Origin
The surname Locker has its origins in medieval England, with records dating back to the 13th century. The name is believed to be derived from the Old English word "locc," meaning a lock or enclosure, referring to someone who lived near a lockable gate or enclosure.
One of the earliest recorded instances of the name is found in the Hundred Rolls of Cambridgeshire from 1273, which mentions a Robert le Lokker. This spelling variation highlights the evolution of the name over time, with the addition and removal of letters and suffixes.
During the Middle Ages, the Locker name was particularly prevalent in the counties of Norfolk, Suffolk, and Essex in eastern England. These areas had a significant agricultural presence, and the name may have originally referred to someone responsible for securing enclosures or gates on farms or manors.
The Domesday Book of 1086, a comprehensive survey of landholdings in England commissioned by William the Conqueror, does not contain any direct references to the Locker surname. However, it does mention several place names that may have influenced the development of the name, such as Lockeridge in Wiltshire and Lockington in East Riding of Yorkshire.
One notable historical figure with the Locker surname was Sir William Locker (1663-1751), a British naval officer and politician who served as a Member of Parliament for Midhurstand and Sevenoaks. Another prominent individual was John Locker (1693-1760), a British writer and philosopher who published works on education and natural philosophy.
In the 17th century, John Locker (1598-1685), an English goldsmith and banker, established the Locker family as a prominent mercantile and financial dynasty in London. His grandson, John Locker (1669-1720), continued the family's success in banking and was a director of the Bank of England.
Another notable figure was Edward Hawke Locker (1777-1849), a British naval officer and author who served in the Royal Navy during the Napoleonic Wars and later wrote several popular works of travel literature.
Throughout its history, the Locker surname has been associated with various professions, from agriculture and trade to military service and literature, reflecting the diverse backgrounds and experiences of those who bore this name.
Demographics
Among Census respondents with the surname Locker, the largest self-reported group is White at 86.5%. The next largest groups are Black (6.2%) and Two or More Races (3.2%).
The bar chart below shows how Locker 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 Locker 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.
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.
