The surname Maxwell has its origins in Scotland, first appearing in the early 12th century. It is derived from the Old English words "mæssere" meaning "monk" and "welle" meaning "stream", referring to a monastery or chapel near a stream or spring. The name likely originated in the area around the town of Maxwell in Roxburghshire, Scotland.
The earliest recorded reference to the surname is found in the Ragman Rolls of 1296, where Aymer de Maxwell is listed as a landowner who swore fealty to King Edward I of England. Another early record is from the Exchequer Rolls of Scotland in 1390, which mentions John de Maxwell of Caerlaverock.
The Maxwell family played a prominent role in Scottish history, with several members holding important positions and titles. One notable figure was Sir Herbert Maxwell, who was appointed Lord Maxwell in 1445 and later became the 1st Lord Maxwell. Another was Robert Maxwell, the 5th Lord Maxwell (c.1493-1546), who fought against the English at the Battle of Solway Moss in 1542.
In England, the name is also found in early records, such as the Pipe Rolls of Yorkshire from 1166, which mentions a Richard Maxwell. The Maxwells were also landowners in Northumberland and Cumberland, with the village of Maxwell in Cumbria likely named after them.

Demographics
Among Census respondents with the surname Maxwell, the largest self-reported group is White at 70.1%. The next largest groups are Black (20.2%) and Two or More Races (4.4%).
The bar chart below shows how Maxwell 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 Maxwell 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 Maxwell (2000, 2010, 2020).
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.
