Origin
The surname Lumb is of English origin and dates back to the medieval period. It is derived from the Old English word "lumb," meaning a small valley or a deep, wooded ravine. The name is therefore a topographical surname, referring to someone who lived near or in such a location.
The earliest recorded instances of the name can be found in various historical records, including the Domesday Book of 1086. In this famous survey commissioned by William the Conqueror, there are references to places with names like "Lumb" and "Lombe," which likely contributed to the development of the surname.
One of the earliest known bearers of the name was John de Lumb, who lived in Yorkshire, England, in the 13th century. Other early instances include Robert de Lumb, mentioned in the Subsidy Rolls of Lancashire in 1332, and William de Lumb, who was recorded in the Poll Tax Returns of Yorkshire in 1379.
The name Lumb is also associated with various place names in England, such as Lumb Foot in Lancashire, Lumb Bank in West Yorkshire, and Lumbs Lane in Cheshire. These locations may have derived their names from the Old English word "lumb," and some of them could have been the original homes of families who adopted the surname.
Throughout history, there have been several notable individuals with the surname Lumb. One example is John Lumb (1665-1698), an English mathematician and astronomer who made significant contributions to the study of comets and published works on celestial mechanics. Another is Richard Lumb (1738-1808), an English poet and playwright who wrote numerous works, including the play "The Airs of Arminius."
Other notable bearers of the name include William Lumb (1805-1870), a British businessman and philanthropist who made his fortune in the textile industry and donated generously to educational causes; Mary Lumb (1870-1944), an English writer and poet known for her children's stories and nature poetry; and James Lumb (1886-1964), a British trade unionist and politician who served as a Labour Party Member of Parliament for several years.
While the surname Lumb is relatively uncommon, it has endured through the centuries, carrying with it the rich history and linguistic roots of the English language and the topographical features of the country's landscapes.
Demographics
Among Census respondents with the surname Lumb, the largest self-reported group is White at 88.0%. The next largest groups are Black (4.3%) and Hispanic (3.8%).
The bar chart below shows how Lumb 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 Lumb surname at the time of the 2020 Census, not any inherent property of the name itself.
