Origin
The surname Jankura has its origins in the Czech Republic, dating back to the late 15th century. It is believed to have originated in the region of Bohemia, which was historically a part of the Kingdom of Bohemia and is now located in the western part of the modern-day Czech Republic.
The name Jankura is thought to be derived from the Czech word "jankura," which means "a small, twisted piece of wood." This suggests that the surname may have initially been used to identify someone who worked with wood, such as a carpenter or a woodcarver.
One of the earliest recorded instances of the name Jankura can be found in the Veleslavín Bible, a Czech translation of the Bible from the late 16th century. The name is mentioned in the book of Numbers, where it is spelled "Jankura."
In the 17th century, the name Jankura appears in several historical records from the region of Bohemia. For instance, a man named Jan Jankura is listed as a resident of the town of Kutná Hora in 1638.
During the 18th century, the name Jankura continued to be prominent in various parts of Bohemia. One notable person with this surname was Václav Jankura (1726-1798), a Czech composer and organist who served as the Kapellmeister (music director) at the Church of St. James in Prague.
In the 19th century, the Jankura surname spread beyond the borders of Bohemia and the Czech lands. For example, a man named Josef Jankura (1837-1912) was a Czech-born painter who spent much of his career working in Vienna, Austria.
Another individual with the surname Jankura who achieved recognition was Alois Jankura (1855-1923), a Czech architect and engineer who was responsible for designing several notable buildings in Prague, including the National Museum and the Rudolfinum concert hall.
As the centuries progressed, the Jankura name continued to be found throughout various parts of the Czech Republic and neighboring regions, with individuals bearing this surname making contributions in various fields, such as art, music, and architecture.
Demographics
Among Census respondents with the surname Jankura, the largest self-reported group is White at 94.8%. The next largest groups are Two or More Races (3.5%) and Hispanic (0.9%).
The bar chart below shows how Jankura 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 Jankura surname at the time of the 2020 Census, not any inherent property of the name itself.
