The history of the last name Aldaz

The surname ALDAZ has its origins in the Basque region of northern Spain and southern France, dating back to the early medieval period. It is believed to be derived from the ancient Basque word "alde," meaning "side" or "part," combined with the suffix "-az," which was commonly used to form locational surnames.

One of the earliest recorded instances of the ALDAZ surname can be found in the Cartulary of San Millán de la Cogolla, a historic monastery in La Rioja, Spain. This document, dating back to the 11th century, mentions individuals with the surname, indicating its use in the region at that time.

The ALDAZ name is closely linked to the town of Aldaz, located in the Navarrese municipality of Esteribar, Navarre, Spain. It is likely that the surname originated from this specific location, with early bearers taking the name as a way to identify themselves with their place of origin or residence.

Notable individuals with the ALDAZ surname throughout history include:

1. Juan de Aldaz (c. 1520 - c. 1590), a Spanish military officer and conquistador who participated in the conquest of Peru under Francisco Pizarro.
2. Miguel de Aldaz (c. 1570 - c. 1640), a Spanish architect and engineer who designed several notable buildings in Madrid, including the Church of San Ginés.
3. Catalina de Aldaz (c. 1610 - c. 1680), a Spanish nun and mystic who founded the Convent of the Immaculate Conception in Tudela, Navarre.
4. Pedro de Aldaz (c. 1650 - c. 1720), a Spanish painter known for his religious works, particularly those commissioned by the Franciscan Order.
5. Fermín de Aldaz (c. 1790 - c. 1860), a Spanish military officer who fought in the Peninsular War against the French and later served as the Governor of Pamplona.

While the ALDAZ surname has its roots in the Basque region, it has since spread to other parts of Spain, as well as to Latin American countries due to Spanish colonization and migration.
