Audrey Helena is lovely! :)
Okay...well, I love
Graham and pronounce it "GRAY-um". To me, it's warm and cuddly, friendly and bright, sophisticated and distinctive all at once; I think it ages well. However, it ends in "m" and if meant to be a first name for
Mitchell (handsome, by the way), I'm not wild about the flow.
Bruce is alright; never have been particularly drawn to it, though I do like
Bruce Willis. The actor and the mechanical shark from "Jaws" are my only real associations with the name. The name, itself, has a much more informal feel to it than either
Graham or
Audrey, in my opinion. I imagine a
Bruce to be active, athletic, bright.
Bruce Mitchell flows better than does
Graham Mitchell, but I prefer
Graham as a sibling to
Audrey.
