Welsh girls names

[overagain]

DH is half Welsh. We live in England and are unlikely to ever live i Wales, we may visit on holiday though (no family living there).

DHs DGM passed away last year, she had a very Welsh name, but hated it but was very proud of her Welsh heritage and other Welsh names so we would like to honour that.

I'm not keen on Ffion or Carys/ Cerys but do like Seren though realise it is very popular in Wales (never met one myself). Anwen and Tanwen are out though due to family names.

Any suggestions?

Shwmae! It would be Su'mai in North Wales.

How about Eos (Ay-oss). Welsh for nightingale.

Mabli is pronounced Mab-lee.

I was born and brought up in Wales so May have more of a fondness for some due to that but I like:

Catrin (and can always be shorted to Cat obviously)
Carys
Rhian (rh-ee-an but I've heard plenty of English people pronouncing it as ree-un which isn't nice imo)
Cadi
Haf (means summer)
Eira (means snow)
Awel

I love Seren (personal meaning to the name) but I am at over the welsh border in England now and I've heard a fair few with the name.

Rhian gets called Ree-Anne. Awful. Rhian in welsh is lovely.
Awel is Breeze. I wouldn't.

We have an Olwen, which never seems to cause pronunciation or spelling issues
