Origin
The surname FALTERSACK originated in the German-speaking regions of Central Europe, likely in the late medieval period around the 13th or 14th centuries. It is believed to derive from the Old German words "falter" meaning a butterfly or moth, and "sack" referring to a sack or bag.
One theory is that the name may have initially referred to an occupation involving the collection or trade of silkworm cocoons, which were sometimes referred to as "Faltersäcke" or butterfly bags. Alternatively, it could have been a nickname for someone who carried a sack or pouch adorned with butterfly motifs.
The earliest known record of the FALTERSACK name appears in a land registry from the town of Rothenburg ob der Tauber in Bavaria, dated 1387, where a certain Hans Faltersack is listed as a landowner. Another early reference is found in the archives of the city of Nuremberg, where a merchant named Konrad Faltersack is mentioned in a trade document from 1426.
In the 16th century, a notable figure bearing this surname was Matthias Faltersack, a Lutheran minister and theologian from Saxony, who lived from around 1520 to 1589. He was known for his sermons and writings defending the Protestant Reformation.
During the 17th century, the FALTERSACK name was also found in the region of Silesia, which was then part of the Holy Roman Empire. One record from 1671 mentions a Johann Faltersack, a farmer and landowner in the village of Strehlen (now part of Poland).
Another individual of note was Christoph Faltersack, a German-born artist and engraver who lived from 1677 to 1737. He worked in various cities across Europe, including Vienna, Prague, and Paris, and is best known for his intricate etchings and engravings depicting landscapes and architectural scenes.
In the 19th century, a prominent figure was Karl Faltersack, a German-Austrian historian and archivist who lived from 1817 to 1888. He worked as the head archivist for the city of Vienna and published several works on the history of Austria and the Habsburg Empire.
While the FALTERSACK name was most prevalent in German-speaking regions, it also spread to other parts of Europe through migration and trade. Over time, variations in spelling and pronunciation emerged, such as Faltersack, Faltersak, and Falterseck.
Demographics
Among Census respondents with the surname Faltersack, the largest self-reported group is White at 97.2%. The next largest groups are Two or More Races (1.9%) and Black (0.9%).
The bar chart below shows how Faltersack 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 Faltersack 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.
