Origin
Meaning and origin of Delzeith
The surname DELZEITH has its origins in the Germanic regions of central Europe, specifically in the area that is now modern-day Germany. It is believed to have emerged during the Middle Ages, between the 5th and 15th centuries. The name is likely derived from the Old High German word "delz" or "delza," meaning "valley," and the suffix "-eith," which denotes a place or region.
One of the earliest recorded mentions of the name DELZEITH can be found in the Codex Diplomaticus Saxoniae, a collection of medieval documents from the region of Saxony, dating back to the 9th century. This reference suggests that the name was associated with a specific location or landholding in that region.
In the 12th century, there are records of a noble family named DELZEITH residing in the town of Regensburg, in what is now Bavaria. They were known for their involvement in local politics and their service to the Holy Roman Empire. One notable member of this family was Konrad DELZEITH, who served as a knight and participated in the Third Crusade under the command of Emperor Frederick Barbarossa in the late 12th century.
During the 13th century, a branch of the DELZEITH family migrated to the region of Alsace, which at that time was part of the Holy Roman Empire. They established themselves as landowners and merchants in the city of Strasbourg. One prominent member of this branch was Johann DELZEITH, who was a successful wool trader and served as a city councilor in Strasbourg in the late 1200s.
In the 15th century, the name DELZEITH appears in records from the Duchy of Saxony, where a family of that name held lands and titles. One notable figure from this period was Dietrich DELZEITH, who was a knight and military commander in the service of the Elector of Saxony during the Hussite Wars in the early 1400s.
Another notable individual bearing the surname DELZEITH was Hans DELZEITH, a master craftsman and woodcarver who lived in the city of Nuremberg in the late 15th and early 16th centuries. His intricate carvings and woodworks can still be seen in some of the historic churches and buildings in Nuremberg.
While the surname DELZEITH has its roots in the Germanic regions of central Europe, it has since spread to other parts of the world through migration and immigration. However, the details provided here focus primarily on the early history and origins of the name in its Germanic context.

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