Origin
The surname GAMMON is of English origin, with records dating back to the late 12th century. It is believed to have derived from the Old English word "gamen," which means "game" or "sport." This suggests that the name may have initially been given as a nickname to someone who enjoyed games or had a playful nature.
The earliest known record of the GAMMON surname appears in the Pipe Rolls of Lincolnshire in 1195, where a certain Walter Gamun is mentioned. This early spelling variation "Gamun" highlights the evolution of the name over time.
In the 13th century, the GAMMON surname is found in various records, including the Hundredorum Rolls of 1273, which list a Richard Gamun in Oxfordshire. This indicates that the name had spread to different regions of England by that time.
During the 14th century, the GAMMON surname gained prominence, with notable individuals like John Gammon, a landowner in Somerset mentioned in the Lay Subsidy Rolls of 1327. Additionally, the Placita de Quo Warranto records from 1346 mention a Richard Gammon in Hertfordshire.
One of the earliest known recorded instances of the GAMMON surname in its modern spelling can be found in the Feet of Fines records from Staffordshire in 1430, which reference a John Gammon.
Notable historical figures with the GAMMON surname include:
1. William Gammon (c. 1490 - 1549), an English churchman who served as the Bishop of Norwich from 1539 until his death.

4. Bartholomew Gammon (1677 - 1732), an English architect and surveyor who worked on several notable buildings in London.
5. William Gammon (1788 - 1864), an English cricketer who played for Kent and was considered one of the leading batsmen of his time.

Demographics
Among Census respondents with the surname Gammon, the largest self-reported group is White at 85.2%. The next largest groups are Black (7.0%) and Two or More Races (3.3%).
The bar chart below shows how Gammon 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 Gammon 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.
