As I said, we have this.
Middle names are Paul (after dh Grandad)
Russell (after my Dad - not a opoular or trendy choice, but my Dad is delighted).
With 2 syllable first and last names you can have either a one or 2 syllable middle name I think.
I don't think I would like the -n N combination, but I am supposing the N middle name is important to them.
Not something that also ends in N - like Nathan. Just doesn't trip well off the tongue.
Hope she can decide what to do - I found naming pretty stressful myself
