Origin
The surname Knot originated in England, with its earliest recorded examples dating back to the 13th century. It is believed to have derived from the Old English word "cnotta," which means "a knot" or "a knotted cord." This suggests that the name may have been an occupational surname given to those who worked with ropes, cords, or knots, such as sailors, fishermen, or rope-makers.
In the Hundred Rolls of 1273, there are references to individuals with the surname Knot, including William Knot and Robert Knot. The Subsidy Rolls of Worcestershire from 1327 also mention a John Knot. These early records indicate that the name was established in various parts of England by the 14th century.
The Knot surname is found in various place names throughout England, such as Knottingley in West Yorkshire, which was originally recorded as "Cnotingeleia" in the Domesday Book of 1086. This further suggests the ancient roots of the name and its connection to knots or knotted cords.
One notable individual with the surname Knot was Edward Knott (1582-1655), an English Jesuit priest and controversialist. He was known for his writings defending the Catholic faith during the English Reformation.
Another prominent figure was Robert Knott (1599-1679), an English lawyer and politician who served as a Member of Parliament for St Germans in Cornwall during the 17th century.
In the 18th century, John Knott (1736-1811) was a respected English surgeon and medical writer. He served as the President of the Royal College of Surgeons in London and published several works on surgical techniques.
Sir James Knott (1858-1931) was a notable British engineer and industrialist. He played a significant role in the development of the British shipbuilding industry and was knighted for his contributions.
Lastly, Cargill Gilston Knott (1856-1922) was a Scottish physicist and mathematician. He made significant contributions to the study of electromagnetism and was elected a Fellow of the Royal Society in 1892.
These examples demonstrate the long-standing presence of the Knot surname in various fields, from religion and politics to medicine, engineering, and academia, further solidifying its historical significance in England and beyond.
Demographics
Among Census respondents with the surname Knot, the largest self-reported group is White at 70.9%. The next largest groups are Black (16.2%) and Hispanic (6.0%).
The bar chart below shows how Knot 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 Knot 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.
