The history of the last name Mormann

The surname MORMANN is of German origin, with its earliest known roots dating back to the 14th century in the regions of Bavaria and Rhineland. The name is believed to be derived from the Old High German words "mor" and "mann," meaning "moor man" or "man from the moors." This suggests that the name was initially given to individuals who lived or worked in marshy or swampy areas.

One of the earliest recorded instances of the MORMANN surname can be found in the town of Worms, located in the Rhineland-Palatinate region of Germany. In a document dated 1387, a person named Johannes MORMANN is mentioned as a landowner in the area.

During the 16th and 17th centuries, the MORMANN name appeared in various church records and tax registers across Bavaria and the Rhineland. Notable individuals from this period include Hans MORMANN (1542-1612), a respected merchant from Nuremberg, and Margarethe MORMANN (1609-1673), a midwife who lived in the village of Eggermühlen.

As the MORMANN family spread across Germany and neighboring regions, the surname underwent slight variations in spelling, such as MORMAN, MOHRMANN, and MOORMANN. In the late 18th century, a branch of the family settled in the town of Hildesheim, where the name was occasionally recorded as MOORMANN.

One of the most prominent figures with the MORMANN surname was Johann Friedrich MORMANN (1783-1859), a German painter and engraver who was born in Braunschweig and gained recognition for his landscapes and portraits.

Another notable individual was Wilhelm MORMANN (1842-1912), a German industrialist and entrepreneur who founded a successful textile manufacturing company in Krefeld. His son, Carl MORMANN (1870-1936), followed in his footsteps and expanded the family business.

During the 19th century, the MORMANN name also made its way to other parts of Europe and beyond. In France, a family of winemakers from Alsace carried the surname MORMANN, with records showing Jean-Baptiste MORMANN (1812-1879) as a respected vintner in the region.
