Origin
The surname Spannaus originated in Germany, tracing its roots back to the late 16th century. It is believed to have derived from the Old German word "spannen," which means "to span" or "to stretch." This suggests that the name may have initially referred to a profession or occupation related to stretching or spanning materials, such as a weaver or a rope-maker.
One of the earliest recorded instances of the name Spannaus can be found in the parish records of the town of Bremerhaven, located in the northern region of Germany, dating back to the late 1500s. The name appeared in various spellings, including "Spanhaus" and "Spannhausen," reflecting the regional variations in pronunciation and spelling at the time.
In the 17th century, the Spannaus name began to spread across other parts of Germany, particularly in the regions of Saxony and Bavaria. Historical records from this period indicate that several members of the Spannaus family were engaged in various trades, such as blacksmithing, carpentry, and farming.
A notable figure bearing the Spannaus surname was Johann Spannaus (1601-1674), a respected scholar and theologian who served as a professor at the University of Leipzig. His work on biblical exegesis and theological discourse had a significant impact on the academic community of his time.
Another historical figure of note was Friedrich Spannaus (1725-1798), a renowned architect from the city of Dresden. He was responsible for the design and construction of several iconic buildings, including the Frauenkirche, one of Dresden's most famous landmarks, which was sadly destroyed during World War II but has since been meticulously restored.
In the 19th century, the Spannaus name found its way to other parts of Europe, as well as to the Americas, as a result of emigration. One notable individual from this period was Wilhelm Spannaus (1835-1912), a German-American entrepreneur who established a successful brewing company in Milwaukee, Wisconsin, contributing to the city's rich beer-making tradition.
Another prominent figure was Anna Spannaus (1871-1943), a German activist and feminist who played a significant role in the women's suffrage movement. She tirelessly advocated for gender equality and women's rights, leaving a lasting legacy in the fight for social justice.
As the centuries passed, the Spannaus name continued to spread across various regions and cultures, with individuals making their mark in diverse fields, from academia and architecture to business and activism.
Demographics
Among Census respondents with the surname Spannaus, the largest self-reported group is White at 72.6%. The next largest groups are Hispanic (9.7%) and Two or More Races (8.8%).
The bar chart below shows how Spannaus 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 Spannaus 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.
