Origin
Meaning and origin of Lumzy
The surname Lumzy traces its origins back to the early 14th century in the northern regions of England, specifically around the county of Northumberland. It is believed to have derived from the Old English word "lumm," which referred to a deep pool or a body of still water.
Historical records suggest that the earliest known bearer of this name was John de Lumzy, who was mentioned in the Assize Rolls of Northumberland in 1326. The name's spelling has evolved over the centuries, with variations such as Lumzie, Lummzy, and Lummzey appearing in various medieval documents.
One notable historical reference to the Lumzy name can be found in the Bursars' Accounts of Durham Cathedral Priory, which date back to the late 15th century. These accounts record payments made to individuals with the surname Lumzy for various services rendered to the cathedral.
The earliest recorded birth of an individual with the surname Lumzy was that of William Lumzy, born in the village of Bamburgh, Northumberland, in 1487. Another notable figure was Robert Lumzy, born in 1543 in the town of Alnwick, who served as a magistrate and played a role in the administration of justice in the region.
During the 16th and 17th centuries, the Lumzy family had strong ties to the coastal areas of Northumberland, with many members involved in maritime trades and fishing. One such individual was John Lumzy (1598-1673), a renowned shipbuilder from the town of Blyth.
In the 18th century, the Lumzy name began to spread beyond Northumberland, with members of the family establishing themselves in other parts of England and even venturing to the American colonies. A prominent figure from this era was Samuel Lumzy (1712-1784), a successful merchant who settled in Boston, Massachusetts, and played a role in the American Revolution.
Throughout the 19th century, the Lumzy surname continued to be found across various regions of England, with notable individuals such as the writer and poet Elizabeth Lumzy (1842-1912) and the philanthropist and social reformer William Lumzy (1821-1898), who worked tirelessly to improve the living conditions of the working class in industrial cities.

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

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
