Welsh has mutated over the years, so you would need to find possibly an old copy of the mabanogion or possibly talk to someone who knows the language intimatly. Unfortunatly even though I live in Wales and was born in Wales I just can't speak Welsh. OT: But I do love the Celtic tales of Branwen and the Myth of the Morrigan*. If its possible can you add these words that the morrigan was meant to have spoken in some sort of writen passage related to the celts. It is her prophacy of the end of the world *Celtic goddess of Death and destruction.
