Dorian is handsome, youthful, menacing. The perfect vampire name.
Phineas is intelligent and a bit silly. Like an absent-minded genius professor.
Julian is pale, aristocratic, smug.
Ariel is light, fairy, masculine rather than feminine, but also with an androgynous quality. Like, I imagine an androgynous man rather than an androgynous woman.
Perdita is dramatic, sad, a bit silly. I think of the Discworld heroine, an aspiring opera singer, who renamed herself
Perdita X (her actual name being the far less glamorous
Agnes Nitt).
Odette is elegant, dainty, swan-like, with a brassy Germanic undertone.
