Origin
The surname Hammes originated in Germany, tracing its roots back to the 8th or 9th century. It is believed to have derived from the Old German word "ham," which meant "home" or "village." This suggests that the name may have initially referred to someone who lived in a particular hamlet or village.
One of the earliest recorded mentions of the Hammes name can be found in the Codex Diplomaticus Saxoniae, a collection of historical documents from the region of Saxony. This reference dates back to the 11th century, indicating the name's long-standing presence in German history.
During the Middle Ages, the name Hammes appeared in various forms, including Hamme, Hamen, and Hames, reflecting the variations in spelling and pronunciation that were common at the time. It is also possible that the name was associated with certain place names, such as Hamm, a town in North Rhine-Westphalia, Germany.
Notable individuals who bore the Hammes surname throughout history include Johann Hammes (1562-1638), a German Lutheran theologian and author; Hans Hammes (1873-1945), a German politician and member of the Reichstag; and Wilhelmina Hammes (1871-1954), a Dutch painter known for her landscapes and still-life works.
Another figure of historical significance was Peter Hammes (1837-1918), a German-American Catholic priest and educator who played a pivotal role in establishing parochial schools in the Archdiocese of Milwaukee, Wisconsin.
In the realm of literature, the name Hammes is associated with Gerhard Hammes (1927-2003), a German author and poet who was celebrated for his lyrical works, including the collection "Gedichte" (Poems).
It is important to note that the Hammes surname has been carried by individuals from various walks of life, including artists, scholars, politicians, and religious figures, contributing to the rich tapestry of German and European cultural heritage.
Demographics
Among Census respondents with the surname Hammes, the largest self-reported group is White at 93.2%. The next largest groups are Two or More Races (2.8%) and Hispanic (2.1%).
The bar chart below shows how Hammes 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 Hammes 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.
