We're having twin girls, and we're really undecided on a name for our our second twin. Vivienne Gray (nn Vivi, and Gray is a family name) is a likely candidate for twin 1's name, and we're thinking about Philippa (nn Pippa/Pip) or Felicity (nn Flick) for the second name.
Which do you like better, and why? Middle name would probably be Eve, Winter, or Eleanor. All of them are meaningful to us, so not just aesthetic choices.
