In this collection, there is a reference to a person named "Wilcze," which is believed to be an earlier spelling variation of the surname Wiltz.
Another significant historical reference to the name Wiltz can be found in the Annales Fuldenses, a chronicle of events from the Frankish Empire, compiled by monks at the Fulda monastery in Germany. This chronicle mentions a nobleman named "Wiltzius" who lived during the 9th century.
One of the earliest documented individuals with the surname Wiltz was Johann Wiltz, a German scholar and theologian who lived in the 15th century (c. 1420-1490). He was known for his contributions to the study of canon law and served as a professor at the University of Leipzig.
In the 16th century, there was a notable figure named Hans Wiltz (c. 1510-1580), who was a German military commander and diplomat. He played a crucial role in the events surrounding the Schmalkaldic War, a conflict between the Protestant princes and the Catholic Holy Roman Emperor Charles V.
Another prominent individual with the surname Wiltz was Friedrich Wiltz (1772-1854), a German-born military officer who served in the Prussian army. He fought in the Napoleonic Wars and was awarded the prestigious Pour le Mérite order for his bravery and leadership on the battlefield.
During the 19th century, the surname Wiltz was also found in the United States. One notable American with this surname was John Wiltz (1828-1902), a politician and lawyer from Louisiana who served as a member of the Louisiana State Senate and the United States House of Representatives.
The surname Wiltz has also been associated with several place names, particularly in Germany and Luxembourg. For instance, the town of Wiltz in northern Luxembourg is believed to have derived its name from the surname, possibly indicating that it was founded or inhabited by individuals bearing this name.
Demographics
Among Census respondents with the surname Wiltz, the largest self-reported group is Black at 60.9%. The next largest groups are White (29.5%) and Hispanic (4.4%).
The bar chart below shows how Wiltz 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 Wiltz 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.
