Origin
Meaning and origin of Shelley
The surname Shelley is believed to have originated in England during the medieval period. It is derived from the Old English words 'sciell' or 'scyll', meaning a shelter or shed, and 'leah', which refers to a woodland clearing or meadow. Thus, the surname likely referred to someone who lived in a dwelling or homestead located in a clearing or forest glade.
The earliest recorded spelling of the name is found in the Domesday Book of 1086, where it appears as 'Seluelei' and 'Scelleslei'. These entries refer to places in Worcestershire and Essex, respectively, indicating that the name was already established in different parts of the country by the late 11th century.
During the 13th century, the surname appears in various records with spellings such as 'Shelleye', 'Scelley', and 'Schelley'. One notable early bearer of the name was John de Shelley, who was recorded in the Hundred Rolls of Oxfordshire in 1273.
In the 14th century, the name continued to be well-represented in various regions of England. For instance, Robert de Shelley was mentioned in the Subsidy Rolls of Staffordshire in 1327, while John Shelley was recorded in the Subsidy Rolls of Sussex in 1332.
Throughout history, several notable individuals have borne the Shelley surname. Sir Philip Shelley (1563-1627) was an English nobleman who served as the High Sheriff of Sussex. Percy Bysshe Shelley (1792-1822) was a renowned English Romantic poet, acclaimed for works such as "Ozymandias" and "Ode to the West Wind".
Other notable Shelleys include Richard Shelley (1513-1587), a Member of Parliament during the reign of Queen Elizabeth I, and Mary Wollstonecraft Shelley (1797-1851), the author of the iconic Gothic novel "Frankenstein". Sir John Shelley (1920-2021) was a British politician and peer who served as a Member of Parliament for over three decades.
The surname Shelley has endured through the centuries and continues to be well-represented in various parts of the English-speaking world, with its roots firmly grounded in the medieval English landscape and language.

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 Shelley surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Shelley (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
