DC5 (DD4) what goes with her siblings names?

[whostolemynamebook]

I name changed as am going to list all my dcs names!

siblings are
Jessica Alice
Jacob Alexander
Bethan Marie and
Emily Grace

MIL likes Anna and dh like charlotte but i just fancy something a bit more unusual, I am Welsh and like more "welshy" sounding names buy DH and his family are english and we live in England so they are not so keen.
I love Gwyneth which was my grandmothers name but again dh not so keen and i really dont want to force a name on him!.

any ideas? anything slightly more unusual that would not look too out of place with my older dcs names?

I always liked Carys (I'm 1/4 Welsh and my grandma was a Gwyneth too!)

oh should add my surnames begins with K :).

I like Carys but worry about surname clash - although alot of names seem to clash with my surname for some reason

What about Seren?

Anna is lovely, very elegant indeed.

Angharad
Artemis
Beatrix
Catharine - Kitty
Ffion
Gaia
Hermione
Isolde
Jemima
Paloma
Seraphina
Tabitha

How about going for some of the more mainstream welsh names - so they're unusual in England but still a bit familiar sounding:

Elin, Catrin, Lowri, Megan, Mali?

Welsh names that are common in England? I'm Welsh and my DH is English, we live in England and DS has a very Welsh name and so will his new sibling, however, we plan to move back to Wales before they start school.

How about Rhiannon, Sian, Angharad, Bronwen, Megan, Bethan, Elin, Tegan, Rhian, Sara, Gwen, Cari, Ceri?
Some of those are so popular Worldwide people probably don't even realise they are Welsh.

My cousin is Carys, surname starts with a C (but hard C sound, same as a K), and I think it sounds lovely! She's Carys Eve.

Gwen is lovely

Alexis, Ariel, Bronwen, Bryony, Camilla, Cerys, Dana, Esme, Effie, Felicity, Francesca, Farrah, Gabriella, Giselle, Hope, Johanna, Kendall, Lara, Morwenna, Marissa, Natasha, Phyllida, Rhiannon, Robyn, Seren, Skye, Sasha, Tegan, Thea, Xanthe, Zia.

I second or third the suggestion of Gwen - lovely lovely name.
