Origin
The surname Hanneman originates from Germany, with records tracing it back to the 16th century. It is believed to have derived from the German word "Hann," which referred to a person from the region of Hanover or Lower Saxony. The name may also be linked to the medieval personal name "Han" or "Hano."
Early references to the name can be found in various historical documents, such as church records and tax rolls from the late 1500s and early 1600s in northern Germany. One notable mention is in the parish records of Lüneburg, where a Hans Hanneman is listed as a resident in 1612.
The earliest recorded instance of the surname Hanneman is traced back to a document from 1524 in the town of Osnabrück, where a merchant named Gerhard Hanneman is mentioned. This suggests that the name had already been established in the region by the early 16th century.
Throughout history, several individuals with the surname Hanneman have gained recognition in various fields. Johannes Hanneman (1599-1671) was a German jurist and professor of law at the University of Helmstedt. Johann Ludwig Hanneman (1640-1724) was a renowned German portrait painter, renowned for his depictions of royalty and nobility.
In the 19th century, Theodor Hanneman (1832-1904) was a celebrated German landscape painter, known for his romanticized depictions of the Black Forest region. August Hanneman (1865-1932) was a German-American architect who designed several notable buildings in Chicago, including the Heidelberg Building and the Woodlawn Masonic Temple.
Another notable figure was Friedrich Hanneman (1887-1957), a German sculptor and painter who worked in a expressionist style and was associated with the Brücke movement. His works can be found in various museums across Germany.
Throughout the centuries, the surname Hanneman has been spelled in various ways, such as Haneman, Hannemann, and Hanneman, reflecting regional variations and phonetic adaptations. While the name originated in Germany, it has since spread to other parts of the world due to emigration and migration patterns.
Demographics
Among Census respondents with the surname Hanneman, the largest self-reported group is White at 92.5%. The next largest groups are Two or More Races (3.4%) and Hispanic (3.2%).
The bar chart below shows how Hanneman 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 Hanneman surname at the time of the 2020 Census, not any inherent property of the name itself.
