I usually like to keep their original names. I like the odd names they have like Uolle and Frila. I do change them sometimes if the name dosen't seem to fit. I have two kids right now that I changed the boy from Pop to Popi, and Cocoa to just CoCo. Also I remember changing Etna to Etta and Bolico to Boi. So I keep them as close to the original but with a twist.
