[name_m]Frederick[/name_m] - a majestic name to match [name_m]Gustav[/name_m]
[name_m]Arthur[/name_m] - love the [name_m]King[/name_m] [name_m]Arthur[/name_m] association
[name_m]Walter[/name_m] - a strong and unused vintage name
[name_m]Hugo[/name_m] - I don’t like [name_m]Huey[/name_m] for a nn. [name_m]Just[/name_m] [name_m]Hugo[/name_m] is lovely.
Dislike…
[name_m]Osborne[/name_m] - doesn’t have the European flair of [name_m]Gustav[/name_m]
[name_m]Gunther[/name_m] - too matchy and reminds me of gunner
I voted for [name_m]Ozzie[/name_m] because I [name_f]LOVE[/name_f] [name_m]Ozzie[/name_m]/ Ossy/ whatever other spellings sound like this Unfortunately, I don’t care for [name_m]Osborne[/name_m], but I’d rather [name_m]Ozzie[/name_m] to [name_m]Huey[/name_m] (otherwise, [name_m]Hugo[/name_m] is my favourite full name from your list).
