Naming our 4th child

[K8MMA]

I need some help!
Baby number 4 is going to be born in a matter of weeks and we're struggling when it come to a name.
Both myself and DH like the first names, Charlotte & Emma.
But we need a middle/second name. All 3 of our children have double barrelled first names, and we want the same for our last baby.
TIA

Not keen on the name Charlotte sorry.
But as a suggestion

Emma Charlotte
Emma Molly
Emma Kate
Emma Pearl
Emma Thalia
Emma Lynn
Emma Joy
