You love Lapis Lazuli, too!? I thought I was the only one! It would just make such a cool double middle name for a boy, I totally agree. The sound of
Tarquin is generally nms (it reminds me of harlequin), but is ok I guess. I really can't say much, considering how I'm going to be the one here to name her first son
Constantine LOL... most of society (mainly those NOT from BtN) think I'm flat out nuts, but that's unrelated. Anyway, here are those opinions you asked for:
Cecilia -- I've never really liked it, but would still be happy to see it amongst all the Madisons of today.
Joan -- I may not be very religious (at all), but there is no denying that
Joan of Arc was one hell of a woman! If I were ever to name my daughter after somebody / something specifically
Christian, it would be
Joan.
Minerva -- We all know about my stubbornness of -er, -or, -ar, -er (damn it feels like I'm conjugating words in Spanish here) sounds, but
Minerva would just be so undeniably cool to see. If, many years in the future, you DO use this name, you have to tell us all and we'll have a wild party cause it's awesome.
Benedict --
Arnold! But I know you're sick of people saying that. Honestly, I love the sound, but the sandwich and backstabber always come to mind, despite it's nice qualities. Again, I'd still be thrilled (and I really mean it) to meet a young
Benedict.
Cornelius -- Believe it or not, I know a
Cornelius.
He goes by the nn Corny (and loves it, go figure). I really don't like the sound because of the -or deal, but again, just like all of your other choices, it would be such a thrill to see it used.
