Origin
The surname DIEW has its origins in England, emerging during the late medieval period around the 14th century. It is believed to be derived from the Old English word "diewhol," which translates to "precious" or "valuable." This suggests that the name may have been initially bestowed upon someone who was highly regarded or esteemed within their community.
One of the earliest recorded instances of the DIEW surname can be found in the Subsidy Rolls of Worcestershire, dated 1327, where a certain John Diewe is mentioned as a taxpayer. This entry provides valuable insight into the early spelling variations of the name, which often fluctuated due to inconsistent record-keeping practices of the time.
In the late 15th century, the DIEW surname appears in the Paston Letters, a collection of historical correspondence between members of the influential Paston family. The letters mention a Richard Diew, who was a servant in the Paston household, serving as a testament to the widespread use of the surname across various social strata during that era.
Among the notable individuals bearing the DIEW surname throughout history is Sir Thomas Diew, a prominent landowner and military commander who lived in the late 16th century. He was knighted for his valiant service during the Anglo-Spanish War and played a significant role in defending England against the Spanish Armada in 1588.
Another figure of historical importance was Elizabeth Diew (1640-1712), a renowned Quaker writer and activist who advocated for religious tolerance and women's rights. Her published works, including "A Treatise on the Inward Light" and "Reflections on the Equality of the Sexes," gained widespread recognition and influenced the Quaker community in England and the American colonies.
In the 18th century, the DIEW surname found its way into the literary world through the works of novelist and playwright William Diew (1725-1789). His most notable work, "The Trials of Virtue," a satirical play commenting on societal norms, was widely acclaimed and performed throughout England during his lifetime.
Additionally, the DIEW surname can be traced back to the village of Dewsbury in West Yorkshire, which was once known as "Diewsbury" in its earlier spelling. This connection suggests that some bearers of the surname may have originated from or resided in this area, further solidifying the name's English roots.
Demographics
Among Census respondents with the surname Diew, the largest self-reported group is Black at 86.3%. The next largest groups are Two or More Races (5.1%) and White (4.3%).
The bar chart below shows how Diew 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 Diew surname at the time of the 2020 Census, not any inherent property of the name itself.
