Middle name for Liam

[tinkerbelle]

Hubby and I can only agree on the name Liam for a boy... the thing is though he is pushing to pass down a family name "Brian" as the middle name.
What do you all think about those two names together?
Liam Brian ___ (our surname is double syllable). Does it sound funny having a short first name ending in 'm' and then a short middle name ending in 'n' - thats my thoughts..
I love Alexander as a middle name, Christopher or Benjamin because to me it seems to sound better having a longer middle name when Liam is a short name and our surname is also quite simple/short, but these have been ruled out by my hubby...
Any thoughts?
