Origin
Meaning and origin of Jarmon
The surname Jarmon has its roots in England, and it is believed to have originated during the Middle Ages, specifically in the 12th or 13th century. The name is thought to be derived from the Old English personal name "Garmund," which means "spear protector."
One of the earliest recorded instances of the name Jarmon can be traced back to the Domesday Book of 1086, where it appears as "Germund." This historical document, commissioned by William the Conqueror, provides a record of landowners and their holdings throughout England.
Over time, the name underwent various spelling variations, such as Jarman, Jarmyn, and Jarmain, before settling on the modern spelling of Jarmon. These variations were often influenced by local dialects and the preferences of scribes who recorded the name.
In the 13th century, a notable figure bearing the name Jarmon was William Jarman, who served as a member of the Parliament of England during the reign of King Edward I (1272-1307).
During the 16th century, the name Jarmon was associated with several prominent individuals, including John Jarman (c. 1560-1622), an English clergyman and author who wrote extensively on religious subjects.
Another notable figure was Thomas Jarman (1673-1738), an English architect and surveyor who designed several churches and buildings in London and the surrounding areas.
In the 18th century, the Jarmon surname gained further prominence with the birth of John Jarman (1733-1808), a British naval officer who served in the Royal Navy during the American Revolutionary War and the Napoleonic Wars.
In the 19th century, a significant figure with the surname Jarmon was Alfred Jarman (1825-1892), an English architect and surveyor who designed numerous churches and public buildings in Norfolk and Suffolk.
Throughout history, the Jarmon surname has also been associated with various place names, such as Jarmyn Hill in Lincolnshire, which was likely named after an early bearer of the name who resided in or owned land in that area.

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 Jarmon surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Jarmon (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
