Help with suggestions for a baby brother for Michael...

[Playboxpony]

Got our girl's name sorted but struggling for boys. Names I currently like:

Murray (too many Ms with Michael?? But DP seems to really like it and not come up with anything else!)
Magnus (again, is it ok to have same initial as DS1?)
Isaac (is it too biblical with Michael?)
William
Fredrick
Robin

Friends have already used other names I also like, so the following are ruled out unfortunately : Oliver, Archie, Alexander, Samuel, Gabriel - but this gives you an idea of the kind of thing...
Help!

Nicholas, Joseph, Daniel, Simon, David, Robert?

My DS is Rohan Michael. I think those two names go together beautifully. I could imagine them as brothers names.

Seamus
Timothy

The Michael's I know have brothers Anthony and David.

The only one I really like from your list is Isaac.

How about:
Jonathan
Nathaniel
Leon / Leo / Liam
Elliot
Patrick
Christian / Christopher
Andrew
Daniel
Blake
Peter
Joshua

Luke

Patrick

I love Magnus!
