Origin
Meaning and origin of Macculloch
The surname MACCULLOCH is of Scottish origin, traced back to the 12th century. It is a territorial name derived from the lands of Culloch, located in the old Barony of Lochow in Argyllshire. The prefix "Mac" means "son of" in Gaelic, indicating that the name was originally associated with the son of someone from the Culloch area.
The name is believed to have originated from the Gaelic word "cullach," which means "boar" or "male pig." This suggests that the earliest bearers of the name may have lived in an area known for its boar population or were perhaps involved in hunting or trading these animals.
Historical records show variations in the spelling of the name, including MacCulloch, McCulloch, and McCullough. One of the earliest documented references to the name is in the Ragman Rolls of 1296, which lists Dugal MacCulloch as a landowner who swore fealty to King Edward I of England.
In the 14th century, the MACCULLOCH clan played a significant role in the Wars of Scottish Independence, supporting Robert the Bruce. Godfrey MACCULLOCH, born around 1300, was a prominent figure in this conflict and is mentioned in various historical accounts of the time.
The MACCULLOCH family continued to hold lands in Argyllshire and other parts of Scotland throughout the centuries. Notable individuals bearing this surname include:
1. Sir Evan MACCULLOCH (1537-1619), a Scottish soldier and landowner who served as Captain of the King's Guard.
2. Horatio MACCULLOCH (1805-1867), a renowned Scottish landscape painter known for his depictions of the Scottish Highlands.
3. John Ramsay MACCULLOCH (1789-1864), a Scottish geologist and chemist who made significant contributions to the study of igneous rocks.
4. John MACCULLOCH (1773-1835), a Scottish-born writer and travel author known for his works on the Western Isles of Scotland.
5. Bianca MACCULLOCH (born 1972), a Canadian actress and screenwriter best known for her work on the television series "The Listener."
The name MACCULLOCH has a rich history rooted in Scotland's past, with its origins dating back to the 12th century and its bearers playing important roles in various aspects of Scottish society, from warfare and land ownership to arts, sciences, and literature.

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