Origin
The surname LEIS is believed to have originated in Germany, particularly in the northern regions, during the medieval period. It is thought to be derived from the Old German word "leis," which means "little" or "small." This suggests that the name may have been initially used as a descriptive nickname for someone of diminutive stature or as a way to distinguish between individuals with the same first name.
One of the earliest documented instances of the LEIS surname can be found in the Codex Traditionum Westfalicarum, a medieval manuscript compiled in the 9th century that recorded land transactions in the region of Westphalia. The name appears in various spellings, including "Leis," "Leys," and "Leiss," indicating the fluidity of surname spellings during that time.
In the 13th century, a man named Johannes Leis was recorded as a resident of the town of Münster, which was a prominent ecclesiastical center in the Holy Roman Empire. This provides evidence of the surname's presence in the area during the High Middle Ages.
The LEIS surname has also been linked to several place names in Germany, such as Leisau, a village in the state of Saxony-Anhalt, and Leissigen, a municipality in the district of Oberallgäu, Bavaria. These connections suggest that the surname may have originated as a locative name, derived from the name of a particular place.
Notable individuals with the surname LEIS throughout history include:
1. Johann Heinrich Leis (1758-1831), a German musician and composer from Reutlingen, Württemberg.
2. Friedrich Leis (1806-1878), a German painter and illustrator from Mannheim, Baden.
3. Johann Leis (1856-1932), an Austrian architect best known for designing the Vienna Burgtheater.
4. Hans Leis (1886-1962), a German World War I flying ace credited with 24 aerial victories.
5. Günter Leis (1921-2008), a German actor and theater director who appeared in numerous films and television productions.
While the surname LEIS may have originated from humble beginnings as a descriptive nickname or a locative name, it has been carried by individuals from various walks of life throughout the centuries, contributing to the rich tapestry of German cultural history.
Demographics
Among Census respondents with the surname Leis, the largest self-reported group is White at 90.8%. The next largest groups are Hispanic (4.1%) and Two or More Races (2.5%).
The bar chart below shows how Leis 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 Leis surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Leis (2000, 2010, 2020).
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.
