Origin
The surname MCCAMMAN is of Scottish origin, tracing its roots back to the medieval period. It is believed to have originated in the regions of Galloway and Ayrshire, where it was derived from the Gaelic personal name "Cam-shron," meaning "crooked" or "wry-nosed."
One of the earliest recorded instances of the name can be found in the Ragman Rolls of 1296, which document Scottish nobles who swore allegiance to King Edward I of England. The entry "Gilcrist M'Cambron" is thought to be an early variant spelling of the surname MCCAMMAN.
In the 16th century, the MCCAMMAN name was prevalent in the parish records of Ayrshire, particularly in the areas around the town of Maybole. A notable figure from this period was John McCamman, a merchant and landowner who lived in Maybole in the late 1500s.
During the 17th century, the surname spread to other parts of Scotland, including the Highlands and the Orkney Islands. One prominent individual from this era was Duncan McCamman, a soldier who fought in the Jacobite Uprising of 1745, supporting the cause of the exiled Stuart monarchy.
As the Scottish diaspora grew, the MCCAMMAN name also found its way to other parts of the British Isles and beyond. In the late 18th century, a family bearing the name settled in County Antrim, Ireland, where they established themselves as successful farmers and landowners.
In the 19th century, several members of the MCCAMMAN family emigrated to North America, seeking new opportunities in the expanding frontiers of the United States and Canada. One such individual was James McCamman, born in 1815 in Ayrshire, who later became a prominent businessman and civic leader in the city of Cincinnati, Ohio.
Another noteworthy figure was William McCamman, a Canadian politician and lawyer from Ontario, who served as a member of the House of Commons of Canada in the late 19th century.
Throughout its history, the MCCAMMAN surname has maintained its Scottish heritage and origins, with many variations in spelling, including McCammon, McCamon, and McCammin, among others. While the name may have evolved over time, its connection to the rugged landscapes and rich cultural traditions of Scotland remains an integral part of its identity.
Demographics
Among Census respondents with the surname Mccamman, the largest self-reported group is White at 92.4%. The next largest groups are Hispanic (2.9%) and Asian/Pacific Islander (2.9%).
The bar chart below shows how Mccamman 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 Mccamman 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.

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.
