Origin
The surname Lembeck originated in Germany and can be traced back to the 13th century. It is derived from the Old German words "lembil" meaning "lame" and "bek" meaning "brook" or "stream". This suggests that the name was initially given to someone who lived near a brook inhabited by lame or crippled people.
One of the earliest recorded instances of the name Lembeck is found in a 1284 document from the town of Lemgo in North Rhine-Westphalia, Germany, where a certain Henricus de Lembeck is mentioned. This indicates that the name was already well-established in that region by the late 13th century.
In the 15th century, the name appears in the records of the town of Münster, Westphalia, where a Johann Lembeck is listed as a respected citizen and merchant. This suggests that the family had gained some prominence and social standing by that time.
The Lembeck name is also found in the 16th century records of the Duchy of Cleves, a former state within the Holy Roman Empire. Here, a Gerhard Lembeck is mentioned as a landowner and member of the local nobility.
One of the earliest known bearers of the Lembeck name was Hans Lembeck (1495-1567), a German painter and engraver who was active in Nuremberg during the Renaissance period. His works can be found in various museums across Europe.
Another notable figure was Johann Lembeck (1630-1699), a German theologian and philosopher who served as the rector of the University of Jena from 1688 to 1699. He was a prolific writer and published several works on theology and metaphysics.
In the 19th century, Karl Lembeck (1820-1892) was a prominent German businessman and industrialist who founded the Lembeck Machine Works in Solingen, a major manufacturer of cutlery and tools.
The name Lembeck has also been found in historical records in other parts of Germany, such as Bavaria and Saxony, suggesting that the family had spread to different regions over time.
Demographics
Among Census respondents with the surname Lembeck, the largest self-reported group is White at 90.5%. The next largest groups are Hispanic (5.9%) and Two or More Races (2.3%).
The bar chart below shows how Lembeck 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 Lembeck 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.
