Origin
Meaning and origin of Keuler
The surname KEULER is of German origin, arising in the late medieval period. It is believed to be derived from the Old High German word "kiulan," which means "to chew or gnaw." This suggests that the name may have originally referred to someone with a particular eating habit or occupation related to food preparation.
The earliest known record of the KEULER surname dates back to the 13th century, where it appeared in various spelling variations such as Keuler, Kuyler, and Kuhler. These variations likely emerged due to regional dialects and the inconsistencies in written records during that time.
One of the earliest documented individuals with this surname was Johannes Keuler, a merchant from the city of Cologne, who was mentioned in a trade register from the year 1287. Another notable figure was Friedrich Keuler, a stonemason who worked on the construction of the famous Strasbourg Cathedral in the early 14th century.
In the 16th century, the KEULER name appeared in the records of the Palatinate region of Germany, where it was associated with several families of millers and bakers. This connection to the milling and baking trades further supports the theory of the name's origin related to food preparation.
One of the most renowned individuals with the KEULER surname was Johann Keuler, a German astronomer and mathematician who lived from 1571 to 1639. He made significant contributions to the field of celestial mechanics and is best known for his work on the laws of planetary motion.
Another notable figure was Philipp Keuler, a German composer and organist who lived from 1648 to 1714. He was renowned for his sacred music compositions and served as the court organist for the Prince-Bishop of Münster.
In the 18th century, the KEULER name gained prominence in the region of Hesse, where several families were involved in the wine-making industry. One such individual was Johann Friedrich Keuler, a renowned vintner who lived from 1725 to 1798 and was known for his exceptional Riesling wines.
While the KEULER surname is not as common today, it has a rich history rooted in various regions of Germany, with connections to trades such as milling, baking, and wine-making, as well as notable individuals in the fields of astronomy, music, and commerce.

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