I went to St Agnes Cemetery and took these three picture of John and Selina's grave. It's in the neglected part of the Cemetery but someone may have visited the grave in recent years as artificial flowers and some small plant pots were on the grave.
After visiting there I went to Glan Conwy and had a walk around the old part of the village but couldn't see Gorphwysfa so it's whereabouts are a mystery for now.
Just to give you an idea of the area where your ancestors lived I've taken photos of the terrace of cottages called Pen Tai, the Chapel is very near the cottages and looks down on Isfryn,
The photo of the lane was taken in front of the Chapel and Isfryn is on the left looking down. The mountains in the distance are called the Carneddau and the views from Pen Tai in the old days must have been spectacular.
