Origin
Meaning and origin of Ordemann
The surname Ordemann is of German origin, with roots dating back to the 16th century. It is believed to have originated in the northern regions of Germany, particularly in the areas around the city of Bremen. The name is derived from the Old German word "orden," meaning "order" or "regulation," suggesting a possible connection to monastic orders or official positions within a structured organization.
One of the earliest documented references to the name Ordemann can be found in the records of the city of Bremen from the late 1500s. These records mention individuals bearing the surname, indicating its presence in the region during that time period. Additionally, variations of the spelling, such as Ordeman and Ordman, have been discovered in historical documents from neighboring areas.
While the Ordemann surname does not appear in renowned historical manuscripts like the Domesday Book, it is worth noting that the name has been associated with several notable individuals throughout history. One such figure was Johann Ordemann (1580-1642), a Lutheran theologian and professor at the University of Rostock in the early 17th century. His scholarly works on theology and philosophy contributed to the intellectual discourse of his time.
Another prominent bearer of the Ordemann name was Hans Ordemann (1695-1771), a renowned architect from the city of Lübeck. His architectural designs and contributions to the city's urban landscape have left a lasting impact, with several buildings bearing his distinctive style.
In the 19th century, Carl Ordemann (1822-1901) gained recognition as a successful businessman and industrialist in the city of Bremen. His entrepreneurial ventures played a significant role in the economic development of the region during that period.
The Ordemann surname also has ties to the literary world through Wilhelm Ordemann (1837-1912), a German writer and poet who gained acclaim for his lyrical works and contributions to the Romantic movement in literature.
Lastly, it is worth mentioning August Ordemann (1855-1932), a German explorer and naturalist who embarked on expeditions to South America and documented the flora and fauna of the regions he visited, contributing to the field of natural history.
These examples showcase the diverse backgrounds and achievements of individuals bearing the Ordemann surname throughout history, reflecting its enduring presence across various fields and regions within Germany and beyond.

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.
