Origin
The surname McClary is believed to have originated in Scotland, specifically in the Scottish Highlands. It is derived from the Gaelic mac Labhruinn, meaning "son of the talkative one" or "son of the babbler." The name's earliest recorded spelling dates back to the late 12th century.
In the early 13th century, a charter from the reign of King Alexander II of Scotland (1198-1249) mentions a "Malcolm M'Clarene." This is thought to be one of the earliest written references to the McClary name.
The McClary name has also been found in various ancient Scottish records, including the Exchequer Rolls of Scotland from the late 13th and early 14th centuries. These rolls document tax payments made by individuals with the surname, indicating their presence in different regions of Scotland during that time.
One notable individual with the McClary surname was Sir Robert McClary, who lived in the 15th century. He was a Scottish knight and landowner, and his name appears in several charters and legal documents from that period.
In the 16th century, a John McClary (born around 1530) was a prominent merchant and burgess (a citizen of a burgh or town) in Aberdeen, Scotland. He is mentioned in various town records and is believed to have been a successful and influential figure in the local community.
Another noteworthy McClary was William McClary (1734-1801), a Scottish-born American soldier who fought in the American Revolutionary War. He served as a lieutenant colonel in the Continental Army and participated in several major battles, including the Battle of Bunker Hill.
In the 19th century, Sir Thomas McClary (1817-1892) was a Scottish businessman and politician who served as Lord Provost (mayor) of Edinburgh from 1874 to 1877. He was also involved in various charitable organizations and was knighted for his services to the city.
The McClary surname has also been found in various place names throughout Scotland, such as McClary's Burn (a small stream) in Ayrshire and McClary's Hill in Aberdeenshire. These place names likely originated from individuals with the McClary surname who lived or owned land in those areas.
Demographics
Among Census respondents with the surname Mcclary, the largest self-reported group is White at 53.6%. The next largest groups are Black (38.9%) and Two or More Races (4.1%).
The bar chart below shows how Mcclary 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 Mcclary 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.
