Thoughts on our girls short list please?

[pegster]

Our criteria has been a welsh first name & an english middle name but we live in England so want something with a fairly obvious pronunciation!
We have a 3 syllable surname starting with E. Happy to do a bit of swapping around between first & middle but want to avoid to -a endings together or odd initials etc.
Thoughts welcome

Alys Martha
Betsan Iris
Mali Thea
Menna Xanthe
Olwenna Poppy
Seren Daisy

I'd go for Seren Martha Rose (sorry just added another mn but think it flows well!)

I like Seren best as a first name and think it goes with Martha or iris better than Daisy. Or Seren Alice. Alys woudl be my second choice and think it goes well with Martha.

Alys Olwenna
Alys Daisy
Seren Poppy
Seren Iris

Alys Martha
Seren Daisy

Are both pretty.

How do you pronounce Olwenna? Is it OlwEnna or OlwInna?

Not keen on Betsan, sorry but to me it sounds like disinfectant.

Hmm, Alys & Seren are my favourites too but DH is currently keen on Olwenna (pronounced Ol-Wen-a with the stress on the middle Wen). I think a 3 syllable first name is a lot with a 3 syllable surname?
