It's the natural progression from Isabelle and Eliza (all variants of the same)

Yes variants of the same name but different names in their own right.
thank you for the suggestions everyone. we're still non the wiser!

Since you've already got two variations of Elizabeth how about a third?

Beth
Elsa
Lizzie
Bella

Alice or Marianne

Jemina

Sophie

Matilda

Morgan.

Isabelle and Eliza are both evolved from the name Jezebel so I'd call #3 Jessie to keep in the same theme.

Rosie
Charlotte
Matilda
