Origin
Meaning and origin of Bluth
The surname BLUTH is of German origin, with its roots dating back to the Middle Ages. The name is believed to have originated from the Old German word "bluot," which means "blood." This connection suggests that the name may have been given to individuals with a ruddy complexion or those associated with occupations involving blood, such as butchers or soldiers.
The earliest recorded instances of the name BLUTH can be traced back to the 13th century in the regions of Bavaria and Saxony. Some of the earliest documented spellings include "Bluther," "Bluter," and "Blutho." These variations reflect the evolution of the name over time and the regional differences in pronunciation and spelling conventions.
In the 14th century, the BLUTH name appeared in various municipal records and chronicles, particularly in the cities of Nuremberg and Leipzig. One notable figure from this period was Hans Bluth, a merchant and landowner who lived in Nuremberg in the late 1300s.
During the 16th and 17th centuries, the BLUTH name gained prominence in various parts of Germany. In 1586, a certain Johann Bluth was recorded as a prominent scholar and theologian in the city of Wittenberg, known for his contributions to the Protestant Reformation.
The 18th century saw the BLUTH name spread to other European countries, including France and England. One notable individual from this period was Friedrich Wilhelm Bluth, a German composer and musician who lived from 1738 to 1812.
In the 19th century, the BLUTH name continued to be found across Germany and other parts of Europe. One notable figure was Karl Bluth, a German painter and illustrator born in 1825 in Dresden, who gained recognition for his landscapes and portraits.
As the BLUTH name spread across Europe and beyond, it also found its way to other parts of the world through migration and immigration. One example is Wilhelm Bluth, a German-born farmer who emigrated to the United States in the mid-19th century and settled in the state of Wisconsin.
Throughout its long history, the BLUTH surname has been associated with various professions and notable figures, from scholars and artists to merchants and farmers. While its origins can be traced back to the Middle Ages in Germany, the name has since become widespread and can be found in many parts of the world.

The bar chart below shows how Bluth 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 Bluth surname at the time of the 2020 Census, not any inherent property of the name itself.
