Liland,

Before the Unification of Italy there was indeed a "Kingdom of Naples and the Two Sicilies" it coveredNaples, the island of Sicily and a chunk of the mainland, presumably this was the "second" Sicily. If I recall correctly, during the Napoleonic period, the Kingdom was given to one of Napoleon's Marshals Joachim Murat (who was, I think, also his Brother-in-Law).

Best Wishes.
