The history of the last name Reos

The surname REOS is of Spanish origin, emerging in the late 15th century. It is believed to have originated from the medieval Spanish town of Reos, located in the province of Burgos in northern Spain. The town's name is derived from the Latin word "rivus," meaning a small stream or brook, suggesting that the earliest bearers of the surname may have lived near a small waterway.

One of the earliest recorded instances of the surname REOS can be found in the archives of the Monasterio de San Salvador de Oña, a Benedictine monastery located in the Burgos region of Spain. These records, dating back to the late 1400s, mention a certain Pedro de Reos, who was a landowner and benefactor of the monastery.

In the 16th century, the surname REOS began to spread beyond the Burgos region as families migrated to other parts of Spain. Historical records from the time mention a Juan de Reos, born in 1527, who was a soldier in the Spanish army and fought in the Italian Wars under the command of the Holy Roman Emperor Charles V.

As Spain's colonial empire expanded in the Americas, some bearers of the REOS surname ventured across the Atlantic. One notable example is Hernán de Reos, born in 1585 in Seville, who sailed to the Spanish Vice-Royalty of Peru in the early 1600s and became a prominent landowner and mining entrepreneur in the region of Potosí.

In the 17th century, the REOS surname also found its way to the Spanish territories in the Philippines. Records from the Manila Cathedral mention a Friar Diego de Reos, born in 1619 in Santander, Spain, who served as a Catholic missionary and educator in the Philippine archipelago.

As the REOS surname spread throughout the Spanish-speaking world, it underwent various spelling variations, such as Rios, Ríos, and Rios de Reos, reflecting the fluidity of orthography in those times. However, the original spelling of REOS persisted, particularly in the regions of its origin in northern Spain.
