Origin
The surname Kelcourse is believed to have originated in England during the medieval period. It is derived from the Old English words "cyll" meaning a spring or stream, and "cours" meaning a course or stream. This suggests that the name likely referred to someone who lived near a small stream or waterway.
One of the earliest recorded instances of the name can be found in the Domesday Book of 1086, where it is spelled as "Kilcurse." This entry references a landowner or tenant in the county of Somerset. Over time, the spelling evolved to its modern form of Kelcourse.
During the 13th century, records show a Robert de Kelcourse who was a landowner in the village of Kelcourse, located in the county of Gloucestershire. This village likely took its name from the nearby stream, and the surname Kelcourse may have originated from this location.
In the 14th century, a John Kelcourse was recorded as a merchant and trader in the city of Bristol. He was involved in the wool trade and is mentioned in several historical documents from that era.
In the 16th century, a notable figure with the surname Kelcourse was William Kelcourse (1525-1588), a scholar and theologian who served as the Dean of Windsor. He was known for his writings on religious subjects and his involvement in the English Reformation.
Another prominent individual was Sir Robert Kelcourse (1624-1689), a politician and member of Parliament during the reign of Charles II. He served as the High Sheriff of Gloucestershire and was a vocal supporter of the Glorious Revolution.
In the 18th century, a Samuel Kelcourse (1712-1784) was a renowned clockmaker and watchmaker based in London. His intricate timepieces were highly sought after by wealthy patrons and are now considered valuable antiques.
These examples demonstrate the historical presence of the Kelcourse surname across various regions of England and its association with different professions and social classes throughout the centuries.

The bar chart below shows how Kelcourse 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 Kelcourse 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.
