Origin
The surname Wallis originated in England and is derived from the Old English term "Wallisc" meaning "foreign" or "Celtic". It was initially used as a descriptive surname for people of Celtic or Welsh descent living in England.
The earliest recorded instance of the name dates back to the Domesday Book of 1086, where it appears as "Wallensis". This Latin form was used to refer to individuals of Welsh origin residing in various parts of England. The name was particularly prevalent in areas bordering Wales, such as Shropshire, Herefordshire, and Gloucestershire.
In the 13th century, the name was often spelled as "Waleys" or "Waleys", reflecting the Middle English pronunciation. During this period, the name appeared in various records, including the Hundred Rolls of 1273, where it was listed as "Waleys" in Oxfordshire.
One of the earliest known bearers of the name was William Wallis, a prominent English mathematician and clergyman born around 1616. He made significant contributions to the field of mathematics and is remembered for his work on cycloids and conic sections.
Another notable individual with the surname Wallis was Samuel Wallis, an English navigator and explorer born in 1728. In 1767, he led an expedition to the Pacific Ocean, during which he discovered several islands, including Tahiti.
John Wallis, born in 1668, was an English grammarian and philologist who is best known for his work titled "Grammatica Linguae Anglicanae". His scholarly contributions to the study of the English language were highly influential in his time.
In the 18th century, the name Wallis was also associated with places, as evidenced by the town of Wallisdown in Dorset, England. This place name is believed to have derived from the surname, reflecting the presence of Wallis families in the area.
Another notable bearer of the surname was Barnes Wallis, an English scientist and engineer born in 1887. He is renowned for his work during World War II, particularly for inventing the "bouncing bomb" used in the famous Dambusters raid on German dams.
Throughout its history, the surname Wallis has been associated with individuals from diverse fields, including mathematics, exploration, linguistics, and engineering, reflecting the rich heritage and contributions of those bearing this name.
Demographics
Among Census respondents with the surname Wallis, the largest self-reported group is White at 86.7%. The next largest groups are Hispanic (4.3%) and Two or More Races (4.2%).
The bar chart below shows how Wallis 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 Wallis 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.
