Origin
Meaning and origin of Strup
The surname STRUP originated in Scandinavia, particularly in Denmark and Norway, in the medieval period around the 12th century. It is believed to be derived from the Old Norse word "strup," which means "throat" or "neck." This suggests that the name may have originally been a descriptive nickname referring to a physical characteristic or occupation related to the neck or throat area.
One of the earliest recorded instances of the name STRUP can be found in the Danish census records of the 16th century, where it was spelled as "Strup." The name also appears in Norwegian church records from the same period, with variations such as "Strupe" and "Stropp."
In the 17th century, the name STRUP gained prominence in Denmark with the birth of Niels Strup (1633-1677), a Danish merchant and shipowner. He played a significant role in the Danish East India Company and was known for his successful trading ventures in the Indian Ocean region.
Another notable figure was Johan Strup (1786-1853), a Norwegian military officer and politician. He served in the Norwegian Constituent Assembly and played a crucial role in the drafting of the Norwegian Constitution in 1814.
In the 19th century, the name STRUP became associated with the Danish aristocracy. Herman Strup (1837-1905) was a Danish nobleman and landowner who held the title of Count of Gammel Estrup. He served as the Minister of Justice and later as the Prime Minister of Denmark from 1900 to 1905.
The name STRUP also has a connection to the field of education. Carl Strup (1805-1875) was a Danish educator and linguist who made significant contributions to the study of Scandinavian languages. He served as the headmaster of the prestigious Herlufsholm School in Denmark.
In Norway, the name STRUP is linked to the literary world. Kristian Strup (1858-1937) was a Norwegian writer and poet known for his contributions to the Nynorsk language movement. He published several collections of poetry and worked as a teacher and editor.
These are just a few examples of the many individuals who have carried the surname STRUP throughout history, highlighting its Scandinavian origins and its presence across various fields and professions.

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

Does the Census include every surname?
