The history of the last name Díaz-Díaz

The surname DIAZDIAZ originated in Spain during the medieval period. It is a doubled form of the common Spanish surname Diaz, which itself derives from the patronymic "son of Diego." Diego is the Spanish form of the name James, which comes from the Hebrew name Jacob.

DIAZDIAZ likely arose as a way to distinguish different branches of the Diaz family, with the doubled surname indicating a line descended from someone named Diaz who took the surname as their own. Such doubling of surnames was not uncommon in Spain during the Middle Ages.

The village of Diazdiaz in Guadalajara province may have been named after an early bearer of this surname who lived there. However, it's also possible the place name came first and the surname derived from it.

One prominent family with this name were the Diazdiaz de Vivar, who claimed descent from the legendary hero El Cid (full name Rodrigo Diaz de Vivar), who led Christian forces in the Reconquista in the late 11th century. However, the link to El Cid is uncertain.
