sgbright, Just an update for you. The newspaper article was written in an old style of Welsh but I have been able to translate it for you and all I need to do is check it again and type it up and post it here. I'll do that later today or tomorrow.
Secondly, I was in the Archives again and can confirm that your relatives were buried in the St Mary's Cemetery in Caerhun. I then drove to Caerhun and took the photos of the graves. There are two graves next to each other and the first photo of the graves No A065 , the one with the chain link fencing has the following inscription although it is not clearly visible:-

Also Susannah Anne infant daughter of the above who died August 2nd 184- (number not shown)
The second grave No C075 has this inscription:-

Also John Hughes Elias second son of Edward Elias Gorswen born August 5th 1852 died April 20th 1896
