Origin
The surname Gilks originated in England, with its earliest recorded instances dating back to the 13th century. It is believed to have derived from the Old English word "gilc," which referred to a ravine or a deep, narrow valley. This suggests that the name may have been initially given to someone who lived near or worked in such a geographical feature.
The Gilks name is thought to have originated in the northern counties of England, particularly in Yorkshire and Lancashire. Some of the earliest recorded instances of the name can be found in medieval tax rolls and parish records from these regions.
One notable historical reference to the Gilks name is found in the Subsidy Rolls of Lancashire, dated 1332. This document lists a "Gilbertus del Gilkes" among the taxpayers of the time. The use of the preposition "del" (from the) before the surname suggests that the name was associated with a specific location or landholding.
In the 16th century, the surname appears to have been concentrated in the Furness region of Lancashire. Records from this period show variations in spelling, such as "Gilkes," "Gylkes," and "Gylks."
Notable individuals with the surname Gilks throughout history include:
1. John Gilks (c. 1585-1657), an English clergyman and theologian who served as the rector of Ashton-under-Lyne in Lancashire.
2. William Gilks (1732-1811), a British politician and landowner who served as a Member of Parliament for Clitheroe from 1784 to 1790.
3. Thomas Gilks (1833-1912), a prominent English industrialist and founder of the Gilks Engineering Company in Manchester.
4. Mary Gilks (1865-1947), a British suffragist and activist who campaigned for women's rights and participated in the Suffragette movement.
5. Walter Gilks (1891-1970), an English cricketer who played first-class cricket for Lancashire County Cricket Club in the early 20th century.
While the Gilks name has been present in historical records for centuries, it is important to note that its prevalence and geographical distribution may have shifted over time due to migration and other factors.
Demographics
Among Census respondents with the surname Gilks, the largest self-reported group is White at 89.1%. The next largest groups are Hispanic (5.5%) and Black (3.6%).
The bar chart below shows how Gilks 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 Gilks 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.
