Origin
Meaning and origin of Duquesne
The surname DUQUESNE is of French origin, originating from the region of Picardy in northern France. It is derived from the Old French word "duchesne," which means "oak tree." The name likely referred to someone who lived near a prominent oak tree or in an area with an abundance of oak trees.
The earliest recorded instance of the name dates back to the 12th century, appearing in the records of the Abbey of Saint-Quentin in Picardy. The name was also found in the Trésor des Chartes, a collection of medieval French charters and documents, in the 13th century.
One of the earliest notable individuals with the surname DUQUESNE was Abraham Duquesne, a French naval officer and explorer born in 1610. He played a significant role in the French colonization of the West Indies and the Caribbean, establishing settlements on the islands of Guadeloupe and Martinique.
Another prominent figure was Abraham Duquesne, Marquis du Bouchet (1639-1688), a French naval commander who served under Louis XIV. He was renowned for his victories against the Dutch and Spanish fleets and his contributions to the development of the French navy.
In the 18th century, Fort Duquesne, a French military fort located in present-day Pittsburgh, Pennsylvania, was named after Marquis Duquesne, the governor of New France. The fort played a crucial role in the French and Indian War and was later rebuilt by the British and renamed Fort Pitt.
Julien Duquesne (1610-1687) was a French painter and engraver known for his religious works and portraiture. He was a member of the Académie Royale de Peinture et de Sculpture and worked for notable patrons such as Cardinal Richelieu and Louis XIV.
Henri Duquesne (1879-1942) was a French aviator and pioneer of early aviation. He was one of the first pilots to fly across the Mediterranean Sea and set several long-distance flight records in the early 20th century.
Throughout history, variations of the name DUQUESNE have appeared, such as Dequesne, Dukesne, and Duquesnes, reflecting regional spelling differences and linguistic changes over time.

The bar chart below shows how Duquesne 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 Duquesne surname at the time of the 2020 Census, not any inherent property of the name itself.
