Can you help me name my puppy?

My dog just had nine Labrador puppies and we are going to keep one. We have a Yellow Labrador who is 7 and his name is Maximus (he's 95 pounds). We are going to keep a Black Female and cannot decide on a name. I want something cool that goes along with Maximus. I was thinking maybe Roxy, but I want some other ideas. Thanks in advance. :)
