@PeachyMum maybe I should suggest Sooty for a sibling name
DH really only likes [name_m]Basil[/name_m], I did suggest Bastian/Sebastian nn [name_m]Bastian[/name_m], but that was quickly shut down.
@katinka I’d never thought about [name_m]Russell[/name_m] and [name_m]Basil[/name_m] being too close, I think I’d probably still go for it. Our girl choice is [name_f]Alice[/name_f], so clearly we just like S and L sounds! [name_m]Basil[/name_m] [name_m]Nye[/name_m] is currently my favourite for a middle name, but [name_m]Colin[/name_m] is a family name which does sway me. I like [name_m]Corin[/name_m] but we have a friend with the name who is great but who we don’t necessarily want people to think we named after (we had to rule out [name_m]Arthur[/name_m] for the same reason)
@marysia my husband is opposed to nicknames, but I’m definitely not! I don’t love the nickname [name_m]Baz[/name_m] though, hopefully I’ll come up with something I prefer. (It’s fine if he becomes [name_m]Baz[/name_m], but it’s not my first choice).
@Greyblue DH loves it because of the link to nature - we grow the herb in out kitchen/my husband cultivates it as a gardening hobby, then he played a computer game with a character called [name_m]Basil[/name_m] and it sealed the deal for him. I really like [name_m]Otis[/name_m], [name_m]Alfred[/name_m] and [name_m]Ralph[/name_m], so thinking about [name_m]Basil[/name_m] in that sort of cohort does help!
I definitely might call him Herb/Herbie, I think that’s cute 
@cms1512 I definitely don’t dislike the Great [name_m]Mouse[/name_m] Detective! 
DH has yet to come back to me with his middle name suggestions, although I have sent him my list. He seemed to quite like [name_m]Basil[/name_m] [name_m]Nye[/name_m], which surprised me. I explained that I like [name_m]Basil[/name_m] but I’m not excited by it, so a middle name that I love might be what seals it for me - he seemed on board with that as a method.
@Chococat I am quite concerned about the Fawlty [name_m]Towers[/name_m] association, but I think most of my friends will go to [name_m]Basil[/name_m] Brush instead (I hope). I don’t particularly like Fawlty [name_m]Towers[/name_m] and I am sure some older relatives will make the joke, but I am hoping that the association will fade.
@EdgeOfTheMeadow very helpful thank you! I do like names where they’re unusual but have a clear spelling (my real name is similar in that it’s used quite rarely in the UK - or was when I was born - but everyone knows how to say and spell it). I also love the idea of it being fun to do calligraphy with!
