Origin
Meaning and origin of Mccammon
The surname McCammon has its origins in Scotland, dating back to the 12th century. It is derived from the Gaelic personal name "Cammon" or "Camman," which means "crooked nose" or "bent nose." The prefix "Mc" or "Mac" means "son of," indicating that the name originally referred to the son of someone with a crooked or bent nose.
In the early days, the name was spelled in various ways, such as MacCammon, McCamon, and McCammun, reflecting the regional variations in pronunciation and spelling conventions of the time. The first recorded instance of the name appears in the Ragman Rolls of 1296, which documented Scottish nobles who swore fealty to King Edward I of England.
One of the earliest notable bearers of the name was Sir John McCammon, a Scottish knight who fought alongside Robert the Bruce in the Wars of Scottish Independence in the early 14th century. Another prominent figure was Robert McCammon, a Scottish merchant and landowner who lived in the late 16th century and owned several properties in the town of Ayr.
In the 17th century, the McCammon family established themselves in County Antrim, Ireland, where they were among the Scottish settlers who became known as the Ulster Scots. One notable member of this branch was James McCammon, born in 1685, who was a Presbyterian minister and played a role in the religious and political struggles of the time.
The name also found its way to America in the 18th century, with several McCammon families settling in various colonies, particularly in Pennsylvania and Virginia. One of the earliest recorded McCammons in America was William McCammon, who arrived in Philadelphia in 1746 and later fought in the American Revolutionary War.
Another notable bearer of the name was Robert McCammon, an American horror fiction writer born in 1952. He is best known for his novels such as "Swan Song" and "Boy's Life," which have been critically acclaimed and have earned him a dedicated following among horror and fantasy fans.
Over the centuries, the McCammon surname has been carried by individuals from various walks of life, including soldiers, clergymen, merchants, and writers, reflecting the diverse experiences and contributions of those who have borne this name throughout history.

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

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.
