Origin
Meaning and origin of Tedeschi
The surname Tedeschi originates from Italy and has its roots in the medieval period. It is derived from the Italian word "tedesco," which means "German" or "of German origin." This suggests that the name was initially given to individuals or families who had German ancestry or connections.
During the Middle Ages, Italy experienced a significant influx of German settlers, merchants, and artisans, particularly in the northern regions. The Tedeschi name may have been assigned to these German immigrants or their descendants to distinguish them from native Italians.
One of the earliest recorded instances of the Tedeschi name can be found in the historical archives of Florence, where a certain Giacomo Tedeschi was mentioned as a merchant in the 13th century. Additionally, the name appears in various medieval documents and records from cities like Venice, Genoa, and Milan, reflecting the presence and influence of German communities in those areas.
In the 14th century, a renowned Italian mathematician and astrologer, Giovanni Tedeschi, better known as Giovanni da Parma, gained recognition for his contributions to the field of mathematics. He was born in Parma around 1305 and is believed to have studied at the University of Bologna.
Another notable figure with the Tedeschi surname was Niccolò Tedeschi, a 15th-century Italian painter from Venice. He was active during the Renaissance period and is known for his religious paintings and frescoes adorning churches in Venice and its surrounding areas.
In the 16th century, the Tedeschi family held a prominent position in the city of Verona. Girolamo Tedeschi, born in 1540, was a respected scholar and professor of law at the University of Padua. His works on legal theory and Roman law were widely studied and influential during that time.
Another notable individual with the Tedeschi surname was Francesco Tedeschi, a 17th-century architect from Rome. He is credited with designing several notable churches and palaces in the city, including the Church of San Giovanni dei Fiorentini and the Palazzo Spada.
The Tedeschi name can also be found in various historical records and documents from other regions of Italy, such as Tuscany, Lombardy, and Piedmont, further suggesting the widespread presence and integration of German communities throughout the Italian peninsula during the medieval and Renaissance periods.

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

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Tedeschi (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. 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.
