The history of the last name Ostolaza

The surname Ostolaza originated from the Basque region of Spain and France, dating back to the late medieval period around the 13th century. It is believed to be derived from the Basque words "osto" meaning leaf or foliage, and "laza" meaning glade or meadow, suggesting the name may have referred to a person who lived near a leafy glade or clearing in a forested area.

One of the earliest recorded mentions of the surname can be found in the Codice de Ronces, a 14th-century Basque manuscript, where it appears as "Ostolaza." This spelling variation indicates the name's long-standing presence in the region.
