Origin
The surname Elfner is believed to have originated in Germany, with its earliest recorded instances dating back to the 16th century. The name likely derives from the German word "Elfer," which means "eleven," suggesting a potential connection to families or professions associated with that number.
One of the earliest known references to the Elfner surname can be found in a 1568 document from the town of Nuremberg, where a certain Hans Elfner is mentioned as a member of the local guild of carpenters. This suggests that the name may have initially been associated with skilled tradesmen or artisans in medieval Germany.
In the 17th century, the Elfner name appears in various church records and tax registers across Bavaria and other regions of southern Germany. Notable individuals from this period include Johannes Elfner (1612-1679), a Lutheran pastor and theologian from Augsburg, and Margarethe Elfner (1630-1701), a renowned herbalist and healer from the village of Rothenburg ob der Tauber.
As the centuries progressed, the Elfner surname spread to other parts of Europe, with some families immigrating to countries like Austria, Switzerland, and even as far as Russia. One notable figure from this era was Karl Elfner (1799-1876), a Prussian military officer who fought in the Napoleonic Wars and later served as a city councilor in Berlin.
In the 19th century, the Elfner name can be found in various historical records and documents across central Europe. Johann Elfner (1820-1892), a Bavarian clockmaker, gained recognition for his intricate handcrafted timepieces, while Elise Elfner (1855-1932), a renowned soprano from Vienna, performed in opera houses across Europe and even made appearances in the United States.
As migration patterns shifted in the late 19th and early 20th centuries, some Elfner families ventured to new shores, with notable individuals like Otto Elfner (1868-1944), a German-American engineer who worked on the construction of iconic landmarks like the Brooklyn Bridge and the Statue of Liberty's pedestal.
While the Elfner surname may not be as prevalent today as it once was in its regions of origin, it continues to carry a rich historical legacy, reflecting the diverse contributions of those who bore this name throughout the centuries.
Demographics
Among Census respondents with the surname Elfner, the largest self-reported group is White at 98.2%. The next largest groups are Asian/Pacific Islander (1.8%).
The bar chart below shows how Elfner 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 Elfner 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.
