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 Wilhelmus. 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 Wilhelmus family.

Early Origins of the Wilhelmus family

The surname Wilhelmus 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.

Wilhelmus 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.
