The given name Wilbert has its origins in the Germanic languages, where it is a compound name derived from the elements "wil" meaning "will" or "desire," and "berht" meaning "bright" or "shining." This combination results in a name that roughly translates to "brilliant will" or "shining desire." The name's roots can be traced back to the early medieval period, around the 5th to 8th centuries AD, when it first emerged among various Germanic tribes across central and western Europe.

While Wilbert does not appear to have any specific historical references in ancient texts or religious scriptures, it was likely used as a personal name among the Germanic peoples during the early Middle Ages. The earliest recorded examples of the name date back to the 9th and 10th centuries, where it can be found in various medieval records and documents from regions such as modern-day Germany, France, and the Low Countries.
