Origin
The surname Werren is believed to have originated in Switzerland, specifically in the canton of Bern, during the 16th century. It is derived from the Old Swiss German word "werre," which means "strife" or "conflict," suggesting that the name may have been given to someone who was involved in some sort of dispute or quarrel.
One of the earliest recorded instances of the name Werren can be found in the parish records of the village of Wilderswil, near Interlaken, dating back to the late 1500s. The name was also mentioned in the Burgerbuch, a register of citizens, in the city of Bern in the early 1600s.
In the 17th century, the Werren family seemed to have spread beyond the Bernese region. Historical records show a Johann Werren who lived in the town of Zug in the 1670s, and a Hans Werren who was a farmer in the village of Eschenbach, in the canton of St. Gallen, in the late 1600s.
As the Werren family continued to grow and expand throughout Switzerland, some of its members achieved notable positions. For instance, Jakob Werren (1640-1718) was a prominent merchant and city councilor in Bern, while his grandson, Samuel Werren (1685-1756), was a respected theologian and pastor in the nearby town of Thun.
In the 19th century, the name Werren started to appear in other parts of Europe as well. One notable figure was Friedrich Werren (1808-1891), a German-born painter and illustrator who was known for his landscapes and works depicting rural life in the Black Forest region.
Another individual of note was Theodor Werren (1842-1913), a Swiss entrepreneur who made his fortune in the textile industry and was a major philanthropist in his hometown of St. Gallen. His legacy includes the Werren Foundation, which still supports charitable causes in the region today.
While the surname Werren may not be as common as some others, it has a rich history that spans several centuries and various regions of Switzerland and beyond. From its possible origins as a descriptor of a person's temperament to its association with successful individuals in fields ranging from commerce to the arts, the name Werren has left its mark on the cultural and social fabric of the areas where it has taken root.
Demographics
Among Census respondents with the surname Werren, the largest self-reported group is White at 90.4%. The next largest groups are Two or More Races (6.1%) and Black (2.6%).
The bar chart below shows how Werren 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 Werren 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.
