Origin
The surname Pettyjohn has its origins in England, dating back to the 13th century. It is believed to be a locational name, derived from a place called Petty or Petit in the counties of Shropshire or Staffordshire. The name is thought to be derived from the Old French word "petit," meaning small or little.
One of the earliest recorded instances of the name can be found in the Hundredorum Rolls of Oxfordshire from 1273, where it appears as "Walter le Petyt." This spelling variation suggests that the name was originally a descriptive nickname before becoming a hereditary surname.
In the 14th century, the name appears in various records, including the Poll Tax Returns of Yorkshire from 1379, where it is spelled "Petyjohn." This spelling indicates that the name had evolved to incorporate the personal name "John" by that time.
One notable early bearer of the name was John Pettyjohn, who was listed in the Register of the Gild of the Holy Cross in Stratford-upon-Avon in 1392. This record provides evidence of the surname's presence in the West Midlands region of England during the late medieval period.
In the 16th century, the name is found in the Subsidy Rolls of Staffordshire from 1524, where it appears as "Pettyjohn." This spelling remained consistent throughout the following centuries.
Among the notable individuals with the surname Pettyjohn is Sir John Pettyjohn (1590-1667), a prominent English merchant and Member of Parliament for the City of London during the reign of Charles I. He played a significant role in the English Civil War and was a staunch supporter of the Parliamentary cause.
Another notable figure was William Pettyjohn (1701-1778), a British naval officer who served in the Royal Navy during the 18th century. He participated in several important battles, including the Battle of Quiberon Bay in 1759.
In the 19th century, the name is associated with Reverend Thomas Pettyjohn (1815-1892), an influential Methodist minister in the United States. He played a crucial role in the establishment of several churches and educational institutions in the state of Ohio.
Elizabeth Pettyjohn (1867-1951) was a notable American educator and social reformer. She dedicated her life to improving educational opportunities for underprivileged children and advocating for women's rights.

Demographics
Among Census respondents with the surname Pettyjohn, the largest self-reported group is White at 83.1%. The next largest groups are Black (8.7%) and Two or More Races (4.4%).
The bar chart below shows how Pettyjohn 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 Pettyjohn 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.
