Origin
Meaning and origin of Baymiller
The surname Baymiller is of German origin, tracing its roots back to the late 15th century in the region of Bavaria. It is a compound name, derived from the German words "baum," meaning tree, and "müller," referring to a miller or someone who operates a mill. This suggests that the name may have originated from an occupation or a particular location associated with a mill near trees or a wooded area.
One of the earliest recorded instances of the name Baymiller can be found in the town records of Augsburg, Bavaria, where a certain Johannes Baymiller is mentioned as a resident in 1487. The name also appears in various historical documents from the 16th and 17th centuries in the regions of Franconia and Swabia, which were part of the Holy Roman Empire at the time.
During the 18th century, the Baymiller name began to spread beyond the borders of Bavaria and the German-speaking territories. This was likely due to the migration of families seeking new opportunities or fleeing religious persecution. In 1736, a Johann Baymiller is recorded as having settled in the town of Strasbourg, which was then part of the French province of Alsace.
Notable individuals bearing the Baymiller surname include Johann Georg Baymiller (1762-1838), a German composer and organist who served at the court of the Prince-Bishop of Würzburg. Another prominent figure was Friedrich Baymiller (1820-1894), a Bavarian politician and member of the Reichstag, the parliament of the German Empire.
Other individuals of note include the Austrian painter Franz Baymiller (1851-1929), whose works can be found in various museums and galleries across Europe, and the German-American entrepreneur Wilhelm Baymiller (1865-1942), who founded a successful brewing company in Milwaukee, Wisconsin, in the late 19th century.
Additionally, there is a record of a Johann Baymiller serving as a soldier in the Prussian Army during the Napoleonic Wars, specifically mentioned in a muster roll from the Battle of Leipzig in 1813.
While the name Baymiller is not as common as some other German surnames, it has a rich history spanning several centuries and can be traced back to its origins in the southern German regions of Bavaria and the surrounding areas.

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.

Keep in mind that these are self-reported numbers.
