What a lovely list of names - I really like some of yours and your DH's list.
However you're brave asking for advice here! Lots of the Mnetters who post on the baby names threads are very conservative (small c!) about names and shoot down any slightly unusual names. So you'll find the general consensus is likely to be the most boring / well known names form your list (i.e. Sam and Rory - no surprise there!).
Also there is a - probably unconscious - bias to Anglicised names here. Often when OPs suggest Celtic names, you'll find people saying "you can't call your child that, they'll forever have to spell it, why don't you just call them a nice normal name like Edward or Harry (or whatever)". But they don't realise that if everyone took this advice then Welsh / Irish / Scottish names would die out completely over time, which would be a great shame indeed, and is the death of culture in action.
However it seems to me that you both like the more unusual names, so please, don a hard hat and don't listen to the boring people who would have you call your child something English plain, instead of something along the lines of the beautiful names you have listed above.
FWIW my favourites from your lists are Rudy and Inigo. Inigo was a favourite of my DP's and I suspect it'll be on any future list, should the occasion arise
I know a Rudy, it's a great name.
How do you pronounce Inaki?
I'll have a think about some other suggestions and post them here..
HTH
p.s. Sorry for the rant, this is a personal bug bear of mine!
