Basque surnames

Basque surnames are surnames with Basque-language origins or a long, identifiable tradition in the Basque Country. They can be divided into two main types, patronymic and non-patronymic.

The patronymics such as Aluariz (probably Alvariz, child of Alvar, as in the past 'u' and 'v' were indistinguishable in writing), Obecoz or Garcez are amongst the most ancient, going as far back as the 10th century.^[1] The Basque monarchy, including the first king of Pamplona, Íñigo Arista of Pamplona, or Eneko Aritza, were the first to use this type of surname. Patronymics are by far the most common surnames in the whole of the Basque Autonomous Community and Navarre.^[2]

The non-patronymic surnames are often toponymic ones that refer to the family's etxea, the historically all important family home. When a farm (baserri) was rented to another family, often the new tenants were known locally by the farm name rather than by their officially registered surname. They also referred to the occupation of the head of the family such as Olaberria ("the new forge") or Salaberria (new farm/farmer) or could describe where their home was such as Elizondo ("by the church").
