Origin
The surname Spethman is of German origin, tracing its roots back to the Middle Ages. It is believed to have originated in the region of Westphalia, located in the present-day state of North Rhine-Westphalia, Germany. The name is derived from the Old German word "speth," which means "late" or "tardy," and the suffix "-man," signifying a person or individual.
One of the earliest recorded instances of the name can be found in the Cologne Schreinsbücher (record books) from the 14th century, where a certain Heyneman Spethman was mentioned as a resident of the city. This suggests that the name was already in use during that time period.
In the 15th century, there are references to a Hermannus Spethman, who was a scholar and rector of the University of Cologne. He was known for his contributions to the field of philosophy and theology, and his works were widely circulated among intellectual circles of the time.
During the 16th century, the name appears in various records and documents from various regions of Germany, indicating its spread across the country. One notable figure was Johannes Spethman, a Protestant theologian born in Münster in 1535. He played a significant role in the Reformation movement and authored several religious works.
In the 17th century, a prominent individual bearing the surname Spethman was Christoph Spethman, a German painter and engraver born in Fürstenwalde in 1615. His works, particularly his engravings, were highly regarded and can be found in various art collections throughout Europe.
Another noteworthy figure was Johann Spethman, born in Frankfurt in 1688, who was a renowned architect and urban planner. He was responsible for designing several prominent buildings and urban developments in various cities across Germany during the 18th century.
Over the centuries, the Spethman surname has undergone various spellings and variations, such as Spedtman, Spetman, and Spedeman, reflecting the regional differences and linguistic evolution of the German language. However, the core meaning and origin of the name have remained consistent, signifying an individual who was perceived as "late" or "tardy" in some aspect of their life or character.
Demographics

The bar chart below shows how Spethman 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 Spethman 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.
