The history of the last name Aguilar

The surname Aguillar originated in Spain during the medieval period. It is derived from the Spanish word "aguila," meaning "eagle," which suggests that the name may have been used to denote someone who possessed eagle-like qualities or lived near an area associated with eagles.

One of the earliest recorded instances of the name Aguillar can be traced back to the 12th century, when it appeared in historical records from the region of Castile, Spain. During this time, the name was often spelled as "Aguillera" or "Aguilera."

In the 13th century, the name Aguillar was found in documents from the city of Seville, where it was associated with a prominent family that owned land and property in the area. This family's roots can be traced back to the Moorish occupation of Spain, suggesting a possible Arabic influence on the name's origins.

The surname Aguillar has also been linked to various place names throughout Spain, such as Aguilar de Campoo, a town in the northern region of Palencia, and Aguilar de la Frontera, a municipality in the province of Córdoba. These place names likely influenced the spelling and pronunciation of the surname over time.
