Yes Skoosh,Mawr is big and Cefn is back.It should be said as;Kefvun Mowr.The un as in unknown and the mow as in owe for pain!

You do realise you are saying it is pronounced as "mowr" and they are going to say it as mo-er as in "mow the lawn?

- phonetically in the English language .
It's more like this for the English language- Can you imagine a cat saying yawrrrrr -change that Y to an M and really roll the R at the end of the word then you have mawr
cefn sounds a bit like kevin
I still haven't worked out how the hell you put ll, or ch onto paper to explain to non speakers, the sounds -It is impossible to put it into English phonetics.
kind regards:)
