Hmm, I like Brahm, but I've never heard of Rahm. It's not bad. I want an a- name to follow it for some reason. And preferably a longer one. How about
Rahm Alexander
Rahm Amadeus (I like thre repetition of Ms)
Rahm Emmanuel (not an a, but I like this one too)
Rahm Anthony
Rahm Antonio
Rahm Absalom
Rahm Augustus
Rahm Alastair
Rahm Alessandro
Rahm Alphaeus
Rahm Augustine
Now that I think about it more, over vowels might also be nice.
Rahm Oliver
Rahm Orlando
Rahm Everett
Rahm Elliott
Like any?
