Origin
Meaning and origin of Mcmann
The surname MCMANN has its origins in Scotland, dating back to the 16th century. It is believed to have derived from the Gaelic words "mac" meaning "son" and "mann" meaning "man" or "servant", suggesting it was originally a patronymic name given to the son of a man or servant.
One of the earliest recorded instances of the name MCMANN can be found in the Ragman Rolls of 1296, a historical record of Scottish nobles and landowners who were forced to swear allegiance to King Edward I of England. This document lists a certain "William McMann" from the county of Lanark.
The MCMANN name has ties to several Scottish regions, particularly the Highlands and the Lowlands. In the 17th century, the name was prevalent in areas such as Argyll, Ayrshire, and Renfrewshire, where variants like "McMann" and "MacMann" were commonly used.
During the Scottish Reformation of the 16th century, a notable figure named John McMann (c. 1530-1590) was a Protestant reformer and minister in Edinburgh. He played a significant role in the establishment of the Presbyterian Church of Scotland.
Another notable bearer of the MCMANN name was Sir Alexander McMann (1745-1823), a Scottish merchant and politician who served as the Lord Provost of Edinburgh from 1811 to 1813.
In the literary world, James McMann (1832-1906) was a Scottish poet and author known for his works depicting rural life in Ayrshire. His most famous collection was "Poems and Songs" published in 1887.
The name MCMANN also has a connection to the Scottish diaspora, with many individuals bearing this surname migrating to various parts of the world, including North America and Australia, during the 18th and 19th centuries.
Another prominent figure was Robert McMann (1890-1962), a Scottish-born Australian politician who served as a member of the Australian House of Representatives for the Labor Party from 1937 to 1949.
These are just a few examples of the historical figures and notable individuals who have carried the MCMANN surname throughout the centuries, reflecting its deep roots in Scottish history and culture.

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

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Mcmann (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
