Origin
The surname Konowitz originated in the Prussian region of what is now modern-day Poland and Germany. It is a locational surname derived from the town of Konitz, which is located in the Pomeranian Voivodeship of northern Poland. The name is believed to have emerged in the 13th or 14th century, during the period of German settlement and expansion into the region.
The name Konowitz is thought to have its roots in the Slavic word "konitz," which means "horse" or "horseman." This suggests that the name may have initially been used to identify individuals who worked with horses or were associated with equestrian activities in the area around Konitz.
One of the earliest recorded instances of the name Konowitz can be found in the 1410 Prussian census records, where a man named Hans Konowitz is listed as a resident of the town of Konitz. In the following centuries, the name appears in various historical documents and records throughout the region.
A notable bearer of the Konowitz surname was Johann Konowitz, a German military officer who served in the Prussian army during the Seven Years' War (1756-1763). He was born in 1725 in the town of Konitz and rose through the ranks to become a respected commander.
Another individual with the Konowitz name was Katharina Konowitz, a 16th-century noblewoman from the Pomeranian region. She was recorded as owning significant landholdings in the area around the town of Konitz, which suggests that the Konowitz family held a prominent position in the local society.
In the 18th century, a man named Gottfried Konowitz made a name for himself as a renowned clockmaker and watchmaker in the city of Danzig (now Gdańsk, Poland). His intricate timepieces were highly sought after by wealthy patrons throughout the region.
A notable academic bearing the Konowitz surname was Professor Karl Konowitz, who lived in the late 19th century and was a respected scholar of Slavic languages and literature at the University of Berlin.
It is worth noting that variations in spelling, such as Konowicz, Konowits, and Konowicz, were common throughout the history of this surname due to regional dialects and linguistic changes over time.
Demographics
Among Census respondents with the surname Konowitz, the largest self-reported group is White at 97.2%. The next largest groups are Two or More Races (1.9%) and Asian/Pacific Islander (0.9%).
The bar chart below shows how Konowitz 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 Konowitz surname at the time of the 2020 Census, not any inherent property of the name itself.
