Show ContentsWilhelmi History, Family Crest & Coats of Arms

The German state of Prussia, which reached the zenith of its power in the late 19th century, is the glorious birthplace of the distinguished surname Wilhelmi. In the medieval era, after the fall of the Roman Empire, the German lands were inhabited by a variety of Barbarian tribes. The borders of the Barbarian kingdoms changed frequently, but the region that became known in Prussia was roughly divided between the areas of Brandenburg-Prussia, West Prussia, and East Prussia. The colorful history of Brandenburg-Prussia, which is essentially the birthplace of modern Germany, provides a glimpse at the oldest origins of the Wilhelmi family.

Early Origins of the Wilhelmi family

The surname Wilhelmi was first found in northern Germany, where the name was associated in early mediaeval times with the feudal society which would become prominent throughout European history. The name would eventually emerge as belonging to a noble family with great influence, having many distinguished branches, and become noted for its involvement in social, economic and political affairs. Its use as a Surname must be traced back to its immense popularity as a first name early in the Middle Ages. Indeed, one chronicle mentions a knight's feast in Bayeux around 1171 A.D. in which alone 117 Wilhelms were listed as taking part.

Wilhelmi Spelling Variations

Many cultural groups lived in the German states in medieval times. Each had its own dialect and traditions, and unique variations of popular names. Low German, which is similar to contemporary Dutch, was spoken in Westphalia. German names are characterized by additions such as regional suffixes and phrases that tell something about the origin or background of its original bearer. Further contributing to the variation in German names was the fact that there were no spelling rules in medieval times: scribes recorded names according to their sound. The recorded spelling variations of Wilhelmi include Wilhelm, Wilhem, Wilhelmi (Latinized), Wilhelmy, Wilhelmus (Latinized), Wilhelms, Wilhelmsen (Holstein), Wilhalm (Bavaria, Austria), Wilms (Friesland) and many more.

United States Wilhelmi migration to the United States +

The state of Prussia was a great influence on the shape of modern Germany. After the Second World War, Prussia's land was divided among the Soviet Union, Poland, East Germany and West Germany and the state was abolished. Some Prussians remained in those countries after the war, while many others migrated to North America in search of a new start. Philadelphia was their primary point of entry to the United States, after which many of them moved on to Ohio, Texas, Illinois, California, New York, and Maryland. A large number of Prussians also migrated to Ontario and the prairie provinces as United Empire Loyalists. Analysis of immigration records has shown some of the first Wilhelmis to arrive in North America, and among them were:
