Need inspiration for number 5

[FiveIsMoreFun]

My manager is looking for inspiration for number five and I know you lot will come up with whole lists of suggestions.
They havent found out the sex so are looking for boys and girls names to go with siblings Rosalie, Mathilda, Esther, and Stein.
(And yes, I've named changed just in case he searched me. )

Magnus
Caspar
Wulfric
Henrik
Rudy
Ludo
Ivan

Cora
Marianne
Tabitha
Anna
Laura
Lois
Vivian
Susannah

Quentin
Reuben

Clara
Florence

P.s are you sure about Stein? It means rock in German!

Okay, you got me on that one.
It's actually Stijn and I've no idea how to spell it in English without the ij.

We're not in the UK, which was another reason to post on here; he'll get a different selection of names.
