Origin
Meaning and origin of Dadich
The surname DADICH is believed to have originated from the Czech Republic in the 12th century. It is thought to be derived from the Old Czech word "dada," which means "grandfather" or "ancestor." This suggests that the name may have been given to someone who was perceived as an elder or patriarch within their community.
The earliest known record of the DADICH surname can be found in a medieval manuscript dated back to 1256, which mentions a landowner named Jan DADICH from the village of Moravska Trebova in the present-day Czech Republic. This document suggests that the name was already well-established in the region by the 13th century.
Another notable early reference to the DADICH name comes from the Bohemian Chancery Records of 1389, which lists a nobleman named Vaclav DADICH as a landowner in the town of Litomerice. This record provides evidence that the surname was also present among the nobility during the late medieval period.
One of the earliest known bearers of the DADICH surname was a Czech religious reformer named Jan DADICH (c. 1410-1457), who was a follower of the influential theologian Jan Hus. DADICH played a significant role in the Hussite movement, which sought to reform the Catholic Church in Bohemia.
During the Renaissance period, a notable figure named Jiri DADICH (c. 1530-1592) was a renowned architect and sculptor who designed several churches and castles in the Czech lands. His most famous work is the Church of St. Barbara in Kutna Hora, which is considered a masterpiece of the late Renaissance architecture in Central Europe.
In the 18th century, a military officer named Frantisek DADICH (1732-1801) served in the Austrian army and participated in the Seven Years' War. He rose through the ranks and eventually became a general, earning recognition for his bravery and leadership on the battlefield.
Another prominent individual with the DADICH surname was Karel DADICH (1812-1889), who was a Czech writer and poet during the Czech National Revival. He was known for his contributions to the development of the Czech language and his efforts to promote Czech culture and literature.
Throughout its history, the DADICH surname has been associated with various place names and regions within the Czech Republic, such as Moravska Trebova, Litomerice, and Kutna Hora. The name has also been spelled in various ways, including Dadytsch, Dadytch, and Dadyts, reflecting the linguistic and cultural diversity of the region.

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.
