Guglielmo

Anyone with that last name is cool. They are also fun, caring, and great at sports. They are very attractive, and if you know one you're blessed. They are most always popular, and nice. They are strong-willed and sarcastic, but do not forget that they will take the shirt off their back if you need it, even if they complain they're cold. You can always trust a Guglielmo!

That's a Guglielmo? I knew it! She/he is such a qt!
