Origin
Meaning and origin of Weirup
The surname WEIRUP is believed to have originated in Sweden during the 16th century. It is a locational name derived from the Swedish word "weir" meaning a dam or barrier across a river, and "up" meaning a small settlement or hamlet. This suggests that the name may have originated from a small village located near a dam or weir on a river.
The earliest recorded instances of the WEIRUP surname can be found in church records and tax rolls from the Swedish provinces of Västergötland and Östergötland in the late 1500s. One of the earliest documented individuals was Olof Weirup, a farmer from the village of Weirup in Västergötland, who was mentioned in a parish register in 1587.
In the 17th century, the WEIRUP name appears in several historical documents, including military records. Hans Weirup, born in 1612, was a soldier in the Swedish army during the Thirty Years' War, serving under King Gustavus Adolphus. Another notable individual was Karin Weirup, born in 1635, who was a landowner and prominent figure in the town of Linköping.
As the WEIRUP family spread across Sweden, variations in spelling emerged, such as Weyrup, Wajrup, and Vejrup. Some members of the family adopted additional bynames or patronymics, leading to surnames like Weirupsson or Weirupdotter.
In the 18th century, the WEIRUP name gained prominence in academic circles. Johan Weirup (1706-1782) was a renowned theologian and professor at Uppsala University, while his brother Carl Weirup (1712-1789) was a respected jurist and legal scholar.
Another notable figure in Swedish history was Nils Weirup (1820-1896), a politician and member of the Riksdag, Sweden's parliament. He played a significant role in the constitutional reforms of the late 19th century.
Throughout the centuries, the WEIRUP surname has been carried by individuals from various walks of life, including farmers, soldiers, academics, and politicians. While not a particularly common name, it has left a lasting mark on Swedish history and culture.

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