Little sister name for Elizabeth

Hi,

We’re having another baby girl in May and looking for some suggestions on names. We have been considering the following names:

-Rebecca (Becca/Becky)

-Rosalie (Rosie)

-Charlotte (Lottie)

-Emilia (Ellie)

I think my favourite is Rosalie though I was not sure if it’s a bit too different as I haven’t met anyone with the name. What do you think of the names above to go with her sister’s Elizabeth? Also very welcome to any suggestions that are of a similar type!
