Is Agassi a Persian?
I think he is Italian.
^^^ Whoever answered this before me, he's definitly not italian. He is Assyrian.
The answer to your question is no, the Agassi name is not royalty. I know how much whoever has the name Agassi wishes that their name as well as themselves were royalty, but I just hate to be the teller of bad news but keep dreaming. So not only is the name Agassi a pedant name, but it is also just a plain strange name.
