The history of the last name Castillejos

The surname Castillejos is of Spanish origin, tracing its roots back to the medieval period in the regions of Castile and León. It is derived from the Spanish word "castillo," meaning "castle," and the diminutive suffix "-ejo," which indicates a small or diminished form. This suggests that the name may have originally referred to a person associated with a small castle or fortified structure.

One of the earliest recorded instances of the Castillejos surname is found in the Repartimiento de Sevilla, a document from the 13th century that recorded the distribution of land and properties in Seville after the Christian conquest of the city. This document mentions individuals with the surname Castillejos, suggesting their presence in Andalusia during that time.

In the 15th century, the Castillejos name appeared in historical records from the Kingdom of Aragon, particularly in the region of Valencia. Notable individuals from this period include Juan de Castillejos (1460-1530), a Spanish poet and courtier who served under the Catholic Monarchs, Ferdinand and Isabella.

The Castillejos surname also has connections to the Spanish conquest of the Americas. In the 16th century, Cristóbal de Castillejos (1492-1564) was a Spanish conquistador who participated in the conquest of Mexico alongside Hernán Cortés. He later became an encomendero (holder of an encomienda) in the region of Tlaxcala.

In the 17th century, the Castillejos name was prominent in the region of Extremadura, where the family possessed estates and properties. One notable figure from this era was Diego de Castillejos (1625-1692), a Spanish military officer and colonial administrator who served as the Governor of Panama from 1678 to 1681.

Another notable individual with the Castillejos surname was José María Castillejos (1775-1848), a Spanish military officer and politician who played a significant role in the Peninsular War against the French invasion of Spain. He later served as the Minister of War during the reign of Queen Isabella II.

Throughout history, the Castillejos surname has been associated with various places and regions within Spain, reflecting the movement and settlement patterns of its bearers. Some of these locations include the towns of Castillejo (in Extremadura) and Castillejo de Robledo (in Soria), which may have been named after individuals with the Castillejos surname or due to the presence of small castles in those areas.
