I agree with Lulu, Antheia Archer is beautiful!

Some others -

Tiera - Yep, DD's name, I love it! (pronounce like Kira but with a T)
Ebony
Eleanor
Lilian
Madison
Felicity
Maya or Mya
Caitlin
Cassidy
Ivy
Rose
Violet
Tabitha

Good luck with it all!! DH can't decide on one name and it's only our second baby, I can't imagine how hard it would be to decide on 3 names for your fourth!!!! Your children have gorgeous names, you'll find the perfect one in no time.
