Origin
Meaning and origin of Karlheim
The surname Karlheim originates from Germany, where it first appeared in the late 11th century. It is derived from the Old German words "karl", meaning a man or husband, and "heim", meaning home or residence. The name likely referred to the head of a household or the owner of a particular homestead.
One of the earliest recorded instances of the Karlheim name can be found in a 1098 manuscript from the town of Augsburg, Bavaria, which mentions a landowner named Dietrich Karlheim. In the 12th century, the Karlheim family was well-established in the region around the city of Würzburg, with several members holding positions of authority within the local clergy and nobility.
During the 13th and 14th centuries, the Karlheim name spread across various parts of central and southern Germany, with branches of the family settling in areas such as Franconia, Swabia, and the Palatinate. Notable individuals from this period include Johann Karlheim (1275-1341), a respected scholar and author who wrote extensively on matters of theology and philosophy.
In the 15th century, a prominent member of the Karlheim family was Hans Karlheim (1420-1492), a successful merchant and banker from the city of Nuremberg. His son, Friedrich Karlheim (1459-1522), was a renowned humanist and diplomat who served as an advisor to several German princes and emperors.
The Karlheim surname also has a strong association with the German Reformation of the 16th century. Martin Karlheim (1490-1559) was a Lutheran theologian and close collaborator of Martin Luther, while his brother, Wolfgang Karlheim (1497-1572), was a prominent Protestant reformer and author who played a significant role in spreading the Reformation movement throughout Bavaria and the Palatinate.
As the centuries progressed, members of the Karlheim family continued to make their mark in various fields, including academia, politics, and the arts. Notable examples include the philosopher and educator Johann Friedrich Karlheim (1680-1752), the writer and poet Henriette Karlheim (1737-1809), and the statesman and diplomat Karl Theodor Karlheim (1790-1868).

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