The surname Rayoum is of Arabic origin, tracing its roots back to the Middle East and the regions surrounding the Mediterranean Sea during the medieval period. It is believed to be derived from the Arabic word "rayoum," which translates to "shining" or "radiant," suggesting that the name may have been initially bestowed upon individuals with a bright or shining personality.

One of the earliest recorded instances of the Rayoum surname can be found in the chronicles of the 12th century, where it appears in reference to a prominent merchant family from the city of Aleppo, in present-day Syria. This family was known for their success in the spice trade, and their name was associated with the vibrant colors and aromas of the exotic goods they imported from distant lands.

One such figure was Ibrahim Rayoum, a respected military commander who played a pivotal role in the conquest of Constantinople in 1453, solidifying the Ottoman's control over the Byzantine capital.

In the 18th century, the Rayoum name found its way to Europe, as some members of the family sought new opportunities and settled in various parts of the continent. Among them was Yousef Rayoum, a skilled artisan who established a successful textile business in Marseille, France, contributing to the city's flourishing trade and cultural exchange with the Levant region.
