On the baby-names page, there is a link for Irish names, one for Scottish names, but none for Welsh names! Why?
We could start with Seren (Star), Enfys (Rainbow), Gareth (a Knight of the Round Table), Derwyn (Oak tree),Emrys (version of Ambrose), Dilys (True),Medeni (September-born), Teifi (name of a river), etc etc.
