I always want to love [name_f]Agnes[/name_f] … but I just can’t. I’m not sure why! Same with [name_f]Agatha[/name_f], so maybe it’s the “[name_f]Ag[/name_f]” sound?
[name_f]Elizabeth[/name_f] is nice.
And you can totally use [name_u]Winter[/name_u] as mn for a [name_u]July[/name_u] baby - remembering that it is [name_u]Winter[/name_u] in [name_u]July[/name_u] for half the world!
