The name Hobert is believed to have its origins in the Germanic languages, derived from the Old High German word "hoh" meaning "high" or "lofty," and the suffix "-bert," which is derived from the Germanic word "beraht," meaning "bright" or "illustrious." This combination suggests that the name Hobert may have initially been given to individuals who were regarded as having an elevated or distinguished status.

The earliest known references to the name Hobert can be traced back to the 9th century, where it appears in various medieval records and chronicles. One notable mention is in the Annals of Fulda, a historical record compiled by monks in the Benedictine monastery of Fulda, located in present-day Germany. This document mentions a nobleman named Hobert who was involved in a dispute over land ownership in the year 837 AD.

In the 11th century, the name Hobert gained further prominence with the rise of the Normans in England. One of the most famous bearers of the name was Hobert de Beaumont, a Norman nobleman who accompanied William the Conqueror during the Norman Conquest of England in 1066. De Beaumont went on to become the 1st Earl of Leicester and played a significant role in the establishment of Norman rule in England.

Another notable figure with the name Hobert was Hobert Guiscard, a Norman adventurer and military leader who lived from around 1015 to 1085. Guiscard means "the Resourceful" or "the Cunning" in French, and he earned this epithet for his military prowess and successful campaigns in southern Italy and Sicily. He is credited with establishing the Norman Kingdom of Sicily and is considered one of the most influential Norman rulers of his time.

In the 13th century, a French nobleman named Hobert III, Count of Artois, played a significant role in the Eighth Crusade. He was born in 1216 and died in 1285 during the Crusade, where he fought alongside King Louis IX of France.

The name Hobert also has ties to religious history, with one of the most notable figures being Hobert of Molesme, a French Benedictine monk who lived from around 1028 to 1111. He was a reformer and co-founder of the Cistercian Order, a monastic order that played a crucial role in the religious and cultural life of medieval Europe.

While the name Hobert was more prevalent in earlier centuries, it has become less common in modern times, although it continues to be used in various forms and spellings across different cultures and regions.
