Historically, the Basque region has been known for its tradition of toponymic surnames, which reflect local geography and land properties. The appearance of the surname could date back to the Middle Ages, when families began to adopt names that identified their place of residence or property. The expansion of the surname to other regions of Spain, and later to America, may be related to migratory movements during colonization and European emigration in the 16th and 17th centuries. The colonization of America by Spaniards and other Europeans facilitated the dispersion of Basque-Navarrean surnames, possibly including Ostolozaga. The presence in the United States, although smaller, can be explained by more recent migrations, in search of economic opportunities.or for political reasons. The current geographical dispersion reflects, therefore, a historical process of expansion from a Basque nucleus to other territories, in line with the migratory patterns of the peninsula and the American colonies.

In addition, the distribution in English-speaking countries such as the United States may be due to the Basque and Spanish diaspora, which in some cases occurred in the context of emigration to America and later to North America. The small presence in Wales, United Kingdom, could be the result of more recent migratory movements or of families who, for economic or work reasons, moved to that region. In short, the history of the surname Ostolozaga seems to be marked by its origin in the Basque Country, its consolidation in that region, and its subsequent expansion through internal and external migrations, in line with the historical processes of colonization, emigration and globalization.
