Origin
The surname Cottis has its origins in the British Isles, specifically England, and can be traced back to the Middle Ages. It is believed to be derived from the Old English word "cot," meaning a small dwelling or cottage. This suggests that the name may have originally referred to someone who lived in a modest home or a small settlement.
One of the earliest recorded instances of the name Cottis can be found in the Domesday Book, a comprehensive survey of landholdings in England commissioned by William the Conqueror in 1086. The Domesday Book mentions several individuals with variations of the name, such as Cottus and Cotis, indicating that the surname was already in use during the Norman period.
During the 13th century, there are records of a family named Cottis residing in the county of Somerset. The name also appeared in various medieval records and manuscripts, including the Pipe Rolls of the 12th and 13th centuries, which documented royal finances and land transactions.
In the 16th century, a notable individual bearing the surname Cottis was John Cottis, a landowner and prominent figure in the city of Bristol. He was born around 1520 and played an active role in local politics and civic affairs.
Another historical figure with the surname Cottis was Sir Thomas Cottis, who lived in the 17th century. He was a successful merchant and served as the Lord Mayor of London in 1672. Sir Thomas Cottis was also involved in various charitable endeavors and contributed to the rebuilding efforts after the Great Fire of London in 1666.
In the 18th century, a branch of the Cottis family settled in the county of Yorkshire, where they became influential landowners and businessmen. One notable member was William Cottis, born in 1740, who was a successful industrialist and owned several textile mills.
The surname Cottis has also been associated with various place names in England, such as Cottis Green in Oxfordshire and Cottis Hill in Gloucestershire. These place names may have derived from the presence of families bearing the surname in those areas.
Other prominent individuals with the surname Cottis include Robert Cottis, a respected scholar and author born in 1810, who wrote extensively on English literature and history. Additionally, Edward Cottis, born in 1865, was a renowned architect known for his innovative designs and contributions to the development of modern architecture in Britain.
Demographics
Among Census respondents with the surname Cottis, the largest self-reported group is White at 94.7%. The next largest groups are Two or More Races (1.8%) and Black (0.9%).
The bar chart below shows how Cottis 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 Cottis 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.
