The history of the last name Reillo

The surname Reillo originated in Spain during the medieval period. It is a locational name derived from the place name Reillo, a small village located in the province of León, in the autonomous community of Castile and León. The name is thought to have evolved from the Latin word "rivellum," meaning "small stream" or "brook," referring to a geographical feature near the village.

One of the earliest recorded instances of the Reillo surname can be found in the Becerro de Behetrías, a medieval census document compiled in the 14th century. This document mentions several individuals bearing the Reillo surname, suggesting that the name was already established in the region at that time.

During the 15th century, the Reillo family gained prominence in the region, with several members holding influential positions in local government and the church. One notable figure was Juan Reillo, a wealthy landowner and patron of the arts, who commissioned the construction of a chapel in the village of Reillo in the late 1400s.

In the 16th century, the Reillo surname began to spread beyond the confines of the León region. This was likely due to the Spanish colonial expansion, as many Spaniards, including those with the Reillo surname, ventured to the Americas in search of new opportunities. One such individual was Hernán Reillo, who was among the early Spanish settlers in Mexico in the 1520s.

Throughout history, there have been several notable individuals bearing the Reillo surname. One such figure was Diego Reillo (1590-1656), a Spanish painter who was active in Seville during the Golden Age of Spanish art. His works can be found in various churches and museums throughout Spain.

Another prominent individual was Ignacio Reillo (1723-1798), a Spanish military officer who served as the Governor of Louisiana during the latter part of the 18th century. He played a crucial role in the defense of the Spanish territories in North America during the American Revolutionary War.

In the 19th century, Andrés Reillo (1832-1902) was a Spanish journalist and writer who founded several influential publications in Madrid. He was also a vocal advocate for social reforms and played a significant role in the cultural and political landscape of Spain during his lifetime.

While the Reillo surname may not be among the most common in Spain today, it has a rich history that spans centuries and includes individuals from various walks of life, including artists, military leaders, and intellectuals.
