There are various placenames in the Chiloé Archipelago with Chono etymologies despite the main indigenous language of the archipelago at the arrival of the Spanish being veliche. A theory postulated by chronicler José Pérez García explains this holding that the Cuncos (also known as Veliches) settled in Chiloé Island in Pre-Hispanic times as consequence of a push from more northern Huilliches who in turn were being displaced by Mapuches. While being outside traditional Huilliche territory the western Patagonian volcanoes Michimahuida, Hornopirén and Chaitén have Huilliche etymologies.
