The surname Wilhelmi has its origins in medieval Germany, likely deriving from the personal name Wilhelm. The name Wilhelm itself originates from Old High German elements "wil," meaning will or desire, and "helm," meaning helmet, protector.

This surname was primarily found in regions that are now considered parts of Germany, particularly the Holy Roman Empire during the medieval period.
The surname Wilhelmi makes its first historical appearances in medieval documents and records. One of the earliest mentions can be traced back to the 13th century in various ecclesiastical and feudal records of central Europe. The name appeared in a variety of spellings, including Wilhelme and Wilhelmus, due to the lack of standardized spelling during that time. In the chronicled annals of the Holy Roman Empire, a cleric named Ludovicus Wilhelmi was noted in Cologne in the year 1243.
One notable individual bearing the surname was Johannes Wilhelmi, a 14th-century cleric who served as a scribe for the bishopric of Mainz, born around 1300 and active until his death in 1372.

Moving to the 18th century, another prominent bearer of the name was Karl Friedrich Wilhelmi, a respected botanist born in 1769 and who died in 1832. His work included extensive classifications of European flora and added notable contributions to the field of botany.
In the artistic domain, Friedrich August Wilhelmi was a notable composer and musician born in 1797. He was instrumental in the Romantic music movement and continued his work until his death in 1862. His compositions remain celebrated within classical music circles.
