My current shortlist is:
Jason
Luke
Toby
Robin
Aaron
I quite like Jason because it's a well known name but it's not as popular now so there won't be three Jasons in the same class at school.
Luke has a nice ring to it but I'm worried that DH will spend all his time doing Darth Vader impressions.
I love Toby but I don't want to use Tobias as my surname begins with S and I don't like the double S sound. Yes I know James ends in S but DH insisted!
People have commented before that Robin sounds a bit wet but it makes me think of Robin Hood and Robin Williams.
My MIL commented that Aaron was common which I was quite surprised at. I live in Northern Ireland so it would be pronounce Arran rather than Air-on.
