You have such charming, literary names and I also like that they’re all well-established and not too stylised.
I would go, Amy-Louise, Thomas, Toby &
-
Elsbeth Ann nn Elsie
-
Emily-Rose (two honours as her name) and you can nickname Lily-Rose
-
Abigail Vera (I don’t think Abigail needs to be
hyphenated but Abigail-Rose Emily is pretty; good if you want two As and two Ts) -
Verity-Rose (with Verity a nod to Vera and Emily; I think Verity suits as a first more than Vera, just to explain thinking)
-
Rosemary Ann nn Romy (also keeps the letter O thread throughout the four names)
-
Emmeline Rose as an honour of Emily
-
Mabel-Rose Emily
Adelaide is beautiful but feels heavier than your others. I don’t think Norah or Stella suit your bucolic storybook set. Stella is too outward and showy and Norah, a bit too artsy & hip. I would keep this more genteel feel you have going.
