I found Amzy as a surname for a Mohamed. I also found a Amzy who is from Saudi Arabia. But I've found many Amzy's who are American and by the rest of their names, I would guess European and Hebrew. My guess is that it's Hebrew and/or Biblical in some way. I could only find people with this name (even amount man and women surprisingly). Sorry I couldn't find more.
