Origin
The surname Rothley has its origins in England, dating back to the medieval period. It is believed to be a locational name, derived from the place name Rothley, a village in Leicestershire. The name itself is thought to come from the Old English words "rod" meaning "a cleared area" and "leah" meaning "a woodland clearing or meadow."
The earliest recorded mention of the name Rothley can be found in the Domesday Book of 1086, where it appears as "Rodolai" or "Rodeleia." This suggests that the name was already well-established in the region by the time of the Norman Conquest in 1066.
In the 13th century, records show that a certain William de Rothley held lands in Leicestershire, indicating that the surname had become hereditary by that time. Another notable bearer of the name was John Rothley, a wealthy merchant and landowner who lived in the 14th century.
During the 16th and 17th centuries, the Rothley family gained prominence in the county of Leicestershire. One notable member was William Rothley (c. 1545-1620), who served as the High Sheriff of Leicestershire in 1596.
In the 18th century, the surname spread to other parts of England, with records showing Rothleys residing in places like Lincolnshire and Yorkshire. A prominent figure from this period was Thomas Rothley (1725-1799), a successful businessman and philanthropist from Nottinghamshire.
As the Rothley surname migrated across England, it evolved into various spelling variations, such as Rothly, Rotheley, and Rotheley. One notable bearer of this variant was Sir John Rotheley (c. 1460-1536), a member of the English gentry and a supporter of the Tudor dynasty.
Other notable individuals with the surname Rothley include:
1. Robert Rothley (c. 1580-1644), an English clergyman and author.
2. Edward Rothley (1692-1758), a wealthy landowner and Member of Parliament for Leicestershire.
3. Anne Rothley (1720-1788), a prominent philanthropist and benefactor to several charitable institutions in Leicestershire.
4. William Rothley (1794-1876), a renowned architect who designed several notable buildings in London and the surrounding areas.
5. Mary Rothley (1832-1912), a pioneering educator and advocate for women's education in the late 19th century.
Demographics
Among Census respondents with the surname Rothley, the largest self-reported group is White at 97.3%. The next largest groups are Hispanic (1.8%) and Black (0.9%).
The bar chart below shows how Rothley 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 Rothley 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.
