Origin
The surname Hartshorn is of English origin, deriving from the Old English words "heorot" meaning "hart" or male red deer, and "horn". It likely originated as a descriptive name for someone who worked with or traded in the antlers of deer, which were used to make various items like handles, combs, and powders for medicinal purposes.
The name can be traced back to the 13th century, with one of the earliest recorded instances being Robert Hertshorn, mentioned in the Worcestershire Assize Rolls of 1221. The surname also appeared in various forms like Herteshorn, Hertishorne, and Hertshorne in medieval records across counties like Staffordshire, Berkshire, and Warwickshire.
In the renowned Domesday Book of 1086, there is a reference to a place called "Hertesburne" in Dorset, which may have been an early spelling variation of the name or a location from which the surname derived its origins.
Notable individuals with the surname Hartshorn throughout history include Thomas Hartshorn (c.1530-1585), an English churchman who served as the Bishop of Norwich, and John Hartshorn (1650-1718), a prominent Quaker minister and author from Ashbourne, Derbyshire.
In the 17th century, William Hartshorn (1637-1683) was a renowned English mathematician and astronomer who made significant contributions to the study of celestial mechanics and the calculation of planetary orbits.
Moving forward, Elizabeth Hartshorn (1780-1854) was a British author and educator who wrote several influential works on early childhood education and the treatment of children in educational settings.
Lastly, George Hartshorn (1822-1898) was an American politician and businessman who served as the Mayor of Boston, Massachusetts, from 1876 to 1878, during a period of rapid growth and development in the city.

The bar chart below shows how Hartshorn 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 Hartshorn 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.
