Origin
Meaning and origin of Lademann
The surname Lademann originates from northern Germany, first appearing in records from the late 16th century. It is derived from the Low German words "lade" meaning "box" or "chest" and "mann" meaning "man", likely referring to an occupation such as a carpenter or woodworker who crafted chests or boxes.
One of the earliest known references to the name can be found in church records from the town of Lübeck, where a Hans Lademann was documented in 1591. The name also appears in various other northern German towns and cities, including Hamburg, Bremen, and Rostock, throughout the 17th and 18th centuries.
In the 19th century, the name began to spread more widely across Germany, with several notable individuals bearing the surname. Johann Lademann (1810-1892) was a prominent German painter and engraver from Berlin, known for his landscapes and cityscapes. Heinrich Lademann (1856-1917) was a German architect who designed several notable buildings in Berlin, including the Charlottenburg Town Hall.
As Germans emigrated to other parts of the world, the name also began to appear in other countries. One early example is Friedrich Lademann (1804-1876), a German-born botanist and teacher who settled in Australia in the mid-19th century and made significant contributions to the study of the country's flora.
Another noteworthy individual with the surname was Paul Lademann (1858-1940), a German-American businessman and philanthropist who founded the Lademann & Co. department store chain in New York City. He was also known for his charitable work, donating significant sums to various educational and cultural institutions.
In the 20th century, the name continued to be associated with notable figures in various fields. Georg Lademann (1906-1993) was a German engineer and inventor who played a key role in the development of early television technology. Ernst Lademann (1920-1998) was a German actor and voice actor, best known for his roles in various television series and films in the latter half of the 20th century.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
