Origin
The surname Muchison originates from the Scottish Lowlands and is believed to have emerged in the 13th century. It is derived from the Old English word "much," meaning "great" or "large," and the suffix "-son," indicating a patronymic name.
In its earliest form, the name was likely spelled as "Muckeson" or "Mukkeson," reflecting the Scottish pronunciation. One of the earliest recorded instances of the name can be found in the Exchequer Rolls of Scotland from 1264, where a person named "Willielmus Mukkesone" is mentioned.
The name is thought to have been initially adopted by individuals who were considered physically large or imposing, or perhaps those who held a position of importance within their community. Over time, as the name passed from generation to generation, various spelling variations emerged, including Muchison, Muckison, and Muchieson.
In the 16th century, the name appears in the records of the Parish of Holyrood in Edinburgh, where a John Muckison was recorded as a resident in 1567. Another notable individual bearing this surname was Robert Muchison, a Scottish geologist and pioneer in the study of Paleozoic era rocks, born in 1792 and died in 1871.
One of the earliest known bearers of the Muchison surname was Sir Thomas Muchison, a Scottish knight who fought alongside Robert the Bruce during the Wars of Scottish Independence in the early 14th century. He was awarded lands in Renfrewshire for his bravery and loyalty.
In the late 17th century, a family with the surname Muchison settled in the village of Kilwinning, Ayrshire. One of their descendants, James Muchison, born in 1718, became a prominent merchant and landowner in the region.
Another notable individual was Margaret Muchison, born in 1825 in Aberdeenshire, who was a pioneering educator and advocate for women's rights. She founded one of the first schools for girls in Scotland and played a significant role in the advancement of education for women during the Victorian era.
These are just a few examples of individuals who have borne the surname Muchison throughout history, highlighting its Scottish origins and the various areas where it has been found over the centuries.
Demographics
Among Census respondents with the surname Muchison, the largest self-reported group is Black at 83.2%. The next largest groups are White (9.3%) and Two or More Races (3.7%).
The bar chart below shows how Muchison 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 Muchison 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.
