Origin
The surname Kiehl originated in Germany, with its roots dating back to the early 16th century. It is believed to have derived from the Old German word "kiel," which referred to a small boat or ship. This suggests that the name may have initially been associated with maritime or fishing occupations.
One of the earliest recorded instances of the Kiehl name can be found in the town of Augsburg, Bavaria, in the year 1534. Records indicate that a certain Hans Kiehl was a respected shipwright and boat builder in the region during that time.
In the late 17th century, the Kiehl surname spread to various parts of Germany, particularly in the northern regions near the North Sea and Baltic coasts. This geographic distribution aligns with the maritime connotations of the name's origin.
Historical documents from the 18th century mention a notable figure named Johann Kiehl (1715-1789), who was a master shipbuilder in the city of Hamburg. His craftsmanship and contributions to the local shipbuilding industry were widely recognized during his lifetime.
The Kiehl name also found its way into the realm of academia and education. In the early 19th century, a renowned scholar and linguist named Friedrich Kiehl (1801-1867) gained recognition for his groundbreaking work on Germanic languages and dialects.
Another significant individual bearing the Kiehl surname was Karl Kiehl (1854-1927), a prominent German architect who designed several iconic buildings in Berlin and other cities during the late 19th and early 20th centuries.
As the name spread across Europe, it underwent various spelling variations, including Kiel, Kiehl, Kühle, and Kühle, reflecting regional dialects and pronunciation differences.
While the surname Kiehl may have originated from maritime roots, over the centuries, it has been associated with individuals from diverse professions and backgrounds, reflecting the rich tapestry of German history and culture.
Demographics
Among Census respondents with the surname Kiehl, the largest self-reported group is White at 93.7%. The next largest groups are Two or More Races (2.6%) and Hispanic (2.2%).
The bar chart below shows how Kiehl 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 Kiehl 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.
