I definitely prefer Agnes and Arthur
Idris.. this could just as easily be a girl as far as I'm concerned
Rowan.. I'm not sure how I'd pronounce it. Also, we have very different ways of saying "R" across Norway, so if you wish for a name that is pronounced somewhat similar across the country/countries I'd avoid starting with the letter R
Delia.. I don't know, I've never met anyone called Delia. It's easy enough to say though, and I'm sure I could get used to it
I prefer names that people immediately know how to spell, so your child won't have to spell it out loud all the time. My mom has a name she must spell out, which has always annoyed her..
Throwing in some examples of names that work well in both languages, and people spell right
Arthur, Gabriel, David, Benjamin, Jonathan, Vincent, Elliot, Julian, Oliver,
Agnes, Julia, Ellen, Linda, Olivia, Karen, Michelle, Lillian, Emma
Whichever name you do choose will be perfect for your child ❤
