The earliest recorded instance of the name Fergus dates back to the 12th century.

The manuscript mentions a man named Fergus, who was a cleric in the monastery of Deer in Aberdeenshire.
In the 13th century, the name Fergus appeared in the Ragman Rolls, a series of historical documents that recorded the submission of Scottish nobles to King Edward I of England. One of the signatories was a certain Fergus de Ardrossan, a landholder from Ayrshire.
The Fergus surname has also been linked to several notable figures throughout history. One of the most famous was Fergus Mor MacErc, a legendary king of Dál Riata who is said to have lived in the 6th century AD. According to tradition, he was the first king of Scottish descent to rule in Scotland.
Another notable Fergus was Fergus of Galloway, a 12th-century prince who ruled over the region of Galloway in southwestern Scotland. He is mentioned in various historical chronicles and is known for his involvement in the political struggles of the time.
In the 15th century, a man named Fergus MacDowall was the chief of the Clan MacDougall, a prominent Scottish clan based in Argyll. He played a significant role in the Wars of Scottish Independence against the English.
One of the earliest recorded instances of the Fergus surname in North America dates back to the 18th century. In 1773, a man named John Fergus emigrated from Scotland to Virginia, where he became a prominent landowner and civic leader.
The Fergus surname has also been associated with several place names in Scotland. The town of Ferguslie in Renfrewshire is believed to have been named after a person named Fergus, while the village of Fergushill in Ayrshire may have a similar origin.
Demographics
Among Census respondents with the surname Fergus, the largest self-reported group is White at 77.9%. The next largest groups are Black (12.3%) and Hispanic (4.8%).
The bar chart below shows how Fergus 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 Fergus 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 Fergus (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.
