Origin
The surname Keefer has its origins in Germany, dating back to the 13th century. It is derived from the German word "küfer," which refers to a person who makes or repairs wooden casks, barrels, or tubs. The earliest recorded spelling of the name is found in the German town of Esslingen in 1283, where a certain "Conrad der Kufer" is mentioned in official records.
In the 14th century, the name Keefer began appearing in various regions of Germany, such as Bavaria and Saxony. During this period, it was often spelled as "Kufer" or "Kuffer." The name's association with the coopers' trade made it a common occupational surname among those involved in the production and maintenance of wooden vessels.
The Keefer surname is also found in historical records from the Netherlands and Switzerland, where it is believed to have been introduced by German immigrants or traders. In the Dutch city of Amsterdam, a registry from 1492 mentions a "Jan Kuyffer," which is likely an early variant of the name.
As the Keefer family spread across Europe, the name underwent various spelling changes, including "Keffer," "Kiefer," and "Küffer." One notable individual bearing this surname was Johann Kiefer (1616-1690), a German Lutheran theologian and writer who authored several religious works.
In the 17th century, the Keefer surname made its way to America, where it was often anglicized to "Keefer" or "Keffer." Among the earliest recorded instances is that of Hans Kiefer, who arrived in Pennsylvania from Germany in 1732.
Over the centuries, the Keefer name has been associated with a number of notable individuals, including:
1. Johann Kiefer (1616-1690), German Lutheran theologian and writer.
2. Samuel Keffer (1725-1789), American soldier and Indian agent during the Revolutionary War.
3. Charles Kiefer (1824-1892), German-American architect who designed several prominent buildings in Milwaukee, Wisconsin.
4. Ludwig Kiefer (1846-1923), German painter known for his landscapes and genre scenes.
5. Walter Keefer (1914-1986), American actor who appeared in numerous films and television shows throughout his career.
While the Keefer surname has its roots in the German language and the coopers' trade, it has since become an established surname in many countries around the world, with a rich history spanning several centuries.
Demographics
Among Census respondents with the surname Keefer, the largest self-reported group is White at 92.4%. The next largest groups are Two or More Races (2.8%) and Hispanic (2.6%).
The bar chart below shows how Keefer 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 Keefer 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.
