For context, Ross Bagdasarian (Dave's creator and alter-ego) was a proud Armenian but (if I recall correctly)used the "Seville" name as people would be able to say it easier.

With this in mind, would this mean Dave's Armenian? If so, did anything from the "Chipmunks" ever even mentioned his heritage? Given that Dave's parents from the 80's show had American accents so maybe Dave was a third generation immigrant?
