Origin
The surname McQuilken is of Scottish origin and is believed to have originated in the 16th century. It is thought to be a variant of the Scottish surname McQuillan, which is derived from the Gaelic personal name "MacCuilleanáin," meaning "son of the little lad."
The name McQuilken is closely associated with the Scottish county of Ayrshire, particularly the town of Kilwinning. Some of the earliest recorded instances of the surname can be found in parish records from this region, with references to individuals such as John McQuilken, who was born in Kilwinning in 1598.
In the 17th century, the McQuilken name appeared in various historical documents, including the Register of the Privy Council of Scotland, which mentions a William McQuilken who was involved in a legal dispute over land ownership in 1647.
One notable individual with the surname McQuilken was Robert McQuilken (1695-1772), a Scottish clergyman and author who served as the minister of Cadder Parish Church in Lanarkshire. His published works include a historical account of the parish and a collection of sermons.
Another prominent figure was Sir James McQuilken (1789-1856), a Scottish businessman and philanthropist who made his fortune in the textile industry. He was knighted for his contributions to the city of Glasgow and funded the construction of several churches and schools in the area.
In the 19th century, the McQuilken surname began to spread beyond Scotland, with individuals bearing this name emigrating to other parts of the United Kingdom and North America. One such individual was John McQuilken (1822-1897), a Scottish-born farmer who settled in Ontario, Canada, and played a significant role in the development of the local agricultural community.
Another notable figure from this period was William McQuilken (1856-1924), an Irish-born architect who worked in London and was responsible for designing several notable buildings, including the Royal Academy of Music and the City of London School.
While the McQuilken surname is not as common today as some other Scottish surnames, it has a rich history and has been borne by individuals who have made significant contributions in various fields, from religion and literature to business and architecture.
Demographics

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 Mcquilken 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.
