Living in the UK, but the name needs to be pronounceable by the rest of the family, who all live in central Europe.
I like:
Emil
Karol (I love this name, but I won't be using it because in the UK he'd probably just get a lot of raised eyebrows at best)
August (probably a bit too trendy now)
Konrad
Ansel
Are there any similar names I might not have thought of?
