The Lorentzen arms were recorded in Germany, c. 1765.
Arms such as these were typically recorded in Bavaria.
Bavaria was a country of old landed families and walled market towns. Estates passed down the same line for centuries, and both the landowners and the leading townsmen kept arms, which is why so many Bavarian names sit in the registers.
This is where the arms were entered in the register. Families often moved to other parts of the country, so the same name can turn up in more than one region.
In the Holy Roman Empire, coats of arms were often granted to individuals by the Emperor or his representatives. These arms were then passed down through the generations to all legitimate descendants of the original holder. Younger branches of a family usually kept the same shield design without needing to change it, as the arms belonged to the entire lineage.
The surname Lorentzen is a patronymic name, which means it was originally formed by adding a suffix to the given name Lorenz. This name is the German version of the Latin name Laurentius, which translates to someone who comes from the town of Laurentum or someone who is crowned with laurel leaves. By the time the family was documented in Bavaria in 1765, the name had already been established for generations across various Germanic regions. During this era, families often lived in small agricultural communities where they were identified by their father’s first name to distinguish them from neighbors. As the family moved through the Bavarian landscape, they likely worked as skilled tradespeople or farmers, contributing to the local economy of the Holy Roman Empire. The transition from a simple given name to a permanent family surname reflects the way German society began to organize its population for tax and census purposes during the eighteenth century.

Blazon (the actual original written record)“D'or à une marque de marchand de sa. en forme de deux triangles vidés, l'un sur l'autre, le premier renv., s'entretouchant ; ladite marque soutenue d'un tertre de sin. et sommée d'un 4 de sa., et un fer de rabot d'arg. en fasce, br. sur le point de contact des triangles. C.: un homme iss., hab. d'un parti de sa. et d'or, tenant de sa main dextre un gril carré de sa. à manche du même et de sa sen. un livre ouv. d'arg L. d'or et de sa.”

The Lorentzen arms were recorded in Bâle, c. 1745.
This is where the arms were entered in the register. Families often moved to other parts of the country, so the same name can turn up in more than one region.
In Switzerland, coats of arms were not restricted to the nobility and were often adopted by common citizens and families. These symbols were passed down through generations to show family identity. When branches of a family grew, they often changed small details of the design to distinguish their own line from the original group.
The family name Lorentzen carries a rich history that traces back to the vibrant city of Basel, Switzerland, where records confirm the family’s presence as early as 1745. During the mid-18th century, Basel served as a major center for trade and intellectual exchange in Europe. Families like the Lorentzens often integrated into the local urban structure by participating in the city's guild system or engaging in the flourishing textile and banking industries that defined the region. The name itself is a patronymic, meaning it was derived from the given name Laurentius, which signifies that the family likely established its identity during a period when surnames were becoming formal requirements for legal and tax purposes. By settling in Basel, the early members of this family became part of a sophisticated society that valued education and civic duty, allowing them to contribute to the unique cultural tapestry of the Swiss Confederation.
Derived from the Latin word for the laurel tree or laurel wreath.
