Origin
The surname Blasiman originates from Germany, with its earliest recorded examples dating back to the 16th century. It is believed to have derived from the German word "blasen," which means "to blow," likely referring to an occupation such as a glassblower or musician.
The earliest known record of the Blasiman name appears in the town records of Heidelberg, Germany, in the year 1562, where a certain Hans Blasiman was listed as a glassblower. This suggests that the name may have initially been an occupational surname, given to those who worked with glass or musical instruments.
Throughout the following centuries, the Blasiman name can be found scattered across various regions of Germany, including Bavaria, Saxony, and Brandenburg. Variations in spelling, such as Blasemann and Blaseman, were also common during this time period.
One notable historical figure bearing the Blasiman surname was Johann Blasiman (1620-1689), a renowned glassblower from Nuremberg. His works were highly sought after by nobles and artisans throughout Europe, and his techniques influenced generations of glassmakers.
Another individual of note was Katharina Blasiman (1725-1802), a respected midwife and herbalist from the village of Rothenburg ob der Tauber. Her knowledge of traditional remedies and her compassionate care for mothers and infants earned her a reputation that extended far beyond her local community.
In the 19th century, the Blasiman name found its way to other parts of Europe and beyond, as families emigrated in search of new opportunities. One such individual was Friedrich Blasiman (1845-1921), who left Germany for the United States in the 1870s and settled in the state of Wisconsin, where he worked as a musician and teacher.
Another notable figure was Maria Blasiman (1879-1954), a talented artist from Vienna, Austria, whose paintings and sculptures captured the essence of everyday life in the early 20th century. Her works were exhibited in galleries across Europe and garnered widespread acclaim.
Finally, Hans Blasiman (1905-1985), a German-born engineer, made significant contributions to the field of aeronautics during his career. He worked for several prominent aircraft manufacturers and held several patents for his innovative designs.
While the Blasiman surname may not be as common today, its rich history spans centuries and continents, reflecting the diverse occupations, talents, and achievements of those who have carried this name throughout the ages.
Demographics
Among Census respondents with the surname Blasiman, the largest self-reported group is White at 98.2%. The next largest groups are Black (1.8%).
The bar chart below shows how Blasiman 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 Blasiman surname at the time of the 2020 Census, not any inherent property of the name itself.
