Close names

Kyristen
Okay, my sons father named him. I love his name. It's Brayden Michael, he's named after his daddy. 
I'm finding out soon what I'm having with our second. He's not in the picture, so I don't have his help on this. If it's a girl I want to go with Braylen Elizabeth. I LOVE IT. She would have my middle name. I know it's close but I absolutely adore it. But what if I have a boy I have no clue!!! I would want it to have a relative middle name but how do I choose which one? I'm stuck. Boys are for daddy to handle...
