The history of the last name Simancas

The surname Simancas originated in Spain, specifically in the town of Simancas, located in the province of Valladolid, in the Castile and León region. The name is derived from the Latinized version of the town's name, "Septemancas," which means "seven curves" or "seven bends," likely referring to the winding course of the nearby Pisuerga River.

The earliest recorded instance of the surname Simancas dates back to the 13th century, when it appeared in various historical documents from the region. One notable reference is found in the "Libro Becerro de las Behetrías de Castilla," a census-like document from 1352 that recorded the names of landowners and their properties.

In the 15th century, the town of Simancas gained historical significance as the site of the Archivo General de Simancas, a vast archive that houses invaluable records and documents from the Spanish monarchy, dating back to the Middle Ages. This archive has preserved numerous references to individuals bearing the Simancas surname.

One of the earliest known bearers of the name was Diego de Simancas (c. 1475-1541), a renowned Spanish theologian, jurist, and writer. He served as a professor at the University of Valladolid and later became a member of the Council of Castile.

Another notable figure was Juan Simancas (c. 1518-1576), a Spanish prelate and theologian who was appointed Bishop of Zamora in 1561. He played a significant role in the Counter-Reformation and attended the Council of Trent.

In the 17th century, Pedro Simancas (c. 1600-1670) was a Spanish painter known for his religious works, particularly those he created for churches and monasteries in the city of Valladolid.

The 18th century saw the rise of Alonso Núñez de Haro y Peralta, Marquis of Simancas (1698-1760), a Spanish nobleman and military officer who served as Viceroy of New Granada (present-day Colombia and Panama) from 1734 to 1741.
