Origin
The surname Caselton is of English origin, tracing back to the medieval period in the county of Lincolnshire. It is believed to be a locational surname, derived from the place name Caselton or Casselton, which means "the farm or settlement belonging to a person named Cazel or Caswel."
The earliest recorded instance of the name Caselton can be found in the Feet of Fines for Lincolnshire from 1292, where a Walter de Caselton is mentioned. This suggests that the surname was already established by the late 13th century.
In the 14th century, the Pipe Rolls for Lincolnshire from 1332 mention a John de Caselton, and the Subsidy Rolls for the same county from 1381 list a Thomas Caselton. These records provide evidence of the surname's continued use and presence in the region during the Middle Ages.
The variant spelling Casselton is also encountered in historical documents, such as the Court Rolls of the Manor of Ingoldmells in Lincolnshire from 1458, where a Richard Casselton is named. This spelling variation highlights the flexibility and evolution of surnames in their early stages.
One notable individual bearing the surname Caselton was William Caselton (c. 1520 - 1593), an English clergyman and academic who served as the Regius Professor of Divinity at the University of Oxford in the 16th century.
Another figure of historical significance was Sir Robert Caselton (1570 - 1637), a wealthy merchant and member of the Worshipful Company of Mercers in London. He was known for his philanthropic efforts, contributing to the establishment of educational institutions and charitable organizations.
In the 17th century, Thomas Caselton (1612 - 1689) was a prominent English lawyer and judge who served as a Justice of the Court of Common Pleas under the reign of Charles II.
The surname Caselton also has connections to the literary world through the writer and poet Elizabeth Caselton (1793 - 1867), whose works explored themes of nature and spirituality.
Lastly, Sir Henry Caselton (1840 - 1912) was a distinguished British diplomat and civil servant who served as the Governor of the Straits Settlements (modern-day Singapore, Malaysia, and Penang) in the late 19th century.
Demographics
Among Census respondents with the surname Caselton, the largest self-reported group is White at 94.4%. The next largest groups are Black (2.8%) and Hispanic (0.9%).
The bar chart below shows how Caselton 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 Caselton surname at the time of the 2020 Census, not any inherent property of the name itself.
