Origin
Meaning and origin of Dinzey
The surname DINZEY is believed to have originated in England during the Middle Ages. It is thought to be a locational name, derived from a place name such as Dinsdale or Dinsley. These place names are thought to have derived from the Old English words "dene," meaning valley, and "ley," meaning a clearing or meadow.
One of the earliest recorded instances of the name DINZEY can be found in the Assize Rolls of Yorkshire from the year 1219, where it appears as "Dinzey." This suggests that the name was already well-established in northern England by the early 13th century.
In the 14th century, the DINZEY name appears in the Subsidy Rolls of Westmorland, where a Robert Dynzey is listed. This record provides evidence of the name's spread across northern England during this period.
During the 16th century, the DINZEY name can be found in various records from the county of Lancashire. One notable individual from this time was John Dinzey, a merchant who lived in Preston in the late 1500s.
In the 17th century, the DINZEY name appears to have spread to other parts of England. Records from this period show individuals with the surname living in counties such as Gloucestershire and Somerset.
One of the most prominent figures with the DINZEY surname was Sir John Dinzey (1620-1692), a Member of Parliament for the borough of Bridgwater in Somerset. He was also a successful merchant and landowner.
Another notable DINZEY was William Dinzey (1675-1742), a wealthy merchant and shipowner from Bristol. He was involved in the transatlantic trade and played a significant role in the city's maritime industry.
In the 18th century, the DINZEY name continued to be found in various parts of England. One individual of note was Thomas Dinzey (1720-1789), a prominent landowner and magistrate from Gloucestershire.
As the centuries progressed, the DINZEY surname spread to other parts of the world, particularly through emigration to North America and other British colonies. However, its origins can be traced back to the valleys and meadows of medieval England, where the name first took root.

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