Origin
Meaning and origin of Allmon
The surname ALLMON originated from England during the medieval period. It is derived from the Old English words "ald" meaning "old" and "mann" meaning "man." The name was likely first used as a descriptive nickname referring to an elderly or aged man.
The earliest recorded instance of the ALLMON surname dates back to the Domesday Book of 1086, where it was spelled "Aldeman." This vital historical record from the Middle Ages documented landowners and property ownership across much of England and parts of Wales shortly after the Norman Conquest.
In the 13th century, variations such as "Aldmon" and "Aldemon" began appearing in parish records and tax rolls across various counties in England, including Yorkshire, Lincolnshire, and Nottinghamshire. These early spellings reflect the regional dialects and scribal variations common during that era.
One of the earliest known bearers of the ALLMON name was Sir William Aldemon, a knight who fought alongside Richard the Lionheart during the Third Crusade in the late 12th century. He was born around 1165 in Lincolnshire and died in 1222.
Another notable figure was John Allman, a wealthy merchant and landowner from Nottinghamshire who lived during the 15th century. He was born around 1410 and died in 1486. His affluence and prominence in the region are evident from records of his land transactions and business dealings.
In the 16th century, the surname was often associated with the village of Allman's Green in Cheshire, derived from the Old English words "ald" and "mann" combined with "grene" meaning "green" or common pasture land. This suggests that some early bearers of the name may have originated from or resided in this area.
During the 17th century, notable individuals with the ALLMON surname included Robert Allman, a clergyman and author born in Yorkshire in 1610, and Thomas Allmon, a merchant and ship owner from Bristol who lived from 1635 to 1698.
Another individual of historical significance was Sir Edward Allmon, a British naval officer and explorer who was born in London in 1670. He served in the Royal Navy and is known for his voyages to the West Indies and mapping of the Caribbean islands in the early 18th century.

The bar chart below shows how Allmon 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 Allmon surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
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 Allmon (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.
