Can I use Raphaelle?

[RoseApp]

So girls names we have:
Xanthe
Catja
Robyn
Raphaelle - I am fixating on this now I love it but will it work in this country? We do have French connections so would want this rather than Rafaella

Do any of them work?

They are all beautiful and unusual. The only one which could be a difficulty is Catja if you intend the pronunciation to be Kat-I-ya? I’ve never seen it spelled that way and plenty of people i know already have issues with the traditional spelling.

I've never come across a Raphaelle but I love Raphael, and why not?
They are all lovely. I would think the Katja spelling would be more familiar here.

Possibly ignorant question, how is Raphaelle pronounced differently to Raphael?

Great names! Raphaelle works fine.
