Origin
The surname Bloesch has its origins in the German-speaking regions of Europe, specifically in Switzerland and parts of southern Germany. The name likely emerged in the late medieval period, around the 13th or 14th century.
One theory suggests that Bloesch is derived from the Old High German word "bluozen," which means "to bloom" or "to blossom." This could indicate that the name was originally an occupational surname given to individuals involved in horticulture or gardening professions. Alternatively, it may have been a descriptive surname referring to someone who lived near a blooming meadow or field.
Another possible origin of the name Bloesch is that it evolved from a place name or a topographic feature. In Switzerland and parts of Germany, there are several locations with names containing the root "Bloes" or "Blösch," which could have served as the basis for the surname.
The earliest recorded instances of the Bloesch surname can be found in Swiss historical records from the 15th and 16th centuries. One notable example is Johann Bloesch, a Swiss Protestant reformer born in Zurich in 1499, who played a significant role in the Swiss Reformation movement.
In the 17th century, the surname appears in various German-language documents and manuscripts, including references to individuals such as Hans Bloesch, a merchant from Basel, Switzerland, who lived from 1620 to 1689.
During the 18th and 19th centuries, several individuals with the Bloesch surname made notable contributions in various fields. For instance, Johann Jakob Bloesch (1742-1808) was a Swiss painter and engraver known for his landscape paintings and etchings. Another notable figure was Johann Ludwig Bloesch (1792-1855), a Swiss politician and lawyer who served as the President of the Swiss National Council in 1848.
In the realm of literature, the German writer and poet Max Bloesch (1871-1951) gained recognition for his works exploring themes of nature, love, and spirituality. Additionally, the Swiss artist and sculptor Otto Bloesch (1904-1993) gained acclaim for his abstract and figurative sculptures, many of which can be found in public spaces throughout Switzerland.
While the Bloesch surname is primarily associated with Switzerland and southern Germany, it has also spread to other parts of the world through migration and diaspora communities. However, its roots can be traced back to the Germanic regions of Europe and the various historical figures who carried this name throughout the centuries.
Demographics
Among Census respondents with the surname Bloesch, the largest self-reported group is White at 93.6%. The next largest groups are Hispanic (4.5%) and Two or More Races (1.8%).
The bar chart below shows how Bloesch 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 Bloesch 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.
