If I like Elowen, Lowenna and Eirwen

[Ididivfama]

What else?

DH is not being helpful!

I came on to say Morwenna. (Influenced by Doc Martin).

Kerensa (but pronounced with a sharper ‘z’ sound)

I know a Tonwen which I think is beautiful.

@TeamSleep , I think Mabon sounds fine but definitely masculine.
@Thingsthatgo , Tonwen is a new one on me. Are the parents surfers?

Morwenna is nice. It's cornish and is said to mean tern (sea swallow). Morwen is welsh and I think it means maiden.

Gwylan and Gwennol could be used as names.
