Origin
The surname DENING is believed to have originated in England during the medieval period. It is likely derived from the Old English word "denu" or "dene," which means a valley or a hollow. This suggests that the earliest bearers of this name may have lived in or near a valley or a low-lying area.
The name can be traced back to the 13th century, with records showing variations such as "de la Dene" and "atte Dene." These early spellings indicate that the name was initially a locative surname, referring to a person's place of residence or origin.
One of the earliest recorded instances of the DENING surname can be found in the Subsidy Rolls of Sussex, dated 1327. In these records, a certain Richard de la Dene is listed as a taxpayer in the county.
During the 14th century, the surname underwent further changes in spelling, with variations like "Denyng" and "Denynge" appearing in various historical documents. This was a common occurrence during that time, as spellings were often influenced by regional dialects and the personal preferences of scribes.
In the 15th century, the DENING surname is documented in the Court Rolls of Wakefield, Yorkshire. A William Denyng is recorded as holding land in the area around 1440.
One notable bearer of the DENING surname was John Dening, a 16th-century English clergyman and theologian. Born in 1509, he was a prominent figure in the Anglican church and served as the Archdeacon of Rochester from 1557 until his death in 1581.
Another individual of historical significance was Thomas Dening, a 17th-century English landowner and member of the gentry. He was born in 1625 and owned estates in Berkshire, where he lived until his passing in 1702.
In the 18th century, the DENING surname gained further prominence with the birth of James Dening (1738-1814), a British naval officer who served during the American Revolutionary War and the Napoleonic Wars.
During the 19th century, the DENING surname was carried by William Dening (1801-1879), a British architect who designed several notable buildings in London, including the Church of St. Mary Magdalene in Paddington.
Another notable figure was Sir Henry Dening (1865-1945), a British judge and legal scholar who served as a Lord Justice of Appeal and played a significant role in shaping English contract law.
Demographics
Among Census respondents with the surname Dening, the largest self-reported group is White at 91.5%. The next largest groups are Two or More Races (6.0%) and American Indian/Alaska Native (1.7%).
The bar chart below shows how Dening 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 Dening surname at the time of the 2020 Census, not any inherent property of the name itself.
