Origin
The surname Knott has its origins in England and is derived from the Old English word 'cnotta', meaning a knot or a knotted cord. It was likely used initially as a descriptive nickname for someone who worked with ropes or knotted cords, perhaps a sailor or a ropemaker.
The earliest recorded instance of the Knott surname dates back to the 12th century in the Pipe Rolls of Berkshire, where a Roger Cnot is mentioned in 1195. Another early record is found in the Hundredorum Rolls of 1273, which lists a Robert Knot in Oxfordshire.
During the medieval period, the surname Knott was particularly prevalent in the counties of Derbyshire, Staffordshire, and Cheshire. Some notable early bearers of the name include John Knot, who was a member of the Parliament of England in 1399, and William Knott, a landowner in Yorkshire mentioned in the Court Rolls of 1447.
The name Knott is also connected to several place names in England, such as Knott Hill in Staffordshire and Knott Lane in Derbyshire. These place names likely derived their names from individuals with the surname Knott who lived in or owned land in those areas.
One of the earliest recorded instances of the Knott surname in the United States is that of John Knott, who arrived in Virginia in 1635. Another notable early American bearer of the name was Thomas Knott, a Quaker who settled in Pennsylvania in the late 17th century.
Throughout history, several individuals with the Knott surname have achieved notable status. These include James Proctor Knott (1830-1908), a U.S. Congressman and Governor of Kentucky, and Edward J. Knott (1799-1875), a prominent American Catholic priest and educator who founded Mount St. Mary's University in Maryland.
Other notable figures with the Knott surname include James Raffield Knott (1853-1923), an English cricketer who played for Derbyshire, and Frederic Knott (1916-2002), an American playwright best known for his play "Dial M for Murder."
Demographics
Among Census respondents with the surname Knott, the largest self-reported group is White at 79.8%. The next largest groups are Black (12.1%) and Two or More Races (3.6%).
The bar chart below shows how Knott 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 Knott 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.
