Cornish pronunciation

I'm interested in Cornish pronunciation, as well as that of the connected Celtic nations. Simple things like Celtic Keltic or Seltic to more complicated ones like Lanhydrock or Godolphin. So I was interested in the item in today's WMN living Cornwall which mentioned I don't necessarily consider myself as pure Cornish, though my Rawe surname goes back at least to the 12th century (Radulphus, introduced by the Norman Vikings, shortened to Raw by the Cornish and to Ralph by the English).

I thought this was very interesting as it strongly suggests the d is near silent somthing more like Raulphus. This presumably suggests the same for Godolphin.

 

The local coverage of St Piran day is also intersting - there's a strong view that Piran was Irish and known to the Irish as Ciran (probably pronounced more like we pronounce Kieran), the Irish also call their headlands cenn while the Cornish go with Penn..
