Origin
Meaning and origin of Clariday
The surname Clariday is believed to have originated in the English counties of Yorkshire and Lincolnshire during the early medieval period, around the 12th or 13th century. It is thought to be derived from the Old English words "clær" and "dæg," which together translate to "bright day" or "clear day." This suggests that the name may have initially been a descriptive surname given to someone who was born or lived in a place with particularly bright and clear days.
One of the earliest recorded instances of the name can be found in the Pipe Rolls of Yorkshire from 1166, which mention a person named Robert Claridai. The surname also appears in the Hundred Rolls of Lincolnshire from 1273, where it is spelled "Clareday." These early records indicate that the name was present in the northern regions of England during the 12th and 13th centuries.
In the 14th century, the surname is documented in various records, including the Poll Tax Returns of Yorkshire from 1379, which list a John Clariday. Around the same time, the name is also found in the Court Rolls of the Manor of Wakefield, where it is spelled "Clariday" and "Clarydaye."
During the late medieval and early modern periods, the surname continued to be concentrated in the northern counties of England, particularly in Yorkshire and Lincolnshire. Notable individuals with the surname include John Clariday (c. 1520-1590), a landowner and farmer from the village of Cawthorne in Yorkshire, and William Clariday (c. 1580-1642), a merchant from the city of Lincoln.
In the 17th century, the name appears in various parish records and registers across Yorkshire and Lincolnshire. For example, the baptism of Mary Clariday is recorded in the parish of Darfield, Yorkshire, in 1632, and the marriage of Robert Clariday and Elizabeth Holt is documented in the parish of Gainsborough, Lincolnshire, in 1671.
Another notable figure with the surname was Thomas Clariday (1688-1756), a farmer and landowner from the village of Epworth in Lincolnshire. Additionally, the burial of John Clariday is recorded in the parish of Harworth, Nottinghamshire, in 1743.
While the surname Clariday has its roots in the northern counties of England, it eventually spread to other parts of the country and beyond, with bearers of the name continuing to contribute to various aspects of society throughout history.

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.

Keep in mind that these are self-reported numbers.
