Welsh girl names - Help

[Cookalia]

We are really struggling with girl names.
It needs to be Welsh but work in Welsh speaking Wales and English speaking Wales and can't have a LL in it.

We have tended to like 'dated' names over current popular ones.

Megan, Bethan, Rhian, Carys etc are all nice but too run of mill.
Siân and Sioned also can't be used and nothing that begins with a T

I love Mali and Cadi.

Ffion is beautiful ❤️

Rhiannon?

Nia

Siwan.
Meinir.

Ceinwen

Phyllis Doris?

Oh, no good, LL, otherwise...

Rhiannon
Arwen
Eleri

I love Tesni

I love olwen.

Meinir is lovely.

Heulwen
Delwyn
Aneira
Ceridwen
Eleri
Enfys

Eilonwy

Ffion

Lowri

Lowri
Efa
Eira

Rhianwen

Bettrys
Enfys
Eswen
Glesni
Tegwen

I do like Alys too but, to me, it’s less of a Welsh name as such and more of a Welsh-style spelling. Some of the others have more to them somehow.

Lynwen, Elin, Heddwen

Maybe Haf as a middle name

Eluned is also nice

Einir is nice too.

Merryn, Bettrys and Marteg aren't welsh girl's names. Marteg is a river.
Enyd is spelt Enid.

Meredyth is spelt Meredith, and as I previously posted is the anglicised version of a boy's name.

Blodwyn is spelt Blodwen. Names that end in -wyn are boys' names. Blodwyn isn't a boy's name.

Iona is welsh. Usually given to girls born in January.

I liked the suggestions of Llinos and Gwenllian when the OP states
"It needs to be Welsh but work in Welsh speaking Wales and English speaking Wales and can't have a LL in it."

Enyd is spelt Enid

Please pop over and tell my eighty-year-old, Welsh-speaking Great Aunt Enyd, Mike. I'm sure she'll be glad to be corrected.
