Origin
The surname Tonsor is an occupational name that originated in medieval England, derived from the Anglo-Norman French word "tonsour," meaning a barber or hair-cutter. This name likely emerged in the late 12th or early 13th century, when surnames began to become hereditary in Europe.
The earliest known record of the name Tonsor dates back to the late 13th century, with a John le Tonsur appearing in the Hundred Rolls of Oxfordshire in 1279. This suggests that the name was already established in parts of England by that time.
During the Middle Ages, barbers played a crucial role in medieval society, not only cutting hair but also performing minor surgical procedures and tooth extractions. As such, the Tonsor name would have been associated with this skilled trade, and those bearing the name were likely members of a respected guild or profession.
One notable early bearer of the name was Robert Tonsor, a barber-surgeon who lived in London in the late 14th century. He is mentioned in the Court of Aldermen records from 1384, indicating his standing within the city's guild system.
In the 15th century, the name appeared with various spellings, including Tonsour, Tonsor, and Tonsour, reflecting the fluid nature of surname spellings during that era. For example, a John Tonsour is recorded in the Register of the Gild of the Holy Cross in Stratford-upon-Avon in 1427.
The Tonsor surname also has connections to certain place names in England, such as Tonsover in Staffordshire and Tonsure in Hertfordshire, suggesting that some bearers of the name may have originated from or lived in these areas.
Other notable historical figures with the Tonsor surname include:
1. William Tonsor (c. 1500-1570), an English clergyman and scholar who served as the Dean of Canterbury Cathedral.
2. Jacob Tonsor (1655-1736), a Dutch bookseller and publisher who established the famous Tonsor publishing house in Amsterdam.
3. Jacques Tonsor (1701-1768), a French engraver and publisher who continued the Tonsor publishing legacy in Paris.
4. John Tonsor (1715-1797), an English playwright and author, best known for his satirical works.
5. Michael Tonsor (1883-1964), an American historian and political philosopher who taught at the University of Chicago.
While the surname Tonsor is not among the most common surnames today, its history reflects the importance of skilled trades and professions in medieval and early modern Europe, as well as the lasting impact of occupational surnames on our understanding of past societies.
Demographics
Among Census respondents with the surname Tonsor, the largest self-reported group is White at 95.6%. The next largest groups are Two or More Races (3.5%) and Hispanic (0.9%).
The bar chart below shows how Tonsor 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 Tonsor 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.
