I too say ma-ducks.
Personally I love this name. It's unusual without being over the top, masculine without being overly macho, and I could just as easily see it on someone's stationary as I could the cover of Rolling Stone. No matter what I see a
Maddox as a very strong personality, certainly not someone to be triffled with.
Maddox and
Casey make great brothers; couple of rouges. If you are worried about the Jolie-Pitt association
Madoc is a fantastic alternative. Otherwise I really do love
Maddox.
