> Andrea (on-dre-ah vs and-ree-ah) is a true name collision.

What do you mean? The Italian male name Andrea and the English female name Andrea aren't unrelated names that happen to be spelled the same way. They are one and the same name, both derived from the Greek word for "man"; the Italian name has managed to remember that it's overtly masculine and the English name has forgotten this.

I mean that you can look at Daniele or Danielle and guess if it's an Italian guy or an American girl. You can't do the same for Andrea.
