The surname McWhirter is of Scottish origin, derived from the Gaelic personal name Dhuibhshíth, meaning "dark" or "swarthy one". The prefix "Mc" or "Mac" means "son of" in Gaelic, indicating a patronymic surname.
The McWhirter name can be traced back to the 12th century in the region of Ayrshire, Scotland. It is believed to have originated as a descriptive nickname for someone with a dark complexion or hair color.
One of the earliest recorded instances of the name McWhirter appears in the Ragman Rolls of 1296, a collection of homage rolls documenting Scottish landowners who swore fealty to King Edward I of England. The name is listed as "Gillemor McWhyter".
In the 15th century, variations of the spelling included McWhytre, McQuiter, and McQuhiter, reflecting the regional dialects and pronunciation variations at the time. The name was particularly prevalent in the parishes of Kilmarnock and Loudoun in Ayrshire.
A notable historical figure bearing the McWhirter surname was John McWhirter (1837-1926), a renowned Scottish landscape painter who was elected a member of the Royal Scottish Academy in 1892. He is known for his vivid depictions of the Scottish Highlands and coastal scenes.
Another prominent individual was Alexander McWhirter (1895-1979), a Canadian politician and lawyer who served as Speaker of the House of Commons of Canada from 1953 to 1957.
In the literary world, George McWhirter (1839-1907) was a Scottish poet and journalist who wrote under the pen name "Lachlann Mor". He was known for his works celebrating the Scottish Highlands and its people.
Robert McWhirter (1859-1935) was a Scottish inventor and engineer who developed the first successful pneumatic tire for bicycles, patenting his design in 1888.
Lastly, Dorothy McWhirter (1905-1985) was a British author and playwright best known for her children's book "The Silver Brumby", which was later adapted into a film in 1993.
Demographics

The bar chart below shows how Mcwhirter 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 Mcwhirter 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.
