Avalos surname meaning

Avalos (Spanish Ávalos) is a habitational surname, a variant of Ábalos from the town of Ábalos in La Rioja near Haro. The related form Dávalos preserves the preposition de, “from Ábalos.” Medieval spellings such as Dáualos appear in Riojan records, and the unaccented American spelling Avalos is standard in Census data. Families who left the town carried the place-name as a hereditary surname across Spain and later into the Americas. Place is high confidence for the Ábalos habitational origin shared by Avalos, Ábalos, and Dávalos; DAFN treats Avalos as that place-name variant rather than a separate etymology.
