Origin
The surname LOECKE is believed to have originated in Germany, specifically in the northern regions of the country. It likely emerged during the Middle Ages, sometime around the 12th or 13th century.
One theory suggests that LOECKE may have derived from an Old German word "locke," which referred to a lock or curl of hair. This could have been used as a descriptive nickname for someone with curly or unruly hair, which later became a hereditary surname.
Another possibility is that LOECKE is a locational surname, originating from a place name. There are several towns and villages in northern Germany with names similar to Loecke, such as Löcknitz or Lökken. These place names may have been derived from words related to small bodies of water or marshlands.
The earliest recorded instances of the LOECKE surname date back to the 14th century. In 1392, a document from the town of Stendal in Saxony-Anhalt mentions a person named Hans Loecke. Another early reference can be found in the records of the city of Hamburg from 1456, which list a merchant named Hinrich Loecke.
One notable figure with the LOECKE surname was Johann Friedrich Loecke (1673-1737), a German theologian and author who served as a pastor in the town of Werben, near Magdeburg. He published several religious works during his lifetime.
Another individual of historical significance was Karl Friedrich Loecke (1805-1865), a German lawyer and politician who served as a member of the Prussian House of Representatives in the mid-19th century.
In the realm of arts and literature, there was Karl Loecke (1870-1949), a German painter and illustrator known for his landscape paintings and book illustrations.
One of the earliest recorded instances of the LOECKE surname in North America comes from Johann Loecke, who immigrated to Pennsylvania from Germany in 1754.
A more recent figure was Walter Loecke (1888-1954), a German-American engineer and inventor who held numerous patents related to automotive and aircraft technologies.
These are just a few examples of individuals throughout history who carried the surname LOECKE, which has its roots in the northern regions of Germany and likely originated as either a descriptive nickname or a locational surname.
Demographics
Among Census respondents with the surname Loecke, the largest self-reported group is White at 93.1%. The next largest groups are Hispanic (3.9%) and Black (1.0%).
The bar chart below shows how Loecke 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 Loecke surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
