What goes well with this sibset?

A friend of mine already has 4 girls and would like another baby when her youngest is a bit older and we were talking about names. I promised her I would come up with a good name to fit with her children but I’m struggling.
She has:

[name]Jasmine[/name] [name]Leigh[/name]
[name]Sophie[/name] [name]Marie[/name]
[name]Amie[/name] [name]May[/name]
[name]Rosie[/name] [name]Ann[/name]

Any suggestions for either girl or boy that fit with her style?

My first thought for a girl is [name]Ella[/name] [name]Grace[/name]. For a boy, [name]Jacob[/name] [name]Michael[/name] or [name]Samuel[/name] [name]Andrew[/name].
