I think Vanderlyle is a completely made up name by [name]Matt[/name] Berninger, the frontman of the band The National, but it just sounds awesome. There’s [name]Vander[/name], and there’s [name]Lyle[/name], so maybe it could be a variation for them.
Adua is an old-school iItalian name, used especially when we used to conquer other places. I also heard [name]Olanda[/name], but the entry is bare. I believe that it’s basically a misspell for [name]Iolanda[/name], but it is also the translation of [name]Holland[/name] in Italian. Another Italian oldie is indeed Isolina, which is not featured as sraexx suggested.
