Origin
Meaning and origin of Hoorn
The surname Hoorn is of Dutch origin and dates back to the medieval period. It is derived from the place name Hoorn, a city in the province of North Holland, Netherlands. The name itself is derived from the Dutch word "hoorn," meaning "horn," referring to the town's location on a horn-shaped peninsula.
The earliest recorded instances of the surname Hoorn can be found in Dutch records from the 13th century, such as the "Oorkondenboek van Holland en Zeeland" (Charter Book of Holland and Zeeland). One of the earliest known bearers of the name was Willem van Hoorn, a Dutch nobleman who lived in the late 13th century.
The surname Hoorn is also associated with several notable historical figures. One such figure was Philips van Hoorn, a Dutch naval officer and explorer who commanded several expeditions to the East Indies in the early 17th century. Another notable bearer of the name was Cornelis van Hoorn, a Dutch military officer who served in the Dutch East Indies during the 17th century.
In the 16th century, the Hoorn family played a significant role in the Dutch Revolt against Spanish rule. Johan van Hoorn, a Dutch noble and military commander, was a key figure in the early stages of the revolt, leading forces against the Spanish in the Battle of Heiligerlee in 1568.
The surname Hoorn has also been linked to various place names and older spellings. For instance, the town of Hoorn was formerly known as "Hoornen" or "Hornen," which may have influenced earlier spellings of the surname.
Other notable individuals with the surname Hoorn include:
1. Pieter van Hoorn (1553-1609), a Dutch naval officer and explorer.
2. Gerard van Hoorn (1605-1666), a Dutch Golden Age painter.
3. Hendrik van Hoorn (1718-1793), a Dutch architect and city planner.
4. Willem van Hoorn (1820-1897), a Dutch politician and statesman.
5. Lodewijk van Hoorn (1857-1925), a Dutch landscape painter.
While the surname Hoorn originated in the Netherlands, it has since spread to other parts of the world, particularly through Dutch emigration and colonization efforts. However, its roots and historical significance remain deeply tied to the Dutch culture and the city of Hoorn.

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