Origin
The surname Kortendick has its origins in the Low German language of northern Germany and the Netherlands. It is believed to have originated in the late medieval period, around the 14th or 15th century. The name is likely derived from the Dutch words "kort" meaning short and "dijk" meaning dike or embankment, suggesting it may have originally referred to someone living near a short dike or embankment.
Some of the earliest recorded instances of the name can be found in church records and municipal archives from the region of Lower Saxony in northern Germany. One of the earliest known bearers of the name was Hans Kortendick, a farmer from the village of Emden, who was born around 1550.
In the 17th century, the name appears in the records of the Dutch East India Company, with a merchant named Pieter Kortendick mentioned as having traded in the port of Batavia (modern-day Jakarta) in 1642. This suggests that some bearers of the name may have been involved in the Dutch colonial trade networks of that era.
Another notable figure in the history of the Kortendick surname was Johann Kortendick, a Lutheran pastor who lived in the city of Lübeck in northern Germany in the late 17th century. He is known to have authored several religious texts and sermons that were published in the 1680s.
In the 19th century, the name can be found in various records from the provinces of Friesland and Groningen in the Netherlands, where it was likely borne by farmers and tradesmen. One notable individual from this period was Willem Kortendick, a Dutch painter born in Groningen in 1822, who was known for his landscape and genre paintings.
Another significant bearer of the Kortendick name was Karl Kortendick, a German industrialist born in Hanover in 1856. He founded the Kortendick Machine Works, a successful engineering company that produced machinery for the textile industry, and played a role in the industrial development of the region.
While the surname Kortendick is relatively uncommon, it has a long and interesting history, with bearers of the name leaving their mark in various fields over the centuries, particularly in the regions of northern Germany and the Netherlands.
Demographics
Among Census respondents with the surname Kortendick, the largest self-reported group is White at 99.2%. The next largest groups are Hispanic (0.8%).
The bar chart below shows how Kortendick 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 Kortendick surname at the time of the 2020 Census, not any inherent property of the name itself.
