Does [name_f]Guinevere[/name_f] [name_f]Rebecca[/name_f] work? I’d be adding a second middle name eventually.

Yes I think it has a nice rhythm.
I really love [name_f]Guinevere[/name_f] - great choice! However, I’m not a huge fan of it in combination with [name_f]Rebecca[/name_f].
I quite like [name_f]Rebecca[/name_f] as a name, but it has a very different feel to [name_f]Guinevere[/name_f] to me. It was hugely popular among my peer group at school, for example, so feels like a very girl-next-door, slightly dated name which doesn’t sit that well alongside obscure, mythical, romantic [name_f]Guinevere[/name_f]. Also, the R- beginning means that the two names blur together a bit when I say them.
Thank you @paw.
Thanks, [name_f]Katinka[/name_f]! I definitely see what you mean. I used to feel the same way about [name_f]Rebecca[/name_f], but [name_f]Rebecca[/name_f] by [name_f]Daphne[/name_f] [name_f]Du[/name_f] Maurier is one of my favourite novels, and it now feels more classic to me. I’ve decided not to use it with [name_f]Guinevere[/name_f] however.
