Origin
Meaning and origin of Sigwarth
The surname SIGWARTH is of German origin, with roots dating back to the Middle Ages. It is believed to have originated in the region of Bavaria, where it was first documented in the 13th century. The name is derived from the Old German words "sigu," meaning victory, and "wart," meaning guard or watchman.
One of the earliest recorded instances of the name SIGWARTH can be found in a medieval manuscript from the town of Augsburg, dated around 1275. In this document, a man named Hans SIGWARTH is mentioned as a landowner and member of the local nobility.
During the 14th and 15th centuries, the name SIGWARTH began to spread across parts of southern Germany and Austria. Several notable individuals bearing this surname emerged during this period, including Wilhelm SIGWARTH (1380-1448), a renowned scholar and theologian who taught at the University of Vienna.
In the 16th century, a branch of the SIGWARTH family settled in the region of Saxony, where they became prominent landowners and merchants. One of the most famous SIGWARTHS from this era was Johann SIGWARTH (1525-1592), a successful entrepreneur and financier who amassed a considerable fortune through his business ventures.
The SIGWARTH name also appears in several historical records from the 17th and 18th centuries, including church registers and military documents. For example, Hans SIGWARTH (1645-1712) was a respected officer in the Prussian army, serving under King Frederick William I during the early years of the Prussian monarchy.
Another noteworthy SIGWARTH was Katharina SIGWARTH (1718-1795), a celebrated painter and portraitist who gained recognition for her exquisite depictions of the nobility and wealthy merchants of her time.
As the SIGWARTH family continued to spread throughout Germany and neighboring regions, the name underwent various spelling variations, such as SIGWART, SIGWART, and SIGWARDT. However, the original spelling of SIGWARTH remained the most prevalent and widely used form.
Throughout the centuries, the SIGWARTH surname has been associated with individuals from diverse backgrounds, including scholars, artists, military leaders, and entrepreneurs, all of whom have contributed to the rich tapestry of German history and culture.

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