Origin
Meaning and origin of Glumm
The surname "GLUMM" has its origins in the Germanic regions of central Europe, tracing back to the early medieval period around the 8th century AD. The name is thought to derive from an Old Germanic word meaning "gloomy" or "sullen," likely referring to a person's temperament or countenance.
One of the earliest recorded instances of the name can be found in the Codex Augiensis, a 9th-century manuscript from the Abbey of Reichenau in present-day Germany. It mentions a certain "Glummarus de Wormacia," which suggests the name was present in the city of Worms during that time.
During the High Middle Ages, the name appears in various charters and records across the Holy Roman Empire, with spellings such as "Glum," "Glumm," and "Glummer." A notable example is Reinher Glumm, a knight from the Palatinate region, who was documented as participating in the Sixth Crusade in 1228-1229.
As the name spread throughout the Germanic lands, it also gave rise to various place names. In the 14th century, a village called "Glummdorf" (Glumm's village) is mentioned in documents from the Duchy of Bavaria. This suggests that the name had become established as a family name by that point.
One of the earliest recorded individuals with the surname "GLUMM" was Johannes Glumm, a merchant and alderman in the Hanseatic city of Lübeck, who lived from around 1380 to 1447. Another notable figure was Albrecht Glumm, a Protestant reformer and theologian from Saxony, who was born in 1492 and played a role in the Reformation movement.
In the 16th century, the name appears in records from various regions of Germany, including the Palatinate, Württemberg, and the Rhineland. For example, Matthias Glumm was a mayor of the town of Speyer in the 1550s, and Hans Glumm was a landowner in the village of Flehingen in Württemberg in the late 1500s.
As the name spread further, it also found its way to other parts of Europe. In the 17th century, there are records of individuals named "GLUMM" in the Netherlands, including a merchant named Jan Glumm who lived in Amsterdam in the 1650s.
While not as prominent as some other surnames, the name "GLUMM" has persisted throughout history, carried by individuals from various walks of life, including merchants, landowners, clergy, and local officials across the German-speaking regions of Europe.
Demographics
Ancestry and ethnicity for Glumm

The bar chart below shows how Glumm 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 Glumm surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
