Origin
The surname Amsbary is believed to have originated in the region of Northamptonshire, England during the medieval period. It is thought to be a locational surname derived from the old English place name "Annesborough" or a similar spelling variation.
One of the earliest recorded instances of the surname can be found in the Pipe Rolls of Northamptonshire from the year 1198, which listed one William de Annesburgh. This suggests that the name was already in use by the late 12th century.
In the 13th century, the surname appeared in various forms such as Amesburi, Amesbury, and Amsbury, reflecting the evolving spelling variations common during that era. The name is believed to have connections to the town of Amesbury in Wiltshire, which was originally known as Annesburh or Ambresbury.
A notable early bearer of the surname was Sir John Amesbury, a knight who served under King Edward III during the Hundred Years' War in the 14th century. He was recorded as participating in the Battle of Crécy in 1346.
During the 16th century, the surname appeared in various parish records across Northamptonshire and neighboring counties. One example is the christening of Robert Amsbury in the parish of Towcester in 1578.
In the 17th century, the surname continued to be found in various parts of England, with examples including the marriage of Thomas Amsbery and Elizabeth Browne in Sulgrave, Northamptonshire in 1642.
Another notable figure with this surname was Robert Amsbary, a merchant and landowner who lived in Northampton during the late 17th century. He was recorded as owning several properties and businesses in the town.
By the 18th century, the surname had spread to other parts of the British Isles, with records showing individuals with the name Amsbury or Amsbary residing in Scotland and Ireland.
As the centuries progressed, the surname underwent various spelling variations, including Amsbery, Amesbury, Amsbury, and the modern form Amsbary. Despite these changes, the name maintained its connection to the original place name and its English origins.
Demographics

The bar chart below shows how Amsbary 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 Amsbary 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.
