Origin
The surname Kaighin is believed to have originated in England, specifically in the county of Lancashire. It dates back to the 12th century and is thought to be derived from the Old English words "caeg" and "hinna," which together mean "the young male deer or fawn."
One of the earliest recorded instances of the name appears in the Pipe Rolls of Lancashire from 1177, where it is spelled "Cagehyn." This suggests that the name may have initially been used as a nickname or descriptive term for someone who was agile or swift like a young deer.
During the 13th century, the name began to be used as a surname, and various spellings emerged, such as "Cagheyn," "Cagehin," and "Kaighin." These variations likely resulted from regional dialects and the evolving nature of language over time.
In the 14th century, the name Kaighin is found in the Lancashire Inquests and Extents from 1310, indicating that individuals with this surname were landowners or held positions of authority in the region.
One notable person with the surname Kaighin was John Kaighin, born in 1625 in Lancashire. He was a prominent Quaker and a member of the Religious Society of Friends, actively participating in the religious and social movements of his time.
Another individual of historical significance was William Kaighin, born in 1678 in Preston, Lancashire. He was a successful merchant and philanthropist, known for his contributions to the local community and support of education initiatives.
In the 18th century, the Kaighin family established roots in various parts of England, with records showing individuals bearing the name in counties such as Yorkshire and Derbyshire.
A notable figure from this period was Thomas Kaighin, born in 1742 in Yorkshire. He was a respected scholar and writer, publishing several works on literature and philosophy that gained recognition among his contemporaries.
Moving into the 19th century, the Kaighin surname continued to be associated with notable individuals, such as Robert Kaighin, born in 1815 in Lancashire. He was a successful industrialist and philanthropist, contributing to the economic and social development of the region.
Throughout its history, the surname Kaighin has maintained a strong connection to its English roots, with many families tracing their lineage back to the counties of Lancashire and Yorkshire.
Demographics
Among Census respondents with the surname Kaighin, the largest self-reported group is White at 93.4%. The next largest groups are Two or More Races (5.8%) and Black (0.8%).
The bar chart below shows how Kaighin 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 Kaighin 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.
