Origin
The surname Whitmore is of English origin, derived from a place name referring to a white or light-colored area. It likely emerged in the medieval period, around the 12th or 13th century.
The name is believed to have originated in Staffordshire, where there are several locations with similar names, such as Whitmore Reans and Whitmore Village. It may also be connected to the Whitmore Estate in Shropshire.
One of the earliest recorded instances of the name is found in the Domesday Book of 1086, where it appears as "Witemore." This suggests the name was already established in England by the late 11th century.
In the 13th century, a Walter de Witemore was documented as holding lands in Staffordshire. This provides evidence of the surname's use during the Middle Ages.
One notable bearer of the name was Sir George Whitmore (c. 1636-1723), an English politician and Member of Parliament for Bridgnorth from 1685 to 1687.
Another prominent figure was William Wolryche Whitmore (1787-1858), an English antiquarian and historian who wrote extensively on the history of Shropshire and Staffordshire.
Reverend Charles Edward Whitmore (1822-1892) was an English clergyman and author, known for his works on the history of the Whitmore family.
In the United States, John Whitmore (1778-1835) was a lawyer and politician who served as a Congressman from Massachusetts from 1811 to 1813.
William Henry Whitmore (1836-1900) was an American genealogist and historian, known for his publications on the early settlers of New England.
The Whitmore surname has a long and well-documented history, with roots dating back to medieval England and connections to various regions, particularly Staffordshire and Shropshire. It has been borne by notable individuals across different fields over the centuries.
Demographics
Among Census respondents with the surname Whitmore, the largest self-reported group is White at 72.0%. The next largest groups are Black (18.8%) and Two or More Races (4.6%).
The bar chart below shows how Whitmore 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 Whitmore 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.
