Origin
The surname Laidlow has its origins in Scotland, tracing back to the medieval period. It is believed to be a locational name derived from a place called Laidlaw, located in the Scottish Borders region. The placename itself is thought to be derived from the Old English words "læde," meaning a course or stream, and "hlaw," meaning a hill or mound.
One of the earliest recorded references to the surname Laidlow can be found in the Ragman Rolls of 1296, a historical document containing the names of Scottish landowners who swore allegiance to King Edward I of England. The name appears as "de Ledelawe," which is likely an early spelling variation.
In the 14th century, the name Laidlow appeared in various Scottish records and charters. For instance, John de Laidlaw was mentioned in a charter granted by Robert the Bruce in 1329. This suggests that the Laidlow family held lands and had a presence in Scotland during this period.
Throughout the centuries, the surname Laidlow has been associated with several notable individuals. One such person was William Laidlow (c. 1590-1659), a Scottish minister and religious writer who served as the minister of Dunning Parish in Perthshire.
Another prominent figure was Robert Laidlow (1722-1784), a Scottish architect and surveyor who designed several buildings in Edinburgh, including the Old College of the University of Edinburgh.
In the 19th century, James Laidlow (1815-1896) was a Scottish historian and author who wrote extensively about the history and antiquities of Berwickshire, a county in the Scottish Borders.
The Laidlow surname also has connections to the United States. One example is John Laidlow (1766-1847), a Scottish-born merchant and landowner who immigrated to Virginia in the late 18th century and became a prominent figure in the area.
Lastly, Robert Laidlow (1870-1949) was a Scottish-American engineer and businessman who co-founded the Laidlaw Corporation, a transportation company that operated school buses and other vehicles.
These are just a few examples of individuals with the surname Laidlow who have made significant contributions in various fields throughout history, reflecting the rich heritage and legacy associated with this Scottish surname.
Demographics
Among Census respondents with the surname Laidlow, the largest self-reported group is Black at 60.9%. The next largest groups are White (20.9%) and Hispanic (9.1%).
The bar chart below shows how Laidlow 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 Laidlow 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.
