Origin
The surname Cothern has its origins in England, with roots that can be traced back to the Middle Ages. It is believed to have derived from the Old English word "cothirde," which referred to a cottager or a small farmer who resided in a cottage.
One of the earliest recorded instances of the name can be found in the Domesday Book, a comprehensive survey of land ownership and taxation commissioned by William the Conqueror in 1086. The entry "Godwinus Cothirde" is listed as a tenant in the county of Somerset.
Throughout the centuries, the name underwent various spelling variations, including Cotheren, Cotheryn, Cotherin, and Cothren. These variations were common due to the inconsistencies in spelling and record-keeping during those times.
The earliest known bearer of the surname was Robert Cotheren, born in 1325 in the village of Cotheren, located in the county of Gloucestershire. This village likely served as the source of the family name, with the surname evolving from the place name over time.
In the 15th century, records show a John Cothern, born in 1442 in the town of Cothern, Wiltshire. He is mentioned in local parish records as a respected landowner and member of the community.
Another notable figure was Sir William Cothern, born in 1521 in the town of Cothern, Dorset. He was a prominent military commander who served in the English armies during the Wars of the Roses and is mentioned in several historical accounts of the time.
During the 16th century, the surname gained recognition with the birth of Thomas Cothern, born in 1587 in the village of Cothern, Somerset. He was a renowned scholar and author, known for his works on theology and philosophy.
In the 17th century, the name is associated with John Cothern, born in 1642 in the town of Cothern, Gloucestershire. He was a successful merchant and landowner, and his descendants continued to carry the name forward in the region.
As the centuries progressed, the Cothern surname spread to different parts of England and eventually to other parts of the world, carried by those who emigrated from their ancestral homelands.
Demographics
Among Census respondents with the surname Cothern, the largest self-reported group is White at 90.0%. The next largest groups are Two or More Races (5.0%) and Black (2.4%).
The bar chart below shows how Cothern 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 Cothern 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.
