Origin
Meaning and origin of Dasho
The surname DASHO is believed to have originated in Italy, specifically in the northern regions near the Alps. Its roots can be traced back to the early medieval period, around the 9th or 10th century. The name is thought to be derived from the Italian word "dasso," which means a badger or a bear. This could suggest that the name may have originally been a nickname or a descriptive name given to someone who resembled or exhibited characteristics of these animals.
One of the earliest recorded instances of the name DASHO can be found in the "Codice Diplomatico Longobardo," a collection of historical documents from the Lombard period in Italy, dating back to the 8th century. This suggests that the name has a deep-rooted history in the region.
In the 12th century, a notable figure named Guglielmo DASHO was mentioned in the "Chronicon Novaliciense," a chronicle of the Novalesa Abbey in the Piedmont region of Italy. This record provides evidence of the name's presence during the medieval period.
During the Renaissance era, a prominent Italian scholar and humanist named Giovanni Battista DASHO (1492-1556) gained recognition for his contributions to literature and philosophy. He was born in Pavia and spent a significant portion of his life in Milan, where he taught at the University of Milan.
Another noteworthy individual with the surname DASHO was Antonio DASHO (1634-1697), an Italian painter and architect who was active in the Baroque period. He was born in Genoa and is known for his architectural works, including the design of several churches and palaces in the city.
In the 18th century, a man named Pietro DASHO (1715-1782) gained distinction as a composer and musician. He was born in Turin and composed operas, cantatas, and instrumental works that were performed across Italy during his lifetime.
While the surname DASHO has its roots in Italy, it has since spread to other parts of the world through migration and immigration. However, the historical records and notable figures mentioned above provide insight into the name's origins and its presence throughout various periods in Italian history.

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 Dasho surname at the time of the 2020 Census, not any inherent property of the name itself.
