Origin
Meaning and origin of Korreck
The surname Korreck originates from Germany, first appearing in records during the 16th century. It is believed to have derived from the Old German word "kora," meaning a chapel or small church. This suggests the name may have been initially given to someone who lived near or worked at a local chapel.
One of the earliest recorded instances of the Korreck name can be found in the church records of the town of Halle, dated 1563. The entry mentions a Hans Korreck, who was a baker by trade. Another early mention is from the village of Lahnstein in 1587, where a Wilhelm Korreck is listed as a vineyard owner.
In the 17th century, the Korreck name began appearing in various parts of the German states. Johann Korreck (1610-1672) was a respected theologian and professor at the University of Wittenberg. His published works on Lutheran teachings were widely read during his lifetime.
The 18th century saw the Korreck name spread further across Europe. Franz Korreck (1725-1805) was a renowned painter from Vienna, known for his portraiture and religious works adorning many churches in Austria and Bavaria.
As the 19th century dawned, the Korreck family had established itself in various professions and regions. Notable figures include:
- Karl Korreck (1801-1885), a Prussian military officer who fought in the Napoleonic Wars.
- Wilhelmine Korreck (1833-1908), a German opera singer and soprano who performed across Europe.
- Otto Korreck (1862-1944), a pioneering industrialist who founded the Korreck Machine Works in Berlin.
Throughout its long history, the Korreck surname has undergone slight variations in spelling, such as Korrek, Korrecke, and Korrecken, reflecting regional dialects and linguistic changes over time. However, the name's origins can be traced back to the modest beginnings of a small German chapel, a testament to the enduring legacy of this unique surname.

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