Origin
The surname Wiuff likely originates from Denmark, with its roots tracing back to medieval times. Denmark, as part of the Scandinavian region, has a rich history of surnames that evolved from patronymic practices, geographical locations, and occupations. Wiuff is not among the most common surnames, which suggests it may have regional specificity or origins in smaller communities.
The name Wiuff may have derived from a combination of medieval Danish words or could be a variation of similar-sounding names from the period. The etymology could be linked to landscape features or occupations, though specific ancient words that it derives from are difficult to pinpoint precisely due to the scarcity of historical records. Similar spellings could include variations like Wiuf or Wuff, showing the fluid nature of surname spelling in historical records.
One of the earliest records where the name Wiuff appears is in local Danish church registries from the 1600s. These registries were kept by local parishes to document baptisms, marriages, and burials, which were essential records of the community's history. In one such registry from the town of Aarhus in the year 1654, there is mention of a Hans Wiuff, a local farmer. This suggests the name was already being used as a hereditary surname by the mid-17th century.
Further historical references include a soldier named Anders Wiuff who served in the Danish-Norwegian army during the Great Northern War (1700-1721). His service records from 1707 mention his participation in various battles, providing insight into the use and spread of the surname among different social classes in Danish society.
In the 18th century, another notable bearer of the surname was Jens Wiuff, born in 1732, who was known for his role as a merchant in the thriving coastal trade of Denmark. His trade dealings, recorded in maritime logs and merchant guild records of Copenhagen, suggest the name had a presence in commercial and urban contexts.
By the 19th century, a significant figure with the surname was Peter Wiuff, a notable landowner and farmer in Jutland, Denmark, born in 1820 and died in 1889. Historical agricultural journals and local historical societies’ publications frequently mention him, indicating the name's continued association with land and agriculture across generations.
Finally, historian records from the early 20th century mention Karen Wiuff, who was born in 1875 and became one of Denmark’s pioneering women in the field of education. She played a significant role in the establishment of several schools in rural Denmark and contributed to educational reforms, making her a significant historical figure bearing this unique surname.
In summary, the surname Wiuff has its roots deeply embedded in Danish history, evolving over centuries from likely regional origins to being borne by individuals who contributed to various facets of Danish society, from agriculture to military service, and education. The surname’s journey through time paints a fascinating picture of its role and significance in Denmark’s historical tapestry.
Demographics
Among Census respondents with the surname Wiuff, the largest self-reported group is White at 94.8%. The next largest groups are Hispanic (2.6%) and Two or More Races (2.6%).

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