Hortensia Jane - 'Or-ten-see-ah'
Lucretia Anneliese - "Lu-cre-sha'
Aloysius Jude - 'Al-lou-wish-uss'
Persephone? Hell yeah! Arabella? Go right ahead! Seraphina? God, that's gorgeous! Lucretia? NOOOOOOO!!!! An annoying double standard, I find. My names are not popular in the 'Vintage' trend hence very few people like them. But I guarantee, if Hortensia EVER makes an appearance in a popular movie then EVERYONE will be using it in no time. -_-
Tristen - 3/10 - It's not really a girl's name since it's not flattering enough. I also don't find it to be very good looking or intelligent on either gender. Have you thought about Trisha?
Meredith - 10/10 - I adore it. It's sophisticated, it's classy, it's tasteful and it's going to age tremendously well. A lot of people are bound to feed you the whole 'it's an old lady's name' line but, honestly, it's ANOTHER double standard. Arabella is very 'in' and popular, ridiculously so, because of the Harry Potter series. But, until recently, it was deemed one of the most granniest names in existence. So, if Meredith were to show up in a popular movie (like my example with Lucretia) then EVERYONE would be using it. Ah, the fickleness of mankind.
Blake - 0/10 - Flat out boy's name. It's just so nasty for a girl. Have you thought about Blanche?
Jace - 9/10 - A little plain but very powerful all the same. And I can definitely appreciate its age and minted appeal. But I'd still rather prefer something more majestic like Julius. Still, the decision is yours and yours alone.
Braedon - 8/10 - Brandon sounds better. But, overall, Braedon isn't that bad, for a trendy name.
Blue - 7/10 - As a first name, it's not very nice, rather like the name Grey. As a middle name, however, it's lovely. All in all, I'm just glad that you're using it on its correct gender; it was never meant to be a girl's name.
