Origin
The surname Gilmer is of English origin, deriving from the Old English given name Gilemar or Gylmyr, which was composed of the elements "gil" meaning "ravine" or "valley" and "mær" meaning "famous." This name was particularly prevalent in the northern counties of England during the Middle Ages.
The earliest known record of the Gilmer name dates back to the 12th century, with mentions found in the Pipe Rolls of Yorkshire and the Curia Regis Rolls of Lincolnshire. The name also appeared in the Hundredorum Rolls of 1273, which were records of landowners in various counties.
In the 14th century, there are references to individuals bearing the Gilmer surname in various historical documents. One notable example is John Gilmer, a merchant from York, who was granted a license to trade in 1387.
During the 16th and 17th centuries, the Gilmer name was associated with several notable figures. Sir John Gilmer (1516-1585) was a renowned English lawyer and judge who served as the Chief Baron of the Exchequer. Thomas Gilmer (1577-1638) was a prominent theologian and clergyman who served as the Archdeacon of Essex.
The surname Gilmer also has connections to place names in England. The village of Gilmerton, located in the county of Leicestershire, is believed to have derived its name from the Gilmer family who once held lands there.
In the 18th century, George Gilmer (1700-1782) was a distinguished English architect who designed several notable buildings, including the Radcliffe Camera in Oxford. Another notable figure from this period was Thomas Gilmer (1718-1788), a British naval officer who served during the American Revolutionary War.
Moving into the 19th century, John Gilmer (1805-1868) was an American lawyer and politician who served as the 33rd Governor of Virginia. He was also a prominent figure in the Confederate States of America during the Civil War.
These are just a few examples of individuals bearing the Gilmer surname who have left their mark on history. The name's origins can be traced back to the Old English language and its prevalence in northern England during the Middle Ages, with records spanning several centuries and connections to both notable figures and place names.
Demographics
Among Census respondents with the surname Gilmer, the largest self-reported group is White at 71.5%. The next largest groups are Black (20.5%) and Two or More Races (4.2%).
The bar chart below shows how Gilmer 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 Gilmer 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. 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.
