Origin
Meaning and origin of Tandeski
The surname Tandeski has its origins in the ancient Slavic lands of Eastern Europe, tracing back to the 12th century. It is derived from the old Slavic word "tandr," which refers to a person who was a maker or seller of tinder, a material used for starting fires.
One of the earliest recorded mentions of the name can be found in a church record from the village of Tandrevo, located in what is now Belarus, dating back to 1187. The record lists a local resident named Mikhal Tandeski, who was likely a tinder maker by trade.
As the name spread across the region, it evolved into various spellings, such as Tandreski, Tandreski, and Tandrevski, reflecting the local dialects and languages. In the 15th century, the Tandeski family was documented as owning land near the town of Brest, which was then part of the Grand Duchy of Lithuania.
A notable figure bearing the Tandeski name was Ivan Tandeski, a military commander who fought alongside Prince Fyodor Shuisky during the Polish-Muscovite War in the early 17th century. His exploits were recorded in several contemporary chronicles, including the "Khronika Smutnoho Vremeni" (Chronicle of the Time of Troubles).
Another prominent individual was Yelena Tandreskaya, a renowned painter who lived in St. Petersburg in the late 18th century. Her works, primarily portraits of Russian nobility, can be found in several prestigious art collections, including the Hermitage Museum.
In the 19th century, the Tandeski family gained prominence in the field of education. Mikhail Tandeski (1824-1901) was a respected professor of philosophy at the University of Kiev, and his son, Andrei Tandeski (1856-1918), followed in his footsteps, becoming a renowned linguist and author of several influential books on Slavic languages.
During the early 20th century, the Tandeski name was associated with the growing industrial sector in the Russian Empire. Pyotr Tandeski (1879-1942) was a successful businessman and owner of a major steel factory in the city of Chelyabinsk.
Throughout its long history, the Tandeski surname has been carried by individuals from diverse backgrounds, ranging from military leaders and artists to scholars and industrialists, leaving an indelible mark on the cultural and historical fabric of Eastern Europe.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
