The surname DEAU originated in France during the late medieval period. It is derived from the Old French word "deau" or "deu," which means "of God" or "divine." This name was likely given to someone who was deeply religious or worked in a religious profession, such as a monk or a priest.

The earliest recorded instances of the surname DEAU can be traced back to the 13th and 14th centuries in various regions of France, including Normandy, Brittany, and the Île-de-France. In some historical documents, the name was also spelled as "Deu," "Dieux," or "Dieux-Aides."

One notable historical figure with the surname DEAU was Jacques DEAU (1554-1629), a French Catholic priest and writer who authored several religious works, including a commentary on the Book of Psalms. Another was Jean-Baptiste DEAU (1677-1752), a French architect and engineer who designed several notable buildings in Paris, such as the Church of Saint-Roch.

In the 16th century, the surname DEAU appeared in the Domesday Book, a manuscript record of landholders in England commissioned by William the Conqueror in 1086. This suggests that some individuals with this surname may have migrated from France to England during the Norman conquest.
