Origin
Meaning and origin of Udulutch
The surname UDULUTCH has its origins in the Bavarian region of Germany, dating back to the 15th century. It is believed to have derived from the Old German words "udal" meaning "allodial" or "freehold property" and "lutch" meaning "small forest" or "wooded area." The name likely referred to individuals who lived near or owned a small forested area.
One of the earliest recorded instances of the UDULUTCH name can be found in the Landbücher of Bavaria from the late 1400s, which documented land ownership and taxation records. The name appears to have been concentrated in the central Bavarian regions around the cities of Augsburg and Ingolstadt during this time period.
In the 16th century, the UDULUTCH name began to spread beyond Bavaria, with records indicating individuals with this surname residing in various parts of the Holy Roman Empire, including present-day Austria and Switzerland. A notable figure from this era was Hans UDULUTCH (1521-1598), a prominent merchant and landowner in the city of Nuremberg.
By the 17th century, the name had also found its way into the Low Countries, with variations such as UDULUTSCH and UDULUTSCHE appearing in Dutch and Flemish records. One of the earliest documented examples from this region is Pieter UDULUTSCHE (1612-1678), a wealthy trader and ship owner based in Amsterdam.
In the 18th and 19th centuries, the UDULUTCH surname continued to be present across Central Europe, with several individuals of note. These include Johann UDULUTCH (1734-1802), a renowned clockmaker from the Black Forest region of Germany, and Karl UDULUTCH (1816-1890), an Austrian botanist and professor at the University of Vienna.
Another prominent figure bearing this surname was Friedrich UDULUTCH (1857-1932), a German philosopher and author who wrote extensively on the concept of "allodial freedom" and its relation to property rights, perhaps an interesting connection to the name's etymological roots.
While the UDULUTCH name has remained relatively uncommon throughout history, it has persisted across various regions of Europe, particularly in Germany, Austria, and the Low Countries, with occasional instances appearing in other parts of the continent as well.

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