Italian or not?

[Olaf Solstrand]

There's one thing I've always been curious of...

Magica de Spell. Is she Italian, or does she come from another country, but 
live in Italy because here number one scheme includes an active volcano? If so, 
do we know anything about which country she's from? I always thought of her as 
either Italian or American, but she could come from anywhere if we say that the 
volcano is her reason to live in Italy and the dime is her reason to visit USA 
so often.

Have it ever been stated in a story what nationality Magica has? I know that an 
Italian story says that she supports the Italian national soccer team, but I 
don't concider that as a bullet-proof sign she's Italian. Unless, of course, 
that was stated in the story and it disappeared in the translation.

Hm... when I think of it, I remember another (Italian) story. One where Magica 
is telling Scrooge about her great-great-great-great-great-grandmother, who 
lived in a land up North with many other witches and moved South because she 
didn't want to be a witch. She came to a volcano and settled there, and we can 
only assume that is the same volcano as Magica lives by today. So... That story 
would mean that Magica and her family has been living in that sorcery shop for 
generations. But...

...why doesn't Magica have an accent, then?

Are there any sources stating Magica's nation of origin, except for the one 
I've already mentioned?
