Origin
The surname MACKENS is believed to have originated in Scotland, derived from the Gaelic "mac Eanruig," meaning "son of Henry." This patronymic name dates back to the 12th century, when it was common practice to identify individuals by their father's name.
One of the earliest recorded instances of the name can be found in the Ragman Rolls of 1296, which documented Scottish nobles who swore allegiance to King Edward I of England. The entry "Willelmus Makhenry" is thought to refer to an ancestor of the MACKENS family.
By the 15th century, variations of the spelling had emerged, such as MACKHENRY, MACHENRY, and MACKENRY. These variations were likely influenced by regional dialects and the phonetic interpretation of the name by scribes and record-keepers.
The MACKENS name has been associated with several notable figures throughout history. One such figure was John Mackens (c. 1530-1590), a Scottish clergyman who served as the Bishop of Ross from 1572 until his death. He played a significant role in the Scottish Reformation and was a staunch supporter of the Presbyterian church.
Another prominent individual was Sir Robert Mackens (1625-1692), a Scottish judge and landowner who served as Lord Justice Clerk, the second highest judicial position in Scotland at the time. He was known for his impartial rulings and his efforts to reform the Scottish legal system.
In the 18th century, the MACKENS name was linked to several place names in Scotland, including Mackensburgh, a small village in Renfrewshire, and Mackenshall, an estate in Ayrshire. These place names likely derived from the surname and reflected the influence of the MACKENS family in those regions.
Another notable figure was James Mackens (1784-1854), a Scottish architect who designed several prominent buildings in Edinburgh, including the Royal Scottish Academy and the National Gallery of Scotland. His work played a significant role in shaping the city's architectural landscape during the Georgian era.
Finally, in the 19th century, Sir Thomas Mackens (1825-1892) was a Scottish industrialist and philanthropist who made significant contributions to the development of the textile industry in Glasgow. He was also a prominent supporter of educational initiatives and founded the Mackens Trust, which provided scholarships to underprivileged students.
Demographics
Among Census respondents with the surname Mackens, the largest self-reported group is White at 67.2%. The next largest groups are Black (23.5%) and Two or More Races (4.2%).
The bar chart below shows how Mackens 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 Mackens 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.

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.
