Baia

Taken from the name of a Basque river that has its source in Gorbeia and flows into the Ebro.
The source of its name is not quite so certain; there is, however, a theory that derives Baia from Basque ibai "river".

Galician variant of Olalla.

Variant transcription of Βαΐα, Βάϊα, or Βάια (see Vaia).
