It is believed to have first emerged in Italy during the late Roman and early Byzantine periods, particularly in regions like Rome, Naples, and Sicily.

One of the earliest recorded instances of the Gregorian surname can be found in the Codex Diplomaticus Cavensis, a collection of medieval documents from the Monastery of Cava in southern Italy, dating back to the 11th century. The name is also mentioned in various other Italian manuscripts and records from the 12th and 13th centuries.

Notable individuals with this surname include Pope Gregory XIII (1502-1585), who introduced the Gregorian calendar in 1582, and Fernan Perez de Oliva Gregorian (1494-1530), a Spanish humanist and philosopher.

In the 18th century, the Gregorian surname spread across Europe and beyond. One notable bearer was Johann Gottfried Gregorian (1688-1770), a German composer and organist. Another was John Gregorian (1713-1791), an English mathematician and astronomer who made significant contributions to the study of celestial mechanics.

As the centuries progressed, the Gregorian surname continued to be associated with individuals from various fields, including the arts, sciences, and literature. Some notable examples include the British painter John Gregorian (1778-1853), the Russian poet and translator Apollon Gregorian (1822-1892), and the American author and journalist Khalil Gregorian (1916-2000).
