[b][name_u]Bellamy[/name_u] ([name_u]Bell[/name_u])
OR
[name_f]Briony[/name_f] (give me a 4 letter nickname if you can!) ;)[/b]
Of the two, I prefer [name_f]Briony[/name_f] (although I prefer it spelled [name_f]Bryony[/name_f]. It just looks more balanced to me?). The only 4-letter nns I can think of are [name_u]Bryn[/name_u] and [name_f]Bree[/name_f]. I prefer the [name_f]Brynn[/name_f] spelling ([name_u]Bryn[/name_u] is all boy to me!), but I could still envision [name_f]Briony[/name_f] nn [name_u]Bryn[/name_u]/[name_u]Brin[/name_u]. [name_u]Bellamy[/name_u] is nice, though, and what a lovely meaning!
[name_f]Briony[/name_f] (spelled [name_f]Bryony[/name_f]) is my favorite. I like the nickname [name_f]Briar[/name_f], which is five letters but it’s the only one I like!
I think [name_u]Brio[/name_u] would be a super cute nickname for [name_f]Briony[/name_f]. I prefer [name_u]Bellamy[/name_u] out of the two, [name_u]Bell[/name_u] is a cute nickname 
I hate [name_u]Bellamy[/name_u], but I love love love [name_f]Briony[/name_f], though I definitely prefer it spelt [name_f]Bryony[/name_f]. Four letter nicknames could be [name_f]Bree[/name_f], [name_u]Bryn[/name_u] or [name_u]Ryan[/name_u] though my favourite nicknames are [name_f]Briar[/name_f] and Bry.
[name_f]Hope[/name_f] that helps a bit!
I definitely prefer [name_u]Bellamy[/name_u]!
