Origin
The surname Modahl has its origins traced back to Germany and Scandinavia. It is believed to have derived from the Old Norse word "modhaull," which means "brave" or "courageous." This name was likely given to individuals who displayed these qualities or to warriors who fought bravely in battles.
In the early medieval period, the name was found in various regions of present-day Germany and the Scandinavian countries. Historical records from the 11th and 12th centuries mention individuals with the name Modahl, although the spelling variations were common during that time, including Modhall, Modhaul, and Modhul.
One of the earliest recorded instances of the name Modahl can be found in the Codex Diplomaticus, a collection of medieval documents from Schleswig-Holstein in northern Germany. The document, dated around 1190, mentions a nobleman named Henricus Modahl, who owned land in the region.
During the 13th century, the name appeared in several Icelandic sagas and manuscripts, indicating its presence in Scandinavia. One notable figure was Thorvald Modahl, an Icelandic explorer who was part of the Viking expeditions to Greenland and Vinland (present-day Newfoundland, Canada) in the late 10th century.
In the 15th century, the name Modahl was associated with a prominent family in the city of Lübeck, a major trading center in northern Germany. Johan Modahl (1425-1498) was a wealthy merchant and prominent member of the Hanseatic League, a powerful commercial and defensive confederation of merchant guilds and market towns in Central and Northern Europe.
Another notable figure was Christoph Modahl (1555-1622), a German astronomer and mathematician who made significant contributions to the study of celestial mechanics and the development of the Gregorian calendar.
In the 18th century, the name Modahl gained recognition through the work of Johann Georg Modahl (1711-1778), a German botanist and physician who made important discoveries in the field of plant taxonomy and classification.
As people migrated from Germany and Scandinavia to other parts of the world, the surname Modahl spread to different regions. Examples of individuals with this surname can be found in various historical records, including Hans Modahl (1879-1957), a Norwegian-American engineer and inventor, and Edith Modahl (1876-1942), a Swedish-American educator and philanthropist.
Demographics
Among Census respondents with the surname Modahl, the largest self-reported group is White at 98.0%. The next largest groups are American Indian/Alaska Native (1.0%) and Two or More Races (1.0%).
The bar chart below shows how Modahl 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 Modahl 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.

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.
