Yes, the families are headed by Kings and their heirs are designated Crown Princes. Even dispossessed royals are usually defined by the territory they used to rule. The wesen ones aren't. There are certainly plenty of places where the other 6 families could be based out of.

As you point out there is no shortage of places where animals were worshipped. We've not seen the other 6 families. We could speculate that Russia, China and Japan are potential sites based on the fact Eric was negotiating with the other families and  those countries have been mentioned. Fact is, we just don't know.
