The history of the last name Isquierdo

The surname Isquierdo is of Spanish origin, derived from the Spanish word "izquierdo," meaning "left-handed" or "left." The name likely emerged in the medieval era, initially used to distinguish individuals based on their left-handedness, which was considered unusual at the time.

In the 13th century, the name Isquierdo appeared in various regions of Spain, including Castile, Aragon, and Catalonia. It is believed to have originated from the Latin term "sinister," which translates to "left" or "unlucky." However, the negative connotation associated with left-handedness gradually diminished over time.

One of the earliest recorded instances of the Isquierdo surname can be found in the Cartulario de San Millán de la Cogolla, a 12th-century manuscript that documented land grants and privileges in the Kingdom of Navarre. This reference suggests that the name was already in use during that period.

In the 14th century, the name Isquierdo gained prominence when Juan Isquierdo served as a chamberlain to King Alfonso XI of Castile (1311-1350). Juan's service to the crown demonstrated the rising social status of those bearing the Isquierdo name.

Another notable figure was Rodrigo Isquierdo, a 15th-century nobleman from Seville, who played a significant role in the Spanish conquest of the Canary Islands. His military exploits and leadership during the campaigns against the indigenous Guanches earned him recognition and land grants in the newly conquered territories.

During the Golden Age of Spanish literature, the poet and playwright Lope de Vega (1562-1635) included characters with the surname Isquierdo in several of his works, reflecting the prevalence of the name in Spanish society at the time.

In the 18th century, José Isquierdo (1733-1808) was a renowned Spanish painter known for his religious works and portraits. His artistic achievements elevated the Isquierdo name within the realm of Spanish art and culture.

As the Spanish Empire expanded across the Americas, the Isquierdo surname accompanied the colonists and conquistadors. Notable figures included Diego Isquierdo, a 16th-century explorer who participated in the conquest of Mexico alongside Hernán Cortés, and Alonso Isquierdo, a 17th-century settler in New Spain (present-day Mexico) who established a successful hacienda and became a prominent landowner.
