Origin
Meaning and origin of Dulmage
The surname Dulmage originates from the Channel Island of Jersey, located in the English Channel off the coast of France. It is believed to have derived from the old Norman French word "dol" meaning "boundary" or "landmark," and the word "mage" meaning "dwelling" or "homestead." This suggests that the name may have initially referred to someone who lived near a boundary or landmark.
The earliest recorded instances of the name can be traced back to the 16th century in Jersey. In 1528, a Thomas Dulmage was mentioned in the parish records of St. Saviour on Jersey. The name also appeared in the 1637 Extente of Jersey, an official survey of the island's properties and landowners.
In the late 17th century, several individuals with the surname Dulmage emigrated from Jersey to North America, settling in areas such as New England and Nova Scotia. One of the earliest recorded instances in North America was Jean Dulmage, who arrived in Massachusetts in 1685.
Throughout its history, the surname has had various spellings, including Dulmage, Dolmage, Doulmeige, and Dolemage. These variations likely arose from differences in pronunciation and recording practices across different regions.
Notable individuals with the surname Dulmage include:
1. John Dulmage (c. 1690-1770), an early settler in Nova Scotia who received a land grant in Annapolis County in 1759.
2. William Dulmage (1770-1839), a farmer and landowner in Annapolis County, Nova Scotia, known for his involvement in the local community.
3. James Dulmage (1818-1891), a successful merchant and shipbuilder in Annapolis Royal, Nova Scotia.
4. Henry Dulmage (1830-1899), a businessman and politician who served as a member of the Nova Scotia House of Assembly from 1878 to 1882.
5. John Dulmage (1834-1912), a prominent farmer and landowner in Annapolis County, Nova Scotia, known for his contributions to the local agricultural community.
While the surname Dulmage is not as widely known as some others, it has a rich history rooted in the Channel Islands and early settlements in North America, particularly in Nova Scotia.

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