I am taking these from the Brewer Dictionary of Phase and Fable.

Magi (The), according to one tradition, were Melchior, Gaspar, and Balthazar, three kings of the East.
The first offered gold, the emblem of royalty, to the infant Jesus; the second, frankincense, in token of
divinity; and the third, myrrh, in prophetic allusion to the persecution unto death which awaited the “Man
of Sorrows.”
MELCHIOR means “king of light.” GASPAR, or CASPAR, means “the white one.”
BALTHAZAR means “the lord of treasures.”

Now I know what "Caspar" was appropriate name for ghost in cartoon series by that name.
