The history of the last name Alday

The surname Alday is of Spanish origin and can be traced back to the medieval era. It is believed to have originated from the Basque region of northern Spain, where it was likely derived from the Basque word "alda," meaning "hillside" or "slope." This suggests that the name may have initially referred to someone who lived near or on a hillside.

One of the earliest recorded instances of the Alday surname can be found in the "Becerro de las Behetrías," a census-like document compiled in the 14th century during the reign of King Pedro I of Castile. This document listed individuals and their properties, indicating that Alday was already an established surname by that time.

In the 15th century, records show an individual named Juan de Alday, who was a prominent merchant and landowner in the town of Bilbao. His descendants continued to play influential roles in the region's economic and political affairs for several generations.

During the 16th century, the Alday surname appeared in various historical documents related to the Spanish conquest of the Americas. One notable figure was Pedro de Alday, a Spanish soldier and explorer who participated in the expeditions of Hernán Cortés in Mexico. He was born in the late 15th century and died around 1550.

Another individual of note was Miguel de Alday, a Catholic priest and theologian who lived in the late 16th and early 17th centuries. He was born in Navarra, Spain, and served as a professor of theology at the University of Salamanca, one of the most prestigious academic institutions of the time.

In the 18th century, the Alday surname was associated with the town of Álava, located in the Basque Country. Records from this period mention a family named Alday who owned significant landholdings in the area and played a prominent role in local affairs.

Throughout history, the Alday surname has been spelled in various ways, including Aldai, Aldaya, and Aldaye, reflecting regional linguistic variations and the evolution of spelling conventions over time. However, the core meaning and origin of the name have remained consistent, tracing back to its Basque roots and association with hillsides or slopes.
