Girls:
Belphoebe - it's definitely pretty, but I'm not sure if it would be better to just use
Phoebe. It doesn't really have good flow. I will say however that it would be a unique, nice long-form name for someone called "
Belle Phoebe."
Bellona - isn't she a war goddess? I do like the sound of it, but I wouldn't use it as a first name.
Briallen - maybe a bit of a GP.
Briallen is a very sweet name, though it hardly comes up for consideration on my lists.
Briony/Bryony - All I can think of is
Briony Tallis.
Boys:
Balfour - fusty, and reminds me of the graduation and yearbook company. However, I'll admit I'd think it was cool if I saw it on a person.
Barnaby - prefer
Barnabas.
Baltasar/Balthazar - don't like
Baltasar, but love
Balthazar. Really distinctive-sounding.
Bastian/Bastien - only as a nickname for
Sebastian
Benson - definitely not. If
Ben is up as a nickname, my thoughts would be for
Benjamin,
Benedict, or even
Benaiah.
Benson sounds like a dog's name more than a person's.
Bill - I've always loved
William but
Bill, meh. If a nickname were necessary for
William (which for this generation, I don't think it is) I'd use
Liam.
Blake - better as a middle name than a first name, imo. I like it some.
Björn/Bjorn -
Björn is preferable, but wouldn't use it partially because the English language isn't too favorable to diacritical marks in names, and the SSA won't distinguish between them.
Brennus - looks kind of made-up...like a masculine form for
Brenna, or someone didn't think
Brendan was proper enough for them.
Brynjar - would be awesome if I actually encountered one, but I wouldn't personally use it.
Unisex:
Beckett - I don't consider this unisex. Fine as a middle name for a boy, but don't think I'd ever use it.
Briar/Bryar - lol nope, and I feel it's more feminine than masculine. Either way if I were going for Disney I'd just use
Aurora.
Brook - okay, I can actually see this as unisex. Still wouldn't use it.
