Origin
Meaning and origin of Bredemus
The surname BREDEMUS originated in Germany, with records of the name dating back to the 16th century. It is believed to have derived from the Middle Low German words "brede" meaning "broad" and "huus" meaning "house," suggesting the name may have referred to someone who lived in a large or spacious dwelling.
One of the earliest known instances of the BREDEMUS name is found in the baptismal records of St. Peter's Church in Cologne, where a certain Johannes Bredemus was christened in 1569. Another early reference is in the 1602 tax records of the town of Lüneburg, which list a Henrich Bredemus among the local landowners.
The BREDEMUS name was also prevalent in the northern German region of Schleswig-Holstein, with various spellings such as Bredemuß, Bredemuhs, and Bredemos appearing in local church records and legal documents from the 17th and 18th centuries. One notable individual from this area was Hans Bredemus (1609-1679), a prosperous merchant and alderman in the city of Flensburg.
As the centuries passed, members of the BREDEMUS family dispersed across Germany and into neighboring countries. In the late 19th century, a Johann Bredemus (1847-1923) from Saxony gained recognition as a respected architect and urban planner, contributing to the design of several public buildings and city squares in Dresden and Leipzig.
Another noteworthy figure was the scholar and philosopher Wilhelm Bredemus (1876-1957), who taught at universities in Berlin and Heidelberg and authored several influential works on metaphysics and epistemology.
Across the Atlantic, the BREDEMUS name also took root in the United States, with immigrants arriving from Germany in the mid-19th century. One early American bearer was Johann Bredemus (1825-1901), who settled in Pennsylvania and became a prominent figure in the local German-American community.

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