This suggests the name may have originated from a specific location or settlement characterized by muddy or swampy conditions.

One of the earliest recorded instances of the name Loustaunau can be found in the 14th-century cartulary of the Monastery of Roncesvalles in Navarre, Spain. This medieval manuscript mentions individuals with the surname Loustaunau residing in the nearby villages and towns.

In the 16th century, the name appears in various municipal records and census documents across the Basque region, often spelled with slight variations such as Loustaunau, Loustanau, or Loustanó. These variations likely reflect the regional dialects and orthographic practices of the time.

Another prominent individual was María Loustaunau, a Basque noblewoman from the 18th century, who was known for her philanthropic efforts and her support of educational initiatives in the region.

In the 19th century, the surname Loustaunau can be found in various genealogical records and parish registers, particularly in the Basque provinces of Spain and the neighboring regions of southwestern France. One notable figure from this period was José Loustaunau, a Basque scholar and linguist who made significant contributions to the study and preservation of the Basque language.
