Origin
The surname Douglass originated in Scotland in the 12th century and is derived from the Gaelic words "dubh" meaning "dark" and "glas" meaning "stream" or "water." It refers to the Douglas River in Lanarkshire, Scotland. The earliest recorded spelling of the name was "Douglasdale" in the 12th century.
The Douglas family played a significant role in Scottish history, with the first recorded bearer of the name being Sir William Douglas, who was granted the lands of Douglas in Lanarkshire in the early 12th century. The family later became one of the most powerful noble families in Scotland, with members holding influential positions such as Earls of Douglas, Dukes of Touraine, and Lords of Liddesdale.
One of the earliest historical references to the name can be found in the Ragman Rolls of 1296, which recorded the names of Scottish nobles who swore allegiance to King Edward I of England. Several Douglases are listed in this document, including Sir William Douglas, the Governor of Berwick Castle.
In the 14th century, Sir James Douglas, also known as the "Black Douglas," was a renowned Scottish warrior and companion of Robert the Bruce. He played a crucial role in the Scottish Wars of Independence and was entrusted with the task of carrying the heart of Robert the Bruce to the Holy Land after the king's death in 1329.
Another notable figure in the history of the Douglass name was Archibald Douglas, Earl of Angus, who lived from 1489 to 1557. He was a prominent Scottish nobleman and played a significant role in the political and military affairs of Scotland during the reigns of James IV and James V.
In the United States, the spelling variation "Douglass" became more common, particularly among African Americans, due to the influence of abolitionist and writer Frederick Douglass (1818-1895). He adopted the additional "s" to distinguish himself from his former enslaver and took the name as a symbol of his newfound freedom.
Other notable individuals with the surname Douglass include Paul Douglass (1835-1905), a Union Army soldier and Medal of Honor recipient during the American Civil War, and Andrew Ellicott Douglass (1867-1962), an American astronomer and pioneer in the field of dendrochronology.
Demographics
Among Census respondents with the surname Douglass, the largest self-reported group is White at 80.1%. The next largest groups are Black (11.5%) and Two or More Races (3.8%).
The bar chart below shows how Douglass 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 Douglass 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.
