My first thought is [name_f]Helena[/name_f] [name_f]Chrysanthemum[/name_f]. I guess I still haven’t completely gotten over [name_f]Chrysanthemum[/name_f] for you.
Cosima [name_f]Yvaine[/name_f]
[name_f]Tatiana[/name_f] [name_f]Marigold[/name_f] (since the first name starts with Ta, can we count this to honour TAM?)
[name_f]Proserpina[/name_f] [name_f]Helen[/name_f]
You have a beautiful name style. Not a single name on your UC is less than gorgeous. [name_f]My[/name_f] faves from your UC are Rosemerta [name_f]Marigold[/name_f] and [name_f]Petra[/name_f] [name_f]Apolline[/name_f].
From user suggestions I like [name_f]Cosima[/name_f] [name_u]Hero[/name_u] and [name_f]Rosamund[/name_f] [name_u]Hero[/name_u].
Tempest [name_f]Asterope[/name_f] Menodora; [name_f]Thallo[/name_f] [name_f]Asterope[/name_f] [name_f]Madelief[/name_f]; or [name_f]Thessaly[/name_f] [name_f]Aster[/name_f] [name_f]Minerva[/name_f]!
Okay, if I were naming a sister to your boys, my personal top pick would be [name_f]Valeria[/name_f]. I love [name_f]Valeria[/name_f] and I think it is a perfect match in style and sound for your sons.
To come up with a middle for it, though, I’m drawing inspiration from names I already know you like. I think [name_f]Valeria[/name_f] [name_u]Tempest[/name_u] or [name_f]Valeria[/name_f] [name_f]Thisbe[/name_f] would both be lovely, as would [name_f]Valeria[/name_f] [name_f]Helen[/name_f].
Twila Olympias [name_f]Petra[/name_f]!
All are names I remember you gushing about in the past and they’ve always stuck with me because of that.
Cassiopeia is still my favorite for you!
Maybe [name_f]Cassiopeia[/name_f] [name_f]Marigold[/name_f] [name_u]Hero[/name_u] or [name_f]Cassiopeia[/name_f] [name_f]Minerva[/name_f] [name_u]Jule[/name_u]!
Minerva [name_f]Antigone[/name_f] [name_f]Rosamund[/name_f], [name_f]Cressida[/name_f] [name_f]Helen[/name_f] [name_f]Yvaine[/name_f], [name_f]Clio[/name_f] [name_f]Persephone[/name_f] [name_u]Jule[/name_u], [name_f]Genevieve[/name_f] [name_f]Appoline[/name_f] [name_f]Cosima[/name_f], [name_f]Thisbe[/name_f] Olympias [name_u]Jule[/name_u], [name_f]Circe[/name_f] [name_f]Ambrosia[/name_f] [name_f]Alienor[/name_f], [name_f]Thessaly[/name_f] [name_f]Proserpina[/name_f] [name_f]Pearl[/name_f], [name_f]Artemisia[/name_f] [name_f]Fiora[/name_f] [name_f]Thallo[/name_f], and [name_u]Tempest[/name_u] Menodora [name_f]Circe[/name_f] also come to mind!
Sorry I listed so many! There’s just so many stunning names I imagine when I think of you. 
I love it. [name_f]My[/name_f] partner doesn’t as much.
@findemaxa13, I do like [name_f]Valeria[/name_f] a lot.
@regionlatbest, I haven’t thought about [name_f]Cassiopeia[/name_f] [name_f]Minerva[/name_f] [name_u]Jule[/name_u] in so long! Ooh, [name_u]Tempest[/name_u] Menodora [name_f]Circe[/name_f] is witchier than I am but man, that is a bad@$$ combo!
Oof, @SparkleNinja18, you win the right to name her for me. [name_f]Twila[/name_f] Olympias [name_f]Petra[/name_f] is impeccable and a combo I hadn’t put together.
Tisiphone [name_f]Alcione[/name_f] [name_f]Marigold[/name_f]! OR [name_f]Thessaly[/name_f] [name_f]Alcione[/name_f] [name_f]Marigold[/name_f].
but I really really love [name_f]Tisiphone[/name_f] for you 
I’m honored 
Roxana [name_f]Calliope[/name_f] [name_f]Helen[/name_f]
[name_f]Cosima[/name_f] [name_f]Tamsin[/name_f] [name_f]Pearl[/name_f]
[name_u]Artemis[/name_u] [name_f]Helen[/name_f] [name_u]Jule[/name_u]
