Which is better?
Especially with the sibset-
[name_f]Hermione[/name_f], [name_m]Ignatius[/name_m], [name_f]Cordelia[/name_f] and [name_f]Persephone[/name_f]
[name_u]Oberon[/name_u] nn [name_m]Obie[/name_m] or [name_m]Bear[/name_m]
[name_m]Absalom[/name_m] nn [name_m]Abe[/name_m] or [name_u]Sal[/name_u]
Any thoughts would be appreciated!
Thanks 
[name_u]Oberon[/name_u]. [name_m]Absalom[/name_m] feels especially solemn and Biblical with [name_f]Hermione[/name_f], [name_f]Cordelia[/name_f], [name_f]Persephone[/name_f], and [name_m]Ignatius[/name_m].
[name_u]Love[/name_u] [name_u]Oberon[/name_u] nn [name_m]Obie[/name_m] or [name_m]Bear[/name_m], with and without the sibset.
My only association for [name_m]Absalom[/name_m] is biblical, so it seems different.
[name_m]Absalom[/name_m] seems difficult to pronounce to me. A bit of a tongue twister.
I love the name [name_u]Oberon[/name_u] and I think it works much better with that sibset. [name_m]Absalom[/name_m] just seems dark and biblical.
[name_u]Oberon[/name_u] in general and for your specifications! None of your other names are Biblical, so [name_m]Absalom[/name_m] sort of sticks out. To me, anyway. I love [name_m]Absalom[/name_m], but I’m not sure it works best with [name_f]Hermione[/name_f], [name_m]Ignatius[/name_m], [name_f]Persephone[/name_f], and [name_f]Cordelia[/name_f] (which is very literary/ancient/mythological). [name_u]Oberon[/name_u] is such a great Shakespearean name, just like [name_f]Cordelia[/name_f]! I like the idea of [name_f]Cordelia[/name_f] and [name_u]Oberon[/name_u] together, like [name_f]Hermione[/name_f] and [name_f]Persephone[/name_f]–two mythology names, two Shakespearean names. Now you just need another ancient [name_m]Roman[/name_m]/pope name.
[name_m]Absalom[/name_m] was a really evil guy with an awful end. I’d never name a child that.
I think you could use either, but [name_u]Oberon[/name_u] as king of the fairies seems to fit better with [name_f]Hermione[/name_f] and [name_f]Cordelia[/name_f]. And I suppose with [name_f]Persephone[/name_f], though that still strikes me as a victim’s name.
[name_m]Absalom[/name_m] on the other hand is not a whimsical name. I think of the Bible and [name_m]William[/name_m] [name_m]Faulkner[/name_m], both rather heavy in nature. It goes with [name_m]Ignatius[/name_m] but less so with the rest.
