My brother, born 1977, is named Cade. My mother chose this name because of its Southern (Kentucky & Tennessee) and Irish roots. People compliment his name all the time! It's simple and strong.
I think Cade is a really unique name. It's one that you don't often hear, but I like it. I think Cade would make a great middle name, I'm not so sure about it being a first name though.
