Mago Bill: Yes; this is related to my Irish great grandfather, Mago William Sheehan, it is more about the Balearic Islands, Hannibal, and a book.

Another early Mago was Mago Barca of the late third century BCE. He was Hannibal's brother and a Carthaginian general. He was also the youngest son of Hamilcar Barca of the Barcids. 

The Balearic Islands seem to have an Irish connection of some sort. On Menorca Mago Barca lent his name to the city still called Port Mahon. Does not Mahon seem to have a bit of an Irish ring? The typical Mahon egg sauce that has conquered the word is known as mayonnaise! Isn't there a mayo something  something or other on "the old sod?"

I believe that there is a book about this Mago that you may enjoy reading it's by David Anthony Durham,   Pride of Carthage
