Origin
The surname Senffner is of German origin, first appearing in historical records around the 13th century. It is believed to have originated in the region of Saxony, derived from the Middle High German term "senef", meaning mustard plant. This suggests the name may have initially been an occupational surname given to those involved in the cultivation or trade of mustard seeds.
One of the earliest known references to the Senffner name can be found in a 14th-century manuscript from the town of Freiberg, Saxony, where a certain "Hans Senffner" is mentioned as a landowner. The name also appears in various tax records and land deeds from the surrounding areas during the same time period.
As the name spread throughout Germany, it underwent several variations in spelling, including Senfner, Sennfner, and Sennfener. These variations likely reflect regional dialects and the inconsistent spelling conventions of the time.
In the 16th century, a notable figure bearing the Senffner name was Johann Senffner, a Lutheran theologian and author born in Saxony in 1528. His works included commentaries on Biblical texts and theological treatises.
Another historical figure with this surname was Friedrich Senffner, a German jurist and legal scholar who lived from 1599 to 1672. He served as a professor of law at the University of Jena and published several influential works on civil and canon law.
In the 18th century, the Senffner name gained prominence in the field of music with Johann Gottlieb Senffner, a German composer and organist born in 1717. He is known for his contributions to the development of the Protestant church cantata.
The 19th century saw the birth of Carl Senffner, a German-American businessman and entrepreneur who played a pivotal role in the development of the brewing industry in the United States. Born in Saxony in 1829, he later emigrated to America and co-founded the Senffner Brothers Brewing Company in Chicago.
Another notable figure from this era was Otto Senffner, a German artist and illustrator born in 1857. He was renowned for his detailed etchings and woodcuts, many of which depicted landscapes and architectural scenes from various German cities.
While the Senffner name has its roots in Germany, it has since spread to other parts of the world, with descendants bearing this surname found in countries such as the United States, Canada, and Australia.
Demographics
Among Census respondents with the surname Senffner, the largest self-reported group is White at 91.2%. The next largest groups are Two or More Races (5.9%) and Hispanic (2.9%).
The bar chart below shows how Senffner 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 Senffner surname at the time of the 2020 Census, not any inherent property of the name itself.
