Boys names are hard.

Of that list, I prefer Logan. I forgot about the Wolverine reference, but given I've only seen the movie, I wouldn't object on that basis (Hugh Jackman buffed up and being a bad boy )

Alternatives for Judas are Jude or Judah.

Get your DH to come up with a list of names, not just Ronan and Brian. He's going to have give them up if you're dead against them. Then we can rank his list

Whilst we're on Scottish names ending in 'n', do you like:
Cameron, Warren, Kevin, Gordon, Graham, Paton, Lachlan, Caelen
