Origin
The surname McGill has its origins in Ireland and Scotland, where it first appeared in the 12th century. It is derived from the Gaelic personal name "Gill" or "Gille," meaning "servant" or "youth," combined with the prefix "Mac," meaning "son of." This suggests that the name originally referred to the son of someone named Gill.
The earliest recorded instances of the name can be found in Scottish and Irish historical records from the 13th and 14th centuries. One notable example is the mention of "Gillemor McGill" in the Exchequer Rolls of Scotland in 1264. The surname is also found in various forms, such as "M'Gill," "McGyll," and "Makgill," reflecting regional variations in spelling and pronunciation.
Several historical figures have borne the surname McGill. One of the earliest was Sir James McGill (1744-1813), a Scottish-born merchant and philanthropist who was a prominent figure in Montreal, Canada. He bequeathed a significant portion of his estate to establish McGill University, one of Canada's most prestigious institutions of higher learning.
Another noteworthy individual was John McGill (1809-1890), an Irish-born civil engineer who played a significant role in the construction of the Erie Canal and other major infrastructure projects in the United States during the 19th century.
In Scotland, the McGill family had a strong presence in Ayrshire, where they held lands and were involved in local affairs. One notable member was Sir David McGill (1549-1628), a Scottish courtier and diplomat who served under King James VI and I.
In Ireland, the McGill surname was particularly prevalent in County Down, where it is believed to have originated. One prominent figure was Patrick McGill (1801-1891), an Irish Catholic priest and educator who established several schools and played a key role in promoting education in the region.
While the surname McGill has its roots in the British Isles, it has since spread to various parts of the world through migration and immigration. Notable individuals with this surname have made contributions in fields such as education, engineering, business, and politics, leaving a lasting legacy associated with the name.
Demographics
Among Census respondents with the surname Mcgill, the largest self-reported group is White at 65.2%. The next largest groups are Black (26.2%) and Two or More Races (4.0%).
The bar chart below shows how Mcgill 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 Mcgill 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.
