Origin
Meaning and origin of Sustek
The surname SUSTEK is of Czech origin and dates back to the late 15th century. It is derived from the Czech word "sust," which means "a rustling sound," and the suffix "-ek," which is a diminutive form. The name likely originated in the region of Bohemia, now part of the Czech Republic.
One of the earliest recorded instances of the name SUSTEK can be found in the Bohemian land registers from the 16th century. These records document a family with the surname SUSTEK residing in the town of Kutná Hora, an important mining center during that time.
The name SUSTEK may have also been associated with certain occupations or trades related to the production of sound or noise. For instance, it could have referred to someone who worked as a bell ringer or a blacksmith, professions that involved creating distinctive sounds.
In the 17th century, a notable figure with the surname SUSTEK was Jan SUSTEK (1598-1672), a prominent Czech composer and organist who served at the St. Vitus Cathedral in Prague. His works, which included sacred motets and masses, were widely performed and celebrated during his lifetime.
Another individual of note was Václav SUSTEK (1770-1835), a Czech mathematician and astronomer who made significant contributions to the study of celestial mechanics and the calculation of planetary orbits.
Towards the end of the 19th century, a SUSTEK family was documented as living in the town of Žatec, where they owned a brewery and were respected members of the local community.
Over the centuries, variations of the spelling of SUSTEK have emerged, such as SUSTECK, SUSTKA, and SUSTIECK, reflecting the regional dialects and linguistic influences in different parts of the Czech lands.
It is worth noting that several individuals named SUSTEK have achieved recognition in various fields, including Jaroslav SUSTEK (1919-1972), a renowned Czech painter and graphic artist known for his abstract expressionist works, and Jiří SUSTEK (born 1953), a contemporary Czech writer and poet.

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