Origin
The surname MCGUFFIE is of Scottish origin, originating in the late medieval period. It is believed to have derived from the Gaelic "Mac Dhuibhshíthe," meaning "son of the dark one" or "son of the swarthy man." This suggests that the name may have been initially a descriptive nickname referring to a person's physical appearance.
The earliest recorded spelling of the name dates back to the late 15th century, where it appeared as "McGuffok" in the Rental Book of Cupar-Angus in 1473. Other early variants include "McGuffog," "McGuffock," and "McGuffie." These variations likely stem from the name's transition from Gaelic to English and the challenges of transliterating the Gaelic spelling.
One of the earliest recorded bearers of the name was John McGuffie, who was mentioned in the Register of the Great Seal of Scotland in 1501. Another early reference is found in the Exchequer Rolls of Scotland, where a Robert McGuffok is listed in 1531.
The name has been associated with several notable individuals throughout history. One of the earliest was Sir John McGuffie (1551-1634), a Scottish landowner and member of the Scottish Parliament. In the 18th century, Alexander McGuffie (1746-1828) was a prominent Scottish minister and author.
During the 19th century, several McGuffies made significant contributions. James McGuffie (1811-1890) was a Scottish journalist and editor, while John McGuffie (1827-1905) was a Canadian lawyer and politician who served as a member of the Legislative Assembly of Ontario.
In more recent times, Alistair McGuffie (1920-2002) was a Scottish actor and writer known for his roles in films and television shows. His cousin, Ian McGuffie (1924-2018), was a Scottish footballer who played for several clubs, including Falkirk and Dunfermline Athletic.
While the name MCGUFFIE is not among the most common Scottish surnames, it has a rich history dating back to the late medieval period and has been borne by individuals from various walks of life throughout the centuries.
Demographics
Among Census respondents with the surname Mcguffie, the largest self-reported group is White at 63.1%. The next largest groups are Black (30.5%) and Two or More Races (3.5%).
The bar chart below shows how Mcguffie 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 Mcguffie surname at the time of the 2020 Census, not any inherent property of the name itself.

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 Mcguffie (2000, 2010, 2020).
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.
