What is Felix's brother or sister called?

[TheCharWoman]

Early days (so DH won't talk baby names with me!) but looking for a name for Felix's little brother or sister.

Would like a name with similar level of popularity as Felix (i.e. it is outside top 100, but everyone knows how to say/spell it), and would prefer a name that doesn't have an obvious automatic nickname (so not Victoria or Jonathan for example).

When DS was born, the only name we had for a girl was Lara if that helps!

Any ideas?

Kitty is Felix's sister, I think!

Astrid or Milo

Hugo & Martha

Lyra Lula xanthe violet Beatrix ivy all lovely

What is your surname? And what about Peter really cute and not popular?

Huge or Eloise

Sorry - autocorrect changed Hugh to Huge.
