Origin
The surname COOMER is believed to have originated in England, with the earliest records dating back to the late 12th century. It is thought to be derived from the Old English word "cuman," meaning "to come" or "to arrive." This suggests that the name may have initially referred to someone who had recently arrived in a particular area or settlement.
One of the earliest recorded instances of the name can be found in the Curia Regis Rolls of 1201, where a certain Robert Cumer is mentioned. Another early reference appears in the Pipe Rolls of Oxfordshire from 1230, which lists a William Comere.
The name COOMER is closely related to the more common surname "Comer," which shares a similar origin. Some historical records show variations in spelling, such as Comere, Commer, and Cumer, reflecting the fluid nature of surnames in early English history.
During the 13th and 14th centuries, the name appears to have been concentrated in the counties of Oxfordshire, Gloucestershire, and Somerset. This may indicate that the family had roots in these regions or that the name originated from place names in these areas.
One notable historical figure bearing the surname COOMER was John Coomer (c. 1633-1689), an English politician who served as a Member of Parliament for Salisbury in the late 17th century. Another prominent individual was Thomas Coomer (1747-1828), a renowned English architect and surveyor who designed several notable buildings in Bath and Bristol.
In the 16th century, there is a record of a Richard Coomer (c. 1520-1589) who was a merchant and alderman in the city of Bristol. He played a significant role in the city's trade and governance during the reign of Queen Elizabeth I.
The name COOMER also appears in some early American records, indicating that individuals with this surname were among the early settlers in the British colonies. One example is James Coomer (1734-1818), a soldier from Virginia who fought in the American Revolutionary War.
Another notable figure was William Coomer (1785-1853), an English architect and civil engineer who was responsible for designing several bridges and other structures in the early 19th century, including the Royal Suspension Bridge in Bath.
While the surname COOMER is not among the most common in England or the United States, it has a rich history spanning several centuries and has been associated with individuals from various walks of life, including politicians, architects, merchants, and soldiers.
Demographics
Among Census respondents with the surname Coomer, the largest self-reported group is White at 91.1%. The next largest groups are Two or More Races (4.0%) and Hispanic (2.9%).
The bar chart below shows how Coomer 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 Coomer 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.
