Having looked at their details in 1911 census, this is very likely my great-grandparents, who lived in a farmhouse at the end of a nearby road (at the back of the Holbrook Royal Hospital School). I believe the house is now owned by Griff Rhys Jones. I have been to the graveyard 2 years ago on trip to UK but did not find the stone, only one for Susan Powell. Apparently the stone is near or in a hedge.
