Origin
Meaning and origin of Carrouth
The surname Carrouth has its origins in Scotland, dating back to the 13th century. It is believed to be derived from the Scottish Gaelic words "carr" meaning "fort" or "rocky hill" and "uth" meaning "territory" or "land." This suggests that the name likely originated from a place name describing a fortified territory or settlement on a rocky hill.
The earliest recorded instances of the name can be found in various medieval Scottish records and charters. One notable example is the mention of a "William de Carruth" in the Ragman Rolls of 1296, a historical record of Scottish landowners who swore allegiance to King Edward I of England.
In the 15th century, the Carrouths were documented as a prominent family in the Scottish Borders region, particularly in the areas of Peeblesshire and Roxburghshire. The name appeared in various local records, such as the Exchequer Rolls of Scotland, where a "Robert Carruth" is mentioned in 1456.
The surname has also been spelled in various ways throughout history, including Carruth, Carrouthe, and Carruthers. These variations often reflected regional pronunciation and spelling preferences.
One notable bearer of the Carrouth name was Sir James Carrouth (1550-1623), a Scottish landowner and politician who served as a member of the Parliament of Scotland during the reign of King James VI.
Another figure of historical significance was Robert Carrouth (1660-1735), a Scottish minister and theologian who played a significant role in the Presbyterian Church of Scotland during the 18th century.
In the literary world, Agnes Carrouth (1820-1892) was a Scottish author and poet, known for her works celebrating Scottish culture and traditions.
The Carrouth name has also been associated with places in Scotland, such as Carrouth Hill in Lanarkshire and Carrouth Farm in Peeblesshire, further emphasizing its connection to the Scottish landscape and geography.
Throughout history, the Carrouth surname has maintained a strong presence in Scotland, particularly in the Borders region, where many descendants of the original Carrouth families continue to reside.

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 Carrouth surname at the time of the 2020 Census, not any inherent property of the name itself.
