The name Devion is an anglicized variation of the French name Devienne, which derives from the Gallic word "diu," meaning "god." Its origins can be traced back to the ancient Celtic tribes that inhabited France during the Iron Age, around the 5th century BCE. The name was likely adopted by early Christian communities in the region as a reflection of their faith.

The earliest recorded use of the name Devion dates back to the 9th century CE, when it appears in medieval French records. During this period, it was a popular name among the nobility and upper classes. One notable bearer of the name was Devion de Montfort, a French knight and crusader who fought in the Third Crusade (1189-1192) under King Richard I of England.

In the 12th century, the name gained prominence in religious circles. Devion de Châlons was a French abbot and scholar who served as the head of the Benedictine monastery in Châlons-en-Champagne between 1170 and 1188. His writings on theology and philosophy were widely influential during the High Middle Ages.

As the name spread across Europe, it took on various spellings and forms. In England, it was sometimes rendered as "Devon" or "Devyn," while in Germany, it appeared as "Devian" or "Devion." One notable bearer of the name was Devion von Rheinstein, a German knight and military commander who fought in the Thirty Years' War (1618-1648).

In the 17th century, the name Devion found its way to the New World through French settlers and colonists. One of the earliest recorded instances was Devion Boudreaux, a French-Canadian explorer and fur trader who established a trading post in what is now Minnesota in the 1680s.

Another significant figure was Devion LaSalle, a French-American nobleman and colonist who played a crucial role in the exploration and settlement of the Mississippi River Valley in the late 17th century. He is credited with establishing several settlements, including the city of New Orleans.

As the name spread across different cultures and regions, it continued to evolve and take on new meanings and associations. However, its roots can be traced back to the ancient Celtic tribes of France and their reverence for the divine.
