I like
Hadrian more every time it's mentioned! It's got a nice cuddly classics-professor feel to it (like
Atticus, only less trendy), it's familiar while being fairly uncommon, and it's fun to have your own namesake wall.
It's also a whole lot fresher than
Adrian, which is definitely going grey. If the local accent where you live drops its Hs, there might be confusion sometimes, but it's easily corrected. The only
Hadrian I know of never used an nn, but Hay and Hady seem like the most logical.
Can't warm to
Everett. It probably feels quite traditional in the US, but it isn't here, so it seems mismatched with
Patience.
