Origin
The surname Fenske originates from Germany, where it first emerged during the medieval period. It is believed to have derived from the Low German word "fenne," which refers to a marshy or swampy area. This suggests that the name may have initially been a descriptive term referring to someone who lived near or worked in such a region.
One of the earliest recorded instances of the name Fenske can be found in the Deutsches Familiennamen-Lexikon, a comprehensive dictionary of German family names. This reference work cites a certain Hermen Fenske, who was documented in the town of Plau in Mecklenburg, Germany, as early as 1419.
In the 16th century, the name Fenske appears in various historical records from the region of Pomerania, which was then part of the German states. For example, a Valten Fenske is mentioned in the town of Stettin (now Szczecin, Poland) in 1535.
As the name spread across German-speaking areas, variations in spelling emerged. Some of these include Fenskey, Fenski, and Fenschen. These alternative spellings likely reflect regional dialects and differences in pronunciation.
One notable individual bearing the Fenske surname was Johann Fenske, a German composer and organist who lived from 1668 to 1732. He served as the court organist for the Duke of Mecklenburg-Schwerin and composed several works for organ and other instruments.
Another historical figure with the Fenske name was Carl Fenske, a German painter and illustrator who was born in 1819 and died in 1882. He is known for his landscape paintings and illustrations of fairy tales and legends.
In the 19th century, the name Fenske can be found in various German-language place names, such as Fenskenhausen, a village in the state of Saxony-Anhalt. This further reinforces the connection between the surname and geographic locations associated with swampy or marshy areas.
Other notable individuals with the Fenske surname include Walther Fenske, a German military officer who served in World War II and was awarded the Knight's Cross of the Iron Cross for his bravery. He was born in 1897 and died in 1962.
Additionally, there was a German-American artist named Hildegard Fenske, who was born in 1899 and died in 1990. She was known for her abstract expressionist paintings and worked primarily in New York City.
Demographics
Among Census respondents with the surname Fenske, the largest self-reported group is White at 92.6%. The next largest groups are Hispanic (3.3%) and Two or More Races (2.6%).
The bar chart below shows how Fenske 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 Fenske 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.
