Origin
The surname Gilleland is believed to have originated in Scotland, with roots dating back to the 12th century. It is derived from the Gaelic words "gil," meaning a ravine or glen, and "lann," meaning an enclosure or church. This suggests that the name may have initially referred to someone who lived near a ravine or glen with a church or monastic settlement.
One of the earliest recorded instances of the name can be found in the Ragman Rolls of 1296, a collection of homages rendered to King Edward I of England after his conquest of Scotland. The name is listed as "Gillelande," which is likely an earlier spelling variation.
During the 13th and 14th centuries, the Gilleland family is believed to have been well-established in the Scottish Lowlands, particularly in the regions of Ayrshire and Renfrewshire. Records from this period often mention individuals with variations of the name, such as "Gillelan," "Gillelane," and "Gillaland."
In the 16th century, a notable figure named John Gilleland (c. 1520-1590) was a prominent religious leader and reformer in Scotland. He played a significant role in the establishment of the Presbyterian Church and was a close associate of John Knox.
Another prominent individual was Sir Robert Gilleland (1644-1718), a Scottish nobleman and politician who served as a member of the Parliament of Scotland and later the Parliament of Great Britain after the Acts of Union in 1707.
In the 18th century, the Gilleland name appeared in various historical records, including the Parish Registers of Ayrshire, which documented births, marriages, and deaths within the region. One such entry from 1756 mentions a William Gilleland, whose occupation is listed as a farmer.
During the 19th century, as the Scottish diaspora spread across the world, the Gilleland surname began to appear in various parts of the British Empire and beyond. One notable individual from this era was James Gilleland (1801-1878), a Scottish-born Australian explorer and surveyor who played a crucial role in mapping the interior of the continent.
Another significant figure was Mary Gilleland (1867-1945), a Scottish suffragette and activist who campaigned tirelessly for women's rights and social reform. She was a prominent figure in the Women's Social and Political Union and was arrested several times for her involvement in protests and civil disobedience.
Demographics
Among Census respondents with the surname Gilleland, the largest self-reported group is White at 91.9%. The next largest groups are Hispanic (3.1%) and Two or More Races (2.5%).
The bar chart below shows how Gilleland 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 Gilleland 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.
